restart fails, the partner Management Controller remains active with full ownership of operations and
configuration information.

[a|b|both]
[noprompt]
Parameters
[a|b|both]
Optional. The controller module containing the controller to restart. If this parameter is omitted, the command
affects the controller being accessed.
[noprompt]
Optional. Suppresses confirmation prompts. Specifying this parameter allows the command to proceed
without user interaction.
Output Messages are displayed when the controller shut down, when failover is initiated, and when the controller has
restarted.
Examples Restart the Management Controller in controller A, to which you are logged in.

Description
Restarts the Storage Controller in a controller module.
When you restart a Storage 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 Storage Controller
restarts. Restarting a Storage Controller restarts the corresponding Management Controller.
CAUTION:
• Depending on the mapping configuration, restarting one Storage Controller may cause loss
of access to data.
• If you restart both Storage Controllers, all hosts will lose access to the system and its data
until the restart is complete. Additionally, both Management Controllers will be restarted
and all users’ sessions will need to be restarted.
NOTE: When a Storage Controller is restarted, live performance statistics that it recorded will
be reset. Historical performance statistics are not affected. In a dual-controller system, disk
statistics may be reduced but will not be reset to zero, because disk statistics are summed
