Configuring Server Boot

Contents

Configuring Server Boot

This chapter includes the following sections:

Boot Policy

The boot policy determines the following:

  • Configuration of the boot device
  • Location from which the server boots
  • Order in which boot devices are invoked

For example, you can choose to have associated servers boot from a local device, such as a local disk or CD-ROM (VMedia), or you can select a SAN boot or a LAN (PXE) boot.

You must include this policy in a service profile, and that service profile must be associated with a server for it to take effect. If you do not include a boot policy in a service profile, the server uses the default settings in the BIOS to determine the boot order.

Important:

Changes to a boot policy may be propagated to all servers created with an updating service profile template that includes that boot policy. Reassociation of the service profile with the server to rewrite the boot order information in the BIOS is auto-triggered.

Creating a Boot Policy

You can also create a local boot policy that is restricted to a service profile or service profile template. However, except for iSCSI boot, we recommend that you create a global boot policy that can be included in multiple service profiles or service profile templates.

Procedure
    Step 1   In the Navigation pane, click the Servers tab.
    Step 2   On the Servers tab, expand Servers > Policies.
    Step 3   Expand the node for the organization where you want to create the policy.

    If the system does not include multitenancy, expand the root node.

    Step 4   Right-click Boot Policies and select Create Boot Policy.

    The Create Boot Policy wizard displays.

    Step 5   Enter a unique name and description for the policy.

    This name can be between 1 and 16 alphanumeric characters. You cannot use spaces or any special characters other than - (hyphen), _ (underscore), : (colon), and . (period), and you cannot change this name after the object has been saved.

    Step 6   (Optional)To reboot all servers that use this boot policy after you make changes to the boot order, check the Reboot on Boot Order Change check box.

    In the Cisco UCS Manager GUI, if the Reboot on Boot Order Change check box is checked for a boot policy, and if CD-ROM or Floppy is the last device in the boot order, deleting or adding the device does not directly affect the boot order and the server does not reboot.

    Step 7   (Optional)If desired, check the Enforce vNIC/vHBA/iSCSI Name check box.
    • If checked, Cisco UCS Manager displays a configuration error and reports whether one or more of the vNICs, vHBAs, or iSCSI vNICs listed in the Boot Order table match the server configuration in the service profile.
    • If not checked, Cisco UCS Manager uses the vNICs, vHBAs, or iSCSI vNICs (as appropriate for the boot option) from the server configuration in the service profile. It does not report whether the vNICs, vHBAs, or iSCSI vNICs specified in the boot policy match the server configuration in the service profile.
    Step 8   Configure one or more of the following boot options for the boot policy and set their boot order:

    What to Do Next

    Include the boot policy in a service profile and/or template.

    After a server is associated with a service profile that includes this boot policy, you can verify the actual boot order in the Boot Order Details area on the General tab for the server.

    SAN Boot

    You can configure a boot policy to boot one or more servers from an operating system image on the SAN. The boot policy can include a primary and a secondary SAN boot. If the primary boot fails, the server attempts to boot from the secondary.

    We recommend that you use a SAN boot, because it offers the most service profile mobility within the system. If you boot from the SAN when you move a service profile from one server to another, the new server boots from the exact same operating system image. Therefore, the new server appears to be the exact same server to the network.

    To use a SAN boot, ensure that the following is configured:

    • The Cisco UCS domain must be able to communicate with the SAN storage device that hosts the operating system image.
    • A boot target LUN on the device where the operating system image is located.

    Configuring a SAN Boot for a Boot Policy

    You can also create a local boot policy that is restricted to a service profile or service profile template. However, except for iSCSI boot, we recommend that you create a global boot policy that can be included in multiple service profiles or service profile templates.


    Tip


    We recommend that the boot order in a boot policy include either a local disk or a SAN LUN, but not both, to avoid the possibility of the server booting from the wrong storage type. If you configure a local disk and a SAN LUN for the boot order storage type and the operating system or logical volume manager (LVM) is configured incorrectly, the server might boot from the local disk rather than the SAN LUN.

    For example, on a server with Red Hat Linux installed, where the LVM is configured with default LV names and the boot order is configured with a SAN LUN and a local disk, Linux reports that there are two LVs with the same name and boots from the LV with the lowest SCSI ID, which could be the local disk.


    This procedure continues directly from Creating a Boot Policy.

