fc srp initiator

To configure an initiator— normally a SAN-attached host but in IB terms a SRP host combined with a Server Switch—to communicate with a Fibre Channel SAN across a Fibre Channel gateway on your Server Switch, enter the fc srp initiator command in Global Configuration mode. To deny SAN access to the SRP host, to delete an initiator from the running configuration, or to reconfigure the description of the initiator to an empty string, use the no form of this command.

fc srp initiator guid extension {auto-bind | bootup target target-wwpn lu logical-unit | description descr | discover-itl | pkey pkey-value | wwnn wwnn-value}

no fc srp initiator guid extension [description]

Syntax Description

guid

Global unique identifier (GUID) of the SRP host.

Note The GUID of your SRP host appears printed on the HCA in your server, and you can use host driver utilities to view the GUID. For more information, refer to the Host Channel Adapter Installation Guide.

extension

GUID extension of the SRP host.

auto-bind

1. Creates the initiator entry in the configuration file and binds the host to a world-wide node name (WWNN) that your Server Switch generates internally to uniquely identify the host.

2. Creates virtual ports for this initiator on every possible physical FC gateway port on your Server Switch. FC devices use these virtual ports to communicate with the initiator.

bootup

Configures the SRP host to boot from a Fibre Channel logical unit (LU).

target

Specifies the world-wide port name (WWPN) of the port of the FC storage device that stores image that you want the initiator to boot.

target-wwpn

WWPN of the port of the FC storage device that stores image that you want the initiator to boot.

lu

Specifies the logical unit (LU) that stores image that you want the initiator to boot.

logical-unit

Logical ID of the LU that stores image that you want the initiator to boot.

description

(Optional) Assigns an alphanumeric ASCII description string to the initiator.

descr

Alphanumeric ASCII description string to assign to the initiator.

discover-itl

Discovers initiator-target-LUN (ITL) combinations and adds them to your configuration file. Targets refer to SAN storage devices, and LUNs refer to the logical units within SAN storage devices.

pkey

Assigns a partition key (P_key) to the initiator.

Note Your Server Switch does not currently support partition keys for SRP.

pkey-value

16-bit partition key to assign to the initiator. Assign multiple partition keys by appending a colon, then the next key (aa:aa:bb:bb:cc:cc:dd:dd).

wwnn

Creates the initiator entry in the configuration file and assigns a manually-entered WWNN to the initiator.

wwnn-value

WWNN to assign to the initiator.

Defaults

By default, no P_keys apply to initiators. By default, global policies apply to initiators. Configure global policies with fc srp-global commands.

Command Modes

Global Configuration (config) mode.

Usage Guidelines

Platform Availability:

Cisco SFS 3001, Cisco SFS 3012

Privilege Level:

Unrestricted read-write user, Fibre Channel read-write user

Configure initiators so SRP hosts can communicate with SANs.

Note When you configure new initiators, those initiators inherit the global policies that exist at that time. When you change global policies, the new global policies do not apply to existing initiators.

Before you can customize an initiator, you must create an initiator entry with the auto-bind keyword or the wwnn keyword. Once you identify a host as an initiator, you can customize the initiator with the remaining keywords.

Command Keyword Usage Guidelines:

•auto-bind

You must create initiators and assign, or bind, a WWNN (an identifier that FC devices recognize) to each initiator so that FC devices can communicate with initiators. When you use the auto-bind keyword to create an initiator and generate a WWNN for an initiator, your Server Switch creates a virtual port (NL_Port) that represents the initiator on every physical port on the FC gateway. Your Server Switch assigns an internally-generated WWPN to each virtual port. Each physical port on the FC gateway supports 32 virtual ports to form a virtual FC arbitrated loop.

Note We strongly recommend that you use the auto-bind keyword to assign WWNNs to initiators as you configure the initiators. If you perform a manual configuration, you may create duplicate WWNNs that create traffic conflicts.

•description

Enter a description to help identify an initiator without reading its GUID and extension.

•discover-itl

Discover ITLs to add all available initiator-target-LUN (ITL) groups to the running configuration. For detailed information on ITLs, refer to the Fibre Channel Gateway User Guide.

•pkey

Refer to the Element Manager User Guide to learn more about partitions.

•wwnn

When you enter a question mark (?) after the wwnn keyword, the CLI provides a recommended WWNN value.

