Replacing a disk
The correct procedure for replacing a disk in a storage system depends upon a number of factors,
including the RAID configuration, the data protection level of volumes and snapshots, and the
number of disks being replaced. Replacing a disk in a storage system that is in a cluster requires
rebuilding data on the replaced disk.
Replacing a disk in a storage system includes the following basic steps.
• Planning for rebuilding data on either the disk or the entire storage system (all storage systems)
• Powering the disk off in the CMC (non-hot-swap storage systems)
• Physically replacing the disk in the storage system (all storage systems)
