Maintenance and Service Guide
Installing a new RAIDset or mirrorset member
To install a new RAIDset or mirrorset member, insert a new disk drive that
satisfies the replacement policy of the reduced storageset into the PTL location of
the failed disk drive.
Note: HSG60 and HSG80 array controllers automatically initialize a new disk drive
and place this disk drive into the spareset if the AUTOSPARE switch is enabled. (By
default, array controllers are set to NOAUTOSPARE.) As soon as the disk drive
becomes a member of the spareset, array controllers automatically use the disk drive
to restore the reduced RAIDset or mirrorset. If initialization of the new disk drive fails,
the disk drive is placed into the failedset.
Tip: Depending on the system load and the number of drives installed, you may need
to wait 1 to 5 minutes between the removal and installation of a replacement disk in
order for the replacement procedure to complete properly.
Moving a reduced RAIDset across subsystems
If you move a RAIDset to another subsystem and back to the original subsystem,
and the RAIDset is reduced somehow during transition, create a RAIDset with
members of the normal RAIDset as well as a newly initialized disk. Doing this
allows you to mount the RAIDset back into its original controller. The following
steps outline how to correctly move a RAIDset in this manner.