Examples

The following example adds an initiator to the running configuration and automatically configures the WWNN of the initiator and the WWPNs of the virtual ports that point to the initiator from the physical FC gateway ports.
SFS-7000P(config)# fc srp initiator 00:00:2C:90:01:1b:b7:50 00:00:00:00:00:00:00:00 
auto-bind
The following example assigns the description InfiniBand Host to an existing initiator. The name now appears in the show fc srp initiator command output.
SFS-7000P(config)# fc srp initiator 00:00:2C:90:01:1b:b7:50 00:00:00:00:00:00:00:00 
description "InfiniBand Host"
The following example discovers all potential initiator-target-LUN (ITL) combinations that your Server Switch can support and adds them to the running configuration. To view the results of this command, enter the show fc srp itl command.
SFS-7000P(config)# fc srp initiator 00:00:2C:90:01:1b:b7:50 00:00:00:00:00:00:00:00

fc srp initiator-wwpn

To manually create, on a physical FC gateway port, a virtual port that points to an initiator, enter the fc srp initiator-wwpn command in Global Configuration mode.

fc srp initiator-wwpn guid extension slot#/port# wwpn

Syntax Description

guid

Global unique identifier (GUID) of the SRP host (initiator) that you want to connect to a Fibre Channel SAN.

extension

GUID extension of the SRP host that you want to connect to a Fibre Channel SAN.

slot#

Slot of the FC gateway expansion module that you want to use.

port#

Fibre Channel gateway port that you want to use to connect your initiator to the SAN.

wwpn

WWPN to assign to the new virtual port.

Defaults

This command has no default settings.

Command Modes

Global Configuration (config) mode.

Usage Guidelines

Platform Availability:

Cisco SFS 3001, Cisco SFS 3012

Privilege Level:

Unrestricted read-write user or Fibre Channel read-write user.

Configure WWPNs for initiators so that FC devices can recognize them and communicate with them. With virtual ports (NL_ports), physical FC ports can point to multiple initiators, and multiple ports can point to the same initiator. For instance, if you have Initiators X and Y and Physical FC Ports A and B, you can create the following virtual ports:

•virtual port AX on port A that points to initiator X

•virtual port AY on port A that points to initiator Y

•virtual port BX on port B that points to initiator X

•virtual port BY on port B that points to initiator Y

As you can see, in this way, multiple virtual ports can point to one initiator and individual physical ports can support multiple initiators.

When you enter a question mark (?) after the port# variable, the CLI provides a suggested WWPN value.

Note Use the recommended WWPN unless you have a compelling reason to do otherwise. We strongly recommend that you use the fc srp initiator command with the auto-bind keyword to create initiator entries and assign WWPNs to initiators.

Examples

The following example uses the online help (?) to find the recommended WWPN value, then configures a virtual port on port 1 on the FC gateway expansion module in slot 7.
SFS-7000P(config)# fc srp initiator-wwpn 00:00:2c:90:01:1b:b7:50 00:00:00:00:00:00:00:00

fc srp it

To configure an initiator-target (IT) pair—a fully-configured link between an initiator and a target storage device port—with your Server Switch, enter the fc srp it command in Global Configuration mode. To delete or reconfigure an IT pair entry from the configuration file, use the no form of this command.

fc srp it guid extension wwpn {description "descr" | discover-itl | gateway-portmask-policy {default | test-mode | restricted port-selection}}

no fc srp it guid extension wwpn [test-mode | gateway-portmask-policy restricted port-selection]

Syntax Description

guid

Global unique identifier (GUID) of the initiator.

extension

GUID extension of the initiator.

wwpn

World-wide port name (WWPN) of the target port of the FC storage device.

description

Assigns a description to the initiator-target pair.

descr

Alphanumeric description to assign to the initiator target.

discover-itl

Discovers initiator-target-LUN (ITL) groups for the specified target and adds them to the configuration file. For detailed information on ITLs, refer to the Fibre Channel Gateway User Guide.

gateway-portmask-policy

(Optional) Designates the physical FC gateway ports that the initiator can use to access the storage port. When you add FC gateway ports to the policy, the initiator cannot use those ports to access the storage. When you use the no keyword to remove FC gateway ports from the policy, the initiator can access the storage through those ports.

default

Assigns the global gateway portmask policy to the IT. To view your default policy, enter the show fc srp-global command (in User Exec mode or Privileged Exec mode) and view the default-gateway-portmask-policy field.

restricted

(Optional) Denies the initiator access to the ports that you specify with the port-selection variable. Use the no form of the command to add ports to the policy to grant the initiator access.

port-selection

(Optional) Port, list of ports, or range of ports to which you grant or deny the initiator access.

test-mode

(Optional) Sets an inactive initiator-target pairing to test mode, which configures the FC gateway to log in to storage persistently and block log-ins from SRP hosts (initiators). Use test mode as you set up your Fibre Channel connections, then use the no form of the command to return to normal mode.

Note You cannot configure an active IT to test mode. Active ITs must remain in normal mode.

