Replacing the disk drives

Removing, adding, or installing disks in a single-disk C1200

Considerations for replacing or adding a disk to a C1200  Top

The procedures for removing, replacing, or adding a disk drive to a C1200 system depend on how many drives are currently in the system. For example, if you are replacing or adding a disk to a C1200 that has two or more disks, it can be done without shutting down the system. If you are replacing a disk in a single-disk system, the system must be shut down and the replacement process must be treated as if the C1200 system were being installed for the first time.

Replacing or adding a disk in a C1200 system consists of the following procedures:
