Other maintenance actions



Transferring the memory unit to a new drive

When a drive is replaced, the parameter settings can be retained by transferring the
memory unit from the defective drive to the new. However, non-volatile data stored
using the NVRAM... keywords is not stored on the memory unit by default. Before
removal, use the NVRAMSAVE keyword to store the data on the memory unit.
WARNING! Do not remove or insert a memory unit when the drive is powered.
