Grouping RAIDs with other Grouped RAIDs
Just as RAID sets can be grouped, individual groups of RAID sets can be brought together
to form an even larger group.
Deleting Grouped RAIDs
CAUTION:
data on those shares will be lost.
Deleting the RAID set group will delete all member RAID sets, all their volumes and
shares, and all their data. If one RAID set becomes inaccessible for any reason, the entire
RAID set group will also become inaccessible. Depending on the cause, the RAID set group
may or may not be recoverable.
Snapshot Pools are Combined
When two RAID sets are grouped, the size of the resulting snapshot pool is the sum of each
RAID set's formerly separate snapshot pools.
Two RAIDs at a Time Grouping Rule
To group more than two RAID sets, create a RAID group with two RAID sets, then group
each remaining RAID set one at a time.
