Configuration notes for provisioning of 7210 SAS-R6 IMMv2 (IMM-b) cards

The 7210 SAS-R6 platform supports IMM version-2 cards (imm-sas-b variants). To use IMMv2 cards, you must provision the chassis using the config>system>chassis>allow-imm-family CLI command as shown below. This command allows the software know which version of cards will be used in the system and allows it to initialize the system appropriately with the correct set of parameters. A change to this value requires a reboot of the chassis.

 config>system>chassis#
         allow-imm-family imm-family

where:

imm-family = imm-sas-r-b | imm-sas-r-c

For the list of IMMs supported in a particular release, see the release notes.

The user can change the value of allow-imm-family at any time. It does not change the operational state of the chassis. For the value to take effect, the user must reboot. If the software detects a mismatch in the cards specified by allow-imm-family and the IMM cards provisioned/equipped in the chassis, it will generate an error as shown below.


*A:NS140500018# /configure system chassis allow-imm-family ?
  - allow-imm-family <imm-family>
  - no allow-imm-family

<imm-family>         : imm-sas-r-b|imm-sas-r-c
*A:NS140500018# /configure system chassis allow-imm-family imm-sas-r-b 
INFO: CHMGR #4004 Configuration changes successful. Reboot the chassis for configura
tion to take effect.

Use the following command to display a list of supported cards per family.

*A:sasr_dutb>show>system# chassis imm-family all
