another drive sled. If one drive fails, DriveCopy
may be used to copy the data off the remaining
drive on the sled to another drive on another sled.
Once completed, the sled containing the failed
drive may be replaced.
CAUTION CAUTION
Make sure the destination backup drive
sled does not contain any important data
because it will be completely overwritten

drives for backup. However, since several
configurations may be present on a Diamond
Storage Array, you must be confident you are
accessing and overwriting the appropriate drives
and volumes.
RAID Level 1 and RAID Level 10
should not need to be backed up by copying drives
since these settings already provide mirrored
copies of drives. However, you may copy a drive
to another drive within a RAID Level 1 or RAID
Level 10 system, but the destination drive cannot
contain data you want to save.
You might want to keep an entire group (LUN)
free of data to use as spare drives within the array
system.
RAID Level 0 and RAID Level 5 systems
may be used to coordinate the
DriveCopy
generation of a backup of an entire RAID Level 0
or RAID Level 5 LUN.
