• The RAID Manager command (pairdisplay) failed, indicating that the issue is on the RAID Manager side, rather than SRM or VMware configurations.

 

Resolution

It is recommended that customers direct any SRA issues to the SRA vendor for their initial investigation, as per Broadcom SRA troubleshooting policy.
