## Suspending and Resuming the Configured Disk

Restore operation mainly requires suspend and resume operations.
These operations are used in Disk Key Replication. There are some limitations for Disk Key Replication. For more information see, “SME Disk Key Replication”.

Caution Suspending a disk results in SME rejecting all the I/Os issued by the host. If you suspend a disk that is being actively used by a host, application I/O failures can occur. We recommend that the applications using this disk be quiesced, or failover to an alternate disk before suspending the disk.
