Managing Chassis and Dynamic Storage

This chapter includes the following sections:

Chassis Summary

Viewing Chassis Summary

By default when you log on to the Cisco UCS C-Series rack-mount server, the Summary pane of the Chassis is displayed in the Web UI. You can also view the Chassis summary when in another tab or working area, by completing the following steps:

Procedure
    Step 1   In the Navigation pane, click the Chassis menu.
    Step 2   In the Chassis menu, click Summary.
    Step 3   In the Chassis Properties area of the Chassis Summary pane, review the following information:
    Name Description

    Product Name field

    The model name of the chassis.

    Serial Number field

    The serial number for the chassis.

    PID field

    The product ID.

    Description field

    A user-defined description for the server.

    Step 4   In the Cisco IMC Information area of the Chassis Summary pane, review the following information:
    Name Description

    Hostname field

    A user-defined hostname for the Cisco IMC. By default, the hostname appears in CXXX-YYYYYY format, where XXX is the model number and YYYYYY is the serial number of the server.

    Management IP Address field

    The management IP address for the Cisco IMC.

    Timezone field

    Displays the chosen time zone.

    Current Time field

    The current date and time according to the Cisco IMC clock.

    Note   

    Cisco IMC gets the current date and time from the server BIOS when the NTP is disabled. When NTP is enabled, BIOS and Cisco IMC gets the current time and date from the NTP server. To change this information, reboot the server and press F2 when prompted to access the BIOS configuration menu. Then change the date or time using the options on the main BIOS configuration tab.

          Dynamic Storage

          Dynamic Storage Support

          Effective with this release, The Cisco UCS C-Series rack-mount servers support dynamic storage of Serial Attached SCSI (SAS) drives in the Cisco Management Controller (CMC). This dynamic storage support is provided by the SAS fabric manager located in the CMC.

          The fabric manager interacts with the PMC SAS expanders over an Out-of-Band ethernet connection. SAS Expanders allow you to maximize the storage capability of an SAS controller card. Using these expanders, you can employ SAS controllers support up to 60 hard drives. In CMC, an active SIOC configures the expander zoning, where you can assign the drives to the server nodes through the Web UI, command line interface or Cisco UCS Manager. The standby CMC is updated with the current state, so during a CMC fail-over standby, the CMC can take over the zoning responsibilities. Once the drives are visible to a particular server node, you can manage these using RAID controller.


          Note
          The SAS controller support 56 hard disk drives (HDD) by default. There is also a provision to to replace Server node 2 with an additional four HDDs on Server 2. In that case the total number of HDDs shown in the Zoning page is 60. However, CMC would not support zoning for the additional HDDs 57, 58, 59, 60.

          The SAS fabric manager provides an API library for other processes to configure and monitor the expanders and drives. Configuration of the fabric involves zoning the drives, updating the firmware for expanders and drives.

          Dynamic Storage supports the following options:

          • Assigning physical disks to server 1 and server 2

          • Chassis Wide Hot Spare (supported only on RAID controllers)

          • Shared mode (supported only in HBAs)

          • Unassigning physical disks

          Viewing SAS Expander Properties

          Procedure

            Step 2   In the Chassis menu, click Inventory.
            Step 3   In the Inventory working area, click the Dynamic Storage tab.
            Step 4   In the SAS Expander tab, review the following high level details for SAS Expanders:
            Name Description

            ID column

            The product ID of the expander.

            Name column

            The name of the expander.

            Firmware Version column

            The firmware version the expander uses.

            Secondary Firmware Version column

            The secondary firmware version of the expander.

            Hardware Revision column

            The hardware version of the expander.

            SAS Address column

            The SAS address of the expander.

            Server Up Link Speed column

            Up link speed received with the LSI RAID Controller.

            Note   

            This is available only on some C-Series servers.

            Note   

            You can view up to four speed levels for Server 1 and 2 respectively using the Filter icon on the top right hand corner of the SAS Expander table. Select the Tick mark next to the speed filter to view the individual speed in the table.

            Assigning Physical Drives to Servers

            You can assign a physical drive to Server 1 or Server 2, or both, based on your requirements. On the Web UI the Chassis Front View area displays the physical drives available on the chassis. You can choose a physical drive individually or an entire row of physical drives by checking the checkbox against the drives.

            Before You Begin

            You must log in with user or admin privileges to perform this task.

            Procedure
              Step 1   In the Navigation pane, click the Chassis menu.
              Step 2   In the Chassis menu, click Inventory.
              Step 3   In the Inventory working area, click the Zoning tab.

              The Chassis Front View is displayed.

              Step 7   To assign the physical drive or drives to both servers, click the Share link.

              A prompt appears informing that the physical drives would be assigned to both servers.

              Step 8   Click OK to confirm.
              Note   

              Shared mode is supported only for HBAs.

              What to Do Next

              Move a physical drive as chassis wide hot spare, share, or unassign servers.

              Moving Physical Drives as Chassis Wide Hot Spare

              You can move the selected physical drive as a chassis wide hot spare. On the Web UI the Chassis Front View area displays the physical drives available on the chassis. You can choose a physical drive individually or an entire row of physical drives by checking the checkbox against the drives.

              Note

              Chassis wide hot spare is supported only in Mezz RAID controllers (RAID Controller for UCS C3X60 storage). This option is unavailable if the chassis has an HBA card.