Note A test-mode configuration does not persist across reboots.

Defaults

By default, this policy denies initiators access to all targets.

Command Modes

Global Configuration (config) mode.

Usage Guidelines

Platform Availability:

Cisco SFS 3001, Cisco SFS 3012

Privilege Level:

Unrestricted read-write user or Fibre Channel read-write user.

The fc srp it command sets policies that control the extent to which the initiator accesses Fibre Channel gateway ports. Use the no form of this command with the gateway-portmask-policy keyword to grant an initiator access to the ports you specify.

Note We strongly recommends that you let your Server Switch populate the running configuration with IT pairs; do not manually enter IT pairs.

Examples

The following example assigns a description of entry to an existing IT:

Usage Guidelines

Platform Availability:

Cisco SFS 3001, Cisco SFS 3012

Privilege Level:

Unrestricted read-write user or Fibre Channel read-write user.

The fc srp itl command configures new ITLs and sets policies to control access that the SCSI RDMA Protocol (SRP) initiator has to the Fibre Channel storage devices on a per-lun basis. An "initiator-target-lun" (ITL) identifies a fully-configured link between an initiator and storage.

Once an ITL entry is created, the gateway-portmask-policy setting is independent of its IT entry. You may change the setting on a per ITL basis. However, a port is accessible for an ITL only when the port is accessible for both the IT and ITL entries.

The port list specified in this command creates an accumulative effect to the actual gateway-portmask-policy. For example, if your current mask is 2/1 and 2/2, after a command of "config fc srp itl gateway-portmask-policy restricted 2/1" the result of the mask for this itl would be "2/2." The same effect applies to the no-command for gateway-portmask-policy.

We recommend that you create ITLs with the discover-itl keyword in the CLI or the Discover LUNs button in Element Manager.

Usage Guidelines

Platform Availability:

Cisco SFS 3001, Cisco SFS 3012

Privilege Level:

Unrestricted read-write user or Fibre Channel read-write user.

Use the fc srp lu command to configure LU attributes.

We recommend that you do not manually create LUs. We recommend that you let your gateway card(s) detect LUs. The gateway card automatically creates LU entries when it discovers LUs.

For the following settings, the LU entry gets the default from srp-global settings at entry creation time depending on the LU category.

Once a LU entry is created, the LU settings are independent of the srp-global. You may change the settings on a per LU basis using this command.

Table 3-2 provides usage guidelines for this command.

Table 3-2 Usage Guidelines for fc srp lu Command Arguments

Argument

Description

dynamic-gateway-port-failover

Default : the configured value of srp-global itl for this LU category(random/sequential).

Allows the controller to select an alternate gateway interface port if the primary path fails. Enter the fc srp lu command with this keyword to enable this feature. Otherwise, use the no form of the command string to disable this feature. If you enable this policy, you implicitly disable port load balancing and dynamic path affinity.

dynamic-gateway-port-loadbalancing

Default : the configured value of srp-global itl for this LU category(random/sequential).

Allows data to be sent between the initiator and Fibre Channel target using all available ports on the gateway interface. Port selection relies upon comparative IO traffic. The controller attempts to distribute traffic equally between the ports. Enter the fc srp lu command with this keyword to enable this feature. Otherwise, user the no form of the command string to disable this feature. If you enable this policy, you implicitly disable port failover and dynamic path affinity.

dynamic-path-affinity

Default : the configured value of srp-global itl for this LU category(random/sequential).

Allows the system to maintain a preference for a specific path. If the number of outstanding I/Os becomes excessive, or the path fails, the gateway uses an alternate path. When enabled, the gateway uses the current path until the path condition changes. Note that frequent switching degrades performance. Enter the fc srp lu command with this keyword to enable this feature. Otherwise, use the no form of the command string to disable this feature. If you enable this policy, you implicitly disable port failover and port loadbalancing.

io-hi-mark mark

Default : the configured value of srp-global itl for this LU category(random/sequential).

Sets the maximum number of I/O requests that can be sent per logical unit. The value, an integer, must fall between 1 and 256. Enter the fc srp lu command with this keyword and the desired io-hi-mark value to set this feature.

max-retry retry

Default: the configured value of the srp-global itl for this LU category(random/sequential).

Number of times the same I/O request may be sent to a logical unit. Increase the value if heavy traffic runs, or increase the min-io-timeout value. The value, an integer, must fall between 1 and 100. Enter the fc srp lu command with this keyword and the desired max-retry value to set this feature. - min-io-timeout timeout Default: the configured value of srp-global itl for this LU category(random/sequential).