    Before You Begin

    Note


    If you are creating a boot policy that boots the server from a SAN LUN and you require reliable SAN boot operations, we recommend that you first remove all local disks from servers associated with a service profile that includes the boot policy.


    Procedure
      Step 1   Click the down arrows to expand the vHBAs area.
      Step 2   Click the Add SAN Boot link.
      Step 3   In the Add SAN Boot dialog box, complete the following fields, and click OK:
      Name Description

      vHBA field

      Enter the name of the vHBA you want to use for the SAN boot.

      Type field

      This can be one of the following:

      • Primary—The first address defined for the associated boot device class. A boot policy can only have one primary LAN, SAN, or iSCSI boot location.
      • Secondary—The second address defined for the associated boot device class. Each boot policy can have only one secondary LAN or SAN boot location.

      The use of the terms primary or secondary boot devices does not imply a boot order. The effective order of boot devices within the same device class is determined by PCIe bus scan order.

      Step 4   If this vHBA points to a bootable SAN image, click the Add SAN Boot Target link and, in the Add SAN Boot Target dialog box, complete the following fields, then click OK:
      Name Description
      Boot Target LUN field

      The LUN that corresponds to the location of the boot image.

      Boot Target WWPN field

      The WWPN that corresponds to the location of the boot image.

      Type field

      This can be one of the following:

      • Primary—The first address defined for the associated boot device class. A boot policy can only have one primary LAN, SAN, or iSCSI boot location.
      • Secondary—The second address defined for the associated boot device class. Each boot policy can have only one secondary LAN or SAN boot location.

      The use of the terms primary or secondary boot devices does not imply a boot order. The effective order of boot devices within the same device class is determined by PCIe bus scan order.

      Step 5   Do one of the following:
      • Add another boot device to the Boot Order table.
      • Click OK to finish.

      What to Do Next

      Include the boot policy in a service profile and/or template.

      After a server is associated with a service profile that includes this boot policy, you can verify the actual boot order in the Boot Order Details area on the General tab for the server.

      iSCSI Boot

      iSCSI boot enables a server to boot its operating system from an iSCSI target machine located remotely over a network.

      iSCSI boot is supported on the following Cisco UCS hardware:

      • Cisco UCS server blades that have the Cisco UCS M51KR-B Broadcom BCM57711 network adapter and use the default MAC address provided by Broadcom.
      • Cisco UCS M81KR Virtual Interface Card
      • Cisco UCS M82-8P Virtual Interface Card

      There are prerequisites that must be met before you configure iSCSI boot. For a list of these prerequisites, see iSCSI Boot Guidelines and Prerequisites.

      For a high-level procedure for implementing iSCSI boot, see Configuring iSCSI Boot.

      iSCSI Boot Process

      The Cisco UCS Manager iSCSI vNIC and iSCSI boot information created for the service profile is used in the association process to program the mezzanine adapter, located on the blade server. After the adapter is programmed, the blade server reboots with the latest service profile values. After the power on self-test (POST), the adapter attempts to initialize using these service profile values. If the adapter can use the values and log in to its specified target, the adapter initializes and posts an iSCSI Boot Firmware Table (iBFT) to the host memory and a valid bootable LUN to the system BIOS. The iBFT that is posted to the host memory contains the initiator and target configuration that is programmed on the primary iSCSI VNIC.


      Note


      The iBFT only uses the first iSCSI vNIC and only Target 1 for the initiator-to-target initialization. This scenario is true even if a second target (Target 2) exists for the first iSCSI vNIC.


      The next step, which is the installation of the operating system (OS), requires an OS that is iBFT capable. During installation of the OS, the OS installer scans the host memory for the iBFT table and uses the information in the iBFT to discover the boot device and create an iSCSI path to the target LUN. In some OS's a NIC driver is required to complete this path. If this step is successful, the OS installer finds the iSCSI target LUN on which to install the OS.


