rescan
When installing a system with drive enclosures attached, the enclosure IDs might
not agree with the physical cabling order. This is because the controller might have
been previously attached to some of the same enclosures and it attempts to preserve
the previous enclosure IDs if possible. To correct this condition, make sure that both
controllers are up and perform a rescan using the CLI.
For details see the CLI reference guide.
reset host-channel-link
Issues a loop initialization primitive (LIP) from specified controllers on specified
channels. This command is for use with an FC system using FC-AL (loop) topology.

restart
Restarts the RAID controller or the Management Controller in either or both
controller modules.
If you restart a RAID controller, it attempts to shut down with a proper failover
sequence, which includes stopping all I/O operations and flushing the write cache to
disk, and then the controller restarts. The Management Controllers are not restarted
so they can provide status information to external interfaces.
If you restart a Management Controller, communication with it is temporarily lost
until it successfully restarts. If the restart fails, the partner Management Controller
remains active with full ownership of operations and configuration information.
Caution –