Maximum amount of time allowed for I/O traffic to be accepted by a logical unit. Increase this value (or increase the max-retry value) if you use a known slow connection. The value, an integer, must fall between 1 and 1800.

target target-wwpn

Specifies a target to add to the LU target list. The LU can be accessed via the target ports configured. You can add at most eight targets to a LU one at a time. Enter the fc srp lu command with this keyword and the desired world-wide port name (WWPN) of the target port value to add the target port to the list. Use the no form of this command to remove a target port from the list.

Examples

The following example assigns a name to more easily identify the LU.

Policy

Description

sequential

(Optional) Configures SRP global defaults for LUs of sequential access devices. Without this keyword, the configuration will be for the global defaults for LUs of random access devices.

dynamic-gateway-port-failover

SRP global defaults for LUs of random/sequential access devices.

Default for random devices: false
Default for sequential devices: true

This value is applied to LU entries as their default setting at entry creation time. You can overwrite the value on LU basis later.

Allows the controller to select an alternate gateway interface port if the primary path fails. Enter the fc srp-global itl command with this keyword to enable this feature. Otherwise, include the no keyword at the beginning of the command string to disable this feature. If you enable this policy, you implicitly disable port load balancing and dynamic path affinity.

dynamic-gateway-port-loadbalancing

SRP global defaults for LUs of random/sequential access devices.

Default for random devices: true
Default for sequential devices: false

This value is applied to LU entries as their default setting at entry creation time. You can overwrite the value on LU basis later.

Allows data to be sent between the initiator and Fibre Channel target using all available ports on the gateway interface. Port selection relies upon comparative IO traffic. The controller attempts to distribute traffic equally between the ports. Enter the fc srp-global itl command with this keyword to enable this feature. Otherwise, include the no keyword at the beginning of the command string to disable this feature. If you enable this policy, you implicitly disable port failover and dynamic path affinity.

dynamic-path-affinity

SRP global defaults for LUs of random/sequential access devices.

Default for random devices: false
Default for sequential devices: false

This value is applied to LU entries as their default setting at entry creation time. You can overwrite the value on LU basis later.

Allows the system to maintain a preference for a specific path. If the number of outstanding I/Os becomes excessive, or the path fails, the gateway uses an alternate path. When enabled, the gateway uses the current path until the path condition changes.

Note Frequent switching degrades performance.

Enter the fc srp-global itl command with this keyword to enable this feature. Otherwise, include the no keyword at the beginning of the command string to disable this feature. If you enable this policy, you implicitly disable port failover and port loadbalancing.

io-hi-mark mark

SRP global defaults for LUs of random/sequential access devices.

Default for random devices: 16
Default for sequential devices: 1

This value is applied to LU entries as their default setting at entry creation time. You can overwrite the value on LU basis later.

Sets the maximum number of I/O requests that can be sent per logical unit. The value, an integer, must fall between 1 and 256. The hi mark defaults to 16. Enter the fc srp-global itl command with this keyword and the desired io-hi-mark value to set this feature.

max-retry retry

SRP global defaults for LUs of random/sequential access devices.

Default for random devices: 5
Default for sequential devices: 1

This value is applied to LU entries as their default setting at entry creation time. You can overwrite the value on LU basis later.

Number of times the same I/O request may be sent to a logical unit. Increase the value if heavy traffic runs, or increase the min-io-timeout value. The value, an integer, must fall between 1 and 100. The retry value defaults to 5. Enter the fc srp-global itl command with this keyword and the desired max-retry value to set this feature.

min-io-timeout timeout

SRP global defaults for LUs of random/sequential access devices.

Default for random devices: 10
Default for sequential devices: 60

This value is applied to LU entries as their default setting at entry creation time. You can overwrite the value on LU basis later.

Maximum amount of time allowed for I/O traffic to be accepted by a logical unit. Increase this value (or increase the max-retry value) if you use a known slow connection. The value, an integer, must fall between 1 and 1800. The timeout defaults to 10 seconds.

Examples

The following example sets the I/O high mark of the ITL to 32.
SFS-7000P(config)fc srp itl 00:05:ad:00:00:01:29:c5 00:00:00:00:00:00:00:00

Usage Guidelines

Platform Availability:

Cisco SFS 3001, Cisco SFS 3012

Privilege Level:

Unrestricted read-write user or Fibre Channel read-write user.

Enable global LUN masking to deny LUN access to new initiators so that they cannot communicate with SAN nodes until you grant them access on an individual basis. Disable LUN masking to grant new ITLs immediate access to all LUNs.

Note An initiator requires both port and LUN access before it can successfully access a LUN. To grant port access, use the fc srp-global gateway-portmask-policy restricted, fc srp it and fc srp itl commands.

Note Policies only apply to ITs and ITLs that you create after you configure the policies.