      Note


      The iBFT works at the OS installation software level and might not work with HBA mode (also known as TCP offload). Whether iBFT works with HBA mode depends on the OS capabilities during installation. Also, for a server that includes a Cisco UCS M51KR-B Broadcom BCM57711 adapter, the iBFT normally works at a maximum transmission unit (MTU) size of 1500, regardless of the MTU jumbo configuration. If the OS supports HBA mode, you might need to set HBA mode (also known as TCP offload), dual-fabric support, and jumbo MTU size after the iSCSI installation process.


      iSCSI Boot Guidelines and Prerequisites

      These guidelines and prerequisites must be met before configuring iSCSI boot:

      • To set up iSCSI boot from a Windows 2008 server where the second vNIC (failover vNIC) must boot from an iSCSI LUN, consult Microsoft Knowledge Base Article 976042. Microsoft has a known issue where Windows might fail to boot from an iSCSI drive or cause a bugcheck error if the networking hardware is changed. To work around this issue, follow the resolution recommended by Microsoft.
      • The storage array must be licensed for iSCSI boot and the array side LUN masking must be properly configured.
      • Two IP addresses must be determined, one for each iSCSI initiator. If possible, the IP addresses should be on the same subnet as the storage array. The IP addresses are assigned statically or dynamically using the Dynamic Host Configuration Protocol (DHCP).
      • You cannot configure boot parameters in the Global boot policy. Instead, after configuring boot parameters, you need to include the boot policy in the appropriate service profile.
      • The operating system (OS) must be iSCSI Boot Firmware Table (iBFT) compatible.
      • For Cisco UCS M51KR-B Broadcom BCM57711 network adapters:
        • Blades that use iSCSI boot must contain the Cisco UCS M51KR-B Broadcom BCM57711 network adapter. For information on installing or replacing an adapter card, see the Cisco UCS B250 Extended Memory Blade Server Installation and Service Note. The service note is accessible from the Cisco UCS B-Series Servers Documentation Roadmap at http://www.cisco.com/go/unifiedcomputing/b-series-doc.
        • Set the MAC addresses on the iSCSI device.
        • If you are using the DHCP Vendor ID (Option 43), the MAC address of an iSCSI device needs to be configured in /etc/dhcpd.conf.
        • HBA mode (also known as TCP offload) and the boot to target setting are supported. However, only Windows OS supports HBA mode during installation.
        • Before installing the OS, disable the boot to target setting in the iSCSI adapter policy, then after installing the OS, reenable the boot to target setting.

          Note


          Each time you change an adapter policy setting, the adapter reboots to apply the new setting.


        • When installing the OS on the iSCSI target, the iSCSI target must be ordered before the device where the OS image resides. For example, if you are installing the OS on the iSCSI target from a CD, the boot order should be the iSCSI target and then the CD.
        • After the server has been iSCSI booted, do not modify the Initiator Name, Target name, LUN, iSCSI device IP, or Netmask/gateway using the Broadcom tool.
        • Do not interrupt the POST (power on self-test) process or the Cisco UCS M51KR-B Broadcom BCM57711 network adapter will fail to initialize.
      • For Cisco UCS M81KR Virtual Interface Card and Cisco UCS M82-8P Virtual Interface Card:
        • Do not set MAC addresses on the iSCSI device.
        • HBA mode and the boot to target setting are not supported.
        • When installing the OS on the iSCSI target, the iSCSI target must be ordered after the device where the OS image resides. For example, if you are installing the OS on the iSCSI target from a CD, the boot order should be the CD and then the iSCSI target.
        • If you are using the DHCP Vendor ID (Option 43), the MAC address of the overlay vNIC needs to be configured in /etc/dhcpd.conf.
        • After the server has been iSCSI booted, do not modify the IP details of the overlay vNIC.
      • The VMware ESX/ESXi operating system does not support storing a core dump file to an iSCSI boot target LUN. Dump files must be written to a local disk.

      Enabling MPIO on Windows


      Note


      If you change the networking hardware, Windows may fail to boot from an iSCSI drive. For more information, see Microsoft support Article ID: 976042.


      Before You Begin

      The server on which you enable MPIO must have a Cisco VIC driver.

      Procedure
        Step 1   In the service profile associated with the server, configure the primary and secondary iSCSI vNICs.

        For more information, see Creating an iSCSI vNIC for a Service Profile.

        Step 2   Using the primary iSCSI vNIC, install the Windows operating system on the iSCSI target LUN.
        Step 3   After Windows installation is completed, use the Microsoft software iSCSI initiator to connect to the secondary iSCSI vNIC.
        Step 4   Enable MPIO on the host
        Step 5   In the service profile associated with the server, add the secondary iSCSI vNIC to the boot policy.

