Description (partial)

After upgrading/downgrading firmware to NX-OS 4.2(5) or 4.2(6) scsi flows configured for the SSM module are not working.

Can not enable SSM feature "scsi-flow".

Switch(config)# ssm enable feature ?
    dmm        ILC application
    invista    ILC application
    nsp        ILC application
    santap     ILC application
    scsi-flow  ILC application <<<<< missing
    se         ILC application

Checking the configuration, the following was found.

ssm enable feature (null) module 1 <<< ( null should be scsi-flow )

scsi-flow flow-id 501 initiator-vsan 500 initiator-pwwn <pwwn1>  target-vsan 500 target-pwwn <pwwn2> 
scsi-flow flow-id 501 write-acceleration
This applies to a Storage Services Module ( DS-X9032-SSM ).
In the above example, module 1 is an SSM.

The feature "scsi-flow" was accidentally removed from the firmware at NX-OS 4.2(5),
as the feature is being deprecated in NX-OS 5.0.
