HP XP P9500 Storage - Manual (Page 48)

•
When a pair is created, the processor blade allocated to the primary volume's LDEV is also
allocated to the secondary volume's LDEV. When a pair is deleted, the processor blade that
was originally allocated to the secondary volume's LDEV is allocated to it again. If the original
processor blade was removed, another processor blade is allocated.
•
When you delete a pair, the status of the volumes changes to SMPL, which no longer displays
in Remote Web Console. However, before becoming SMPL, it first changes to SMPL(PD).
To distinguish between SMPL and SMPL(PD) volumes, run the RAID Manager pairdisplay and
Inqraid commands. The pairdisplay command shows status but cannot distinguish between
SMPL and SMPL(PD); and the Inqraid shows whether a volume is being used by Business
Copy.
◦ If the result of the pairdisplay command is SMPL, and the result of the Inqraid command
is the primary or secondary volume, then Business Copy is still using the pair and status
is SMPL(PD).
◦ If the result of the pairdisplay command is SMPL, and the result of the Inqraid command
is not the primary or secondary volume, Business Copy is no longer using the volumes.
Therefore, status is confirmed as SMPL.
•
After deleting a pair, wait 10 seconds—until volume status changes from SMPL(PD) to
SMPL—before performing tasks such as a pair operation or event waiting. If you do not wait
10 seconds, the operation might end abnormally.