        For more information, see Creating an iSCSI Boot Policy.


        Configuring iSCSI Boot

        When you configure an adapter or blade in Cisco UCS to iSCSI boot from a LUN target, you need to complete all of the following steps.

        Procedure
            Command or Action Purpose
          Step 1 Configure the iSCSI boot adapter policy.  (Optional)

          For more information, see Creating an iSCSI Adapter Policy

           
          Step 2 Configure the authentication profiles to be used by the initiator and target.  (Optional)

          For more information, see Creating an Authentication Profile

           
          Step 3 If you plan to configure the iSCSI initiator to use an IP address from a pool of IP addresses, add a block of IP addresses to the iSCSI initiator pool.  (Optional)

          For more information, see Creating an iSCSI Initiator IP Pool

           
          Step 4 Create a boot policy that can be used in any service profile. Alternatively, you can create a local boot policy only for the specific service policy. However, we recommend that you create a boot policy that can be shared with multiple service profiles. 

          For more information about creating a boot policy that can be used in any service profile, see Creating an iSCSI Boot Policy.

           
          Step 5 If you created a boot policy that can be used in any service profile, you need to assign it to the service profile. Otherwise, proceed to the next step. 

          You can assign the boot policy to the service profile while configuring the iSCSI boot and vNIC parameters in the service profile in step 7.

           
          Step 6 Create an iSCSI vNIC in a service profile. 

          For more information, see Creating an iSCSI vNIC for a Service Profile

           
          Step 7 Configure the iSCSI boot parameters, including the initiator and target interfaces, and iSCSI vNIC parameters in a service profile in expert mode or service profile template. 

          For more information, see Creating a Service Profile with the Expert Wizard or Creating a Service Profile Template, respectively.

           
          Step 8 Verify the iSCSI boot operation. 

          For more information, see Verifying iSCSI Boot

           
          Step 9 Install the OS on the server. 
          For more information, see one of the following guides:
          • Cisco UCS B-Series Blade Servers VMware Installation Guide
          • Cisco UCS B-Series Blade Servers Linux Installation Guide
          • Cisco UCS B-Series Blade Servers Windows Installation Guide
           
          Step 10 Boot the server. 

           

          Creating an iSCSI Adapter Policy

          Procedure
            Step 1   In the Navigation pane, click the Servers tab.
            Step 2   On the Servers tab, expand Servers > Policies.
            Step 3   Expand the node for the organization where you want to create the policy.

            If the system does not include multitenancy, expand the root node.

            Step 4   Right-click Adapter Policies and choose Create iSCSI Adapter Policy.
            Step 5   In the Create iSCSI Adapter Policy dialog box, complete the following fields:
            Name Description

            Name field

            The name of the policy.

            This name can be between 1 and 16 alphanumeric characters. You cannot use spaces or any special characters other than - (hyphen), _ (underscore), : (colon), and . (period), and you cannot change this name after the object has been saved.

            Connection Timeout field

            The number of seconds to wait until Cisco UCS assumes that the initial login has failed and the iSCSI adapter is unavailable.

            Enter an integer between 0 and 255. If you enter 0, Cisco UCS uses the value set in the adapter firmware (default: 15 seconds).

            LUN Busy Retry Count field

            The number of times to retry the connection in case of a failure during iSCSI LUN discovery.

            Enter an integer between 0 and 60. If you enter 0, Cisco UCS uses the value set in the adapter firmware (default: 15 seconds).

            DHCP Timeout field

            The number of seconds to wait before the initiator assumes that the DHCP server is unavailable.

            Enter an integer between 60 and 300 (default: 60 seconds).

            Enable TCP Timestamp check box

            Check this box if you want to use a TCP Timestamp. With this setting, transmitted packets are given a time stamp of when the packet was sent so that the packet's round-trip time can be calculated, when needed.

            Note   

            This option only applies to servers with the Cisco UCS NIC M51KR-B adapter.

            HBA Mode check box

            Check this box to enable HBA mode.

            Important:

            This option should only be enabled for servers with the Cisco UCS NIC M51KR-B adapter running the Windows operating system.

            Boot to Target check box

            Check this box to boot from the iSCSI target.

            Note   

            This option only applies to servers with the Cisco UCS NIC M51KR-B adapter. It should be disabled until you have installed an operating system on the server.

