Checking Firmware Version Consistency

An independent 6 Gbit/s SAS interface card is used. Use CLI commands to power on and off the interface card for recovery.

Operation Restriction

You can only power on and off the 6 Gbit/s SAS interface card when the disk enclosure and the RAID group are normal and have no alarms. The check includes but is not limited to the following:
Physical disk status, logical status of disks, expansion module status, enclosure status, RAID group status, whether the system has single links, disk fault, RAID group degradation, and RAID group faults.
Before powering on and off the interface card, ensure that services on all the ports of the card are stopped.
To recover multiple 6 Gbit/s SAS interface cards, you can only power off one card each time and then power on the card. After the card passes the check mentioned above, you can power on and then off the second card.
