shutdown
Description Shuts down the Storage Controller in a controller module. This ensures that a proper failover sequence is
used, which includes stopping all I/O operations and writing any data in write cache to disk.
CAUTION: Performing a shut down will cause data to be unavailable from the Storage
Controller that is shut down. If the Storage Controller in each controller module is shut down,
hosts cannot access the system’s data.

suspend replication-set
Description
Suspends the replication operations for the specified replication set. This command applies to virtual storage
only. You can run this command on the replication set’s primary system.
When you run this command, all replications in progress are paused and no new replications are allowed to
start. During the suspension period, you can abort paused replications using the abort replication command.
After you suspend replication, you must resume it using the resume replication-set command to allow the
replication set to resume replications that were in progress and allow new replications to start.
If replications are attempted during the suspended period (including scheduled replications), the replications
will fail.
