restart sc
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:
If you restart both Storage Controllers, both Management Controllers will also be
restarted so all hosts and users will lose access to the system and its data until the restart is complete.
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 between the two
controllers. For more information, see help for commands that show statistics.

Syntax
restart sc
[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 in console format; required for XML API format. Suppresses the confirmation prompt, which
requires a yes or no response. Specifying this parameter allows the command to proceed without
user interaction.
sc|mc
The controller to restart:
•
sc
: Storage Controller
•
mc
: Management Controller
Output
Messages are displayed when the controller shut down, when failover is initiated, and when the
controller has restarted.
Example
From controller A, restart the Storage Controller in controller B.
# restart sc b
Restart both Storage Controllers.
# restart sc both
While the specified Storage Controllers restart, communication will temporarily
be lost with the corresponding Management Controllers.
Restarting both controllers can cause a temporary loss of data availability.
Do you want to continue? (y/n)
yes