            Step 6   Click OK.

            What to Do Next

            Include the adapter policy in a service profile and/or template.

                    Step 5   In the Create a Block of IP Addresses dialog box, complete the following fields:
                    Name Description

                    From field

                    The first IP address in the block.

                    Size field

                    The number of IP addresses in the pool.

                    Subnet Mask field

                    The subnet mask associated with the IP addresses in the block.

                    All IP addresses in the management IP pool must be in the same subnet as the IP address of the fabric interconnect.

                    Default Gateway field

                    The default gateway associated with the IP addresses in the block.

                    Step 6   Click OK.

                    What to Do Next

                    Configure one or more service profiles or service profile templates to obtain the iSCSI initiator IP address from the iSCSI initiator IP pool.

                    Deleting an iSCSI Initiator IP Pool

                    Procedure
                      Step 1   In the Navigation pane, click the LAN tab.
                      Step 2   In the LAN tab, expand LAN > Pools > Organization_Name .
                      Step 3   Expand the IP Pools (iscsi-initiator-pools) node.

                      Creating an iSCSI Boot Policy

                      You can add up to two iSCSI vNICs per boot policy. One vNIC acts as the primary iSCSI boot source, and the other acts as the secondary iSCSI boot source.

                      Procedure
                        Step 1   In the Navigation pane, click the Servers tab.
                        Step 2   On the Servers tab, expand Servers > Policies.
                        Step 3   Expand the node for the organization where you want to create the policy.

                        If the system does not include multitenancy, expand the root node.

                        Step 4   Right-click Boot Policies and choose Create Boot Policy.

                        The Create Boot Policy wizard displays.

                        Step 5   Enter a unique name and description for the policy.

                        This name can be between 1 and 16 alphanumeric characters. You cannot use spaces or any special characters other than - (hyphen), _ (underscore), : (colon), and . (period), and you cannot change this name after the object has been saved.

                        Step 6   (Optional)To reboot all servers that use this boot policy after you make changes to the boot order, check the Reboot on Boot Order Change check box.

                        In the Cisco UCS Manager GUI, if the Reboot on Boot Order Change check box is checked for a boot policy, and if CD-ROM or Floppy is the last device in the boot order, deleting or adding the device does not directly affect the boot order and the server does not reboot.

                        Step 7   (Optional)If desired, check the Enforce vNIC/vHBA/iSCSI Name check box.
                        • If checked, Cisco UCS Manager displays a configuration error and reports whether one or more of the vNICs, vHBAs, or iSCSI vNICs listed in the Boot Order table match the server configuration in the service profile.
                        • If not checked, Cisco UCS Manager uses the vNICs, vHBAs, or iSCSI vNICs (as appropriate for the boot option) from the server configuration in the service profile. It does not report whether the vNICs, vHBAs, or iSCSI vNICs specified in the boot policy match the server configuration in the service profile.
                        Step 8   To add a iSCSI boot to the boot policy, do the following:
                        1. Click the down arrows to expand the iSCSI vNICs area.
                        2. Click the Add iSCSI Boot link.
                        3. In the Add iSCSI Boot dialog box, enter a name for the iSCSI vNIC, and click OK.
                        4. Repeat steps b and c to create another iSCSI vNIC.

                        What to Do Next

                        Include the boot policy in a service profile and/or template.

                        After a server is associated with a service profile that includes this boot policy, you can verify the actual boot order in the Boot Order Details area on the General tab for the server.

                                      Deleting an IQN Pool

                                      If you delete a pool, Cisco UCS Manager does not reallocate any addresses from that pool that have been assigned to vNICs or vHBAs. All assigned addresses from a deleted pool remain with the vNIC or vHBA to which they are assigned until one of the following occurs:

                                      • The associated service profiles are deleted.
                                      • The vNIC or vHBA to which the address is assigned is deleted.
                                      • The vNIC or vHBA is assigned to a different pool.
                                      Procedure
                                        Step 1   In the Navigation pane, click the SAN tab.
                                        Step 2   On the SAN tab, expand SAN > Pools.
                                        Step 3   Expand the node for the organization containing the pool.

                                        If the system does not include multitenancy, expand the root node.

                                        Step 4   Expand the IQN Pools node.
                                        Step 5   Right-click the pool you want to delete and select Delete.
                                        Step 6   If the Cisco UCS Manager GUI displays a confirmation dialog box, click Yes.

