Formatting The Dmlu In The Event Of A Drive Failure - Hitachi AMS 2000 User Manual

Formatting the DMLU in the Event of a Drive Failure

When the DMLU is in a RAID group or DP pool with RAID5 or RAID6 and a
drive failure occurs on the RAID group or DP pool with no redundancy, the
data in the DMLU will be incomplete and unusable.
At that time, for the firmware version of 08C3/F and later, the DMLU will
automatically become unformatted, so make sure to format the DMLU.
For less than 08C3/F, even though the DMLU will not automatically become
unformatted, make sure to format the DMLU.
It is possible to format a DMLU without having to release the DMLU.