                                        LAN Boot

                                        You can configure a boot policy to boot one or more servers from a centralized provisioning server on the LAN. A LAN (or PXE) boot is frequently used to install operating systems on a server from that LAN server.

                                        You can add more than one type of boot device to a LAN boot policy. For example, you could add a local disk or virtual media boot as a secondary boot device.

                                        Configuring a LAN Boot for a Boot Policy

                                        You can also create a local boot policy that is restricted to a service profile or service profile template. However, except for iSCSI boot, we recommend that you create a global boot policy that can be included in multiple service profiles or service profile templates.

                                        You can add more than one type of boot device to a boot policy. For example, you could add a local disk or virtual media boot as a secondary boot device.

                                        This procedure continues directly from Creating a Boot Policy.

                                        Procedure
                                          Step 1   Click the down arrows to expand the vNICs area.
                                          Step 2   Click the Add LAN Boot link.
                                          Step 3   In the Add LAN Boot dialog box, enter the name of the vNIC that you want to use for the LAN boot in the vNIC field, then click OK.
                                          Step 4   Do one of the following:
                                          • Add another boot device to the Boot Order table.
                                          • Click OK to finish.

                                          What to Do Next

                                          Include the boot policy in a service profile and/or template.

                                          After a server is associated with a service profile that includes this boot policy, you can verify the actual boot order in the Boot Order Details area on the General tab for the server.

                                          Local Disk Boot

                                          If a server has a local drive, you can configure a boot policy to boot the server from that drive.


                                          Note


                                          Cisco UCS Manager does not differentiate between the types of local drives. If an operating system has been installed on more than one local drive or on an internal USB drive (eUSB), you cannot specify which of these local drives the server should use as the boot drive.


                                          Configuring a Local Disk Boot for a Boot Policy

                                          You can also create a local boot policy that is restricted to a service profile or service profile template. However, except for iSCSI boot, we recommend that you create a global boot policy that can be included in multiple service profiles or service profile templates.

                                          You can add more than one type of boot device to a boot policy. For example, you could add a virtual media boot as a secondary boot device.

                                          This procedure continues directly from Creating a Boot Policy.

                                          Procedure
                                            Step 1   Click the down arrows to expand the Local Devices area.
                                            Step 2   Click Add Local Disk to add the device to the Boot Order table.
                                            Step 3   Do one of the following:
                                            • Add another boot device to the Boot Order table.
                                            • Click OK to finish.

                                            What to Do Next

                                            Include the boot policy in a service profile and/or template.

                                            After a server is associated with a service profile that includes this boot policy, you can verify the actual boot order in the Boot Order Details area on the General tab for the server.

                                            Virtual Media Boot

                                            You can configure a boot policy to boot one or more servers from a virtual media device that is accessible from the server. A virtual media device mimics the insertion of a physical CD-ROM disk (read-only) or floppy disk (read-write) into a server. This type of server boot is typically used to manually install operating systems on a server.

                                            Configuring a Virtual Media Boot for a Boot Policy

                                            You can also create a local boot policy that is restricted to a service profile or service profile template. However, except for iSCSI boot, we recommend that you create a global boot policy that can be included in multiple service profiles or service profile templates.

                                            You can add more than one type of boot device to a boot policy. For example, you could add a local disk boot as a secondary boot device.


                                            Note


                                            Virtual Media requires the USB to be enabled. If you modify the BIOS settings that affect the USB functionality, you also affect the Virtual Media. Therefore, we recommend that you leave the following USB BIOS defaults for best performance:

                                            • Make Device Non Bootable—set to disabled
                                            • USB Idle Power Optimizing Setting—set to high-performance

                                            This procedure continues directly from Creating a Boot Policy.

                                            Procedure
                                              Step 1   Click the down arrows to expand the Local Devices area.
                                              Step 2   Click one of the following links to add the device to the Boot Order table:
                                              • Add CD-ROM
                                              • Add Floppy
                                              Step 3   Do one of the following:
                                              • Add another boot device to the Boot Order table.
                                              • Click OK to finish.

                                              What to Do Next

                                              Include the boot policy in a service profile and/or template.

                                              After a server is associated with a service profile that includes this boot policy, you can verify the actual boot order in the Boot Order Details area on the General tab for the server.
