A Business Copy XP and Snapshot XP pair cannot have the same mirror unit (MU) number. For example, if the Business Copy
XP pair’s MU number is 0, you cannot create a Snapshot XP pair whose MU number is 0 and whose P-VOL is also used
as a Business Copy XP P-VOL. Also, if the Snapshot XP pair’s MU number is 1, you cannot create a Business Copy XP pair
whoseMUnumberis1andwhoseP-VOLisalsousedasaSnapshotXPP-VOL.
NOTE:
• You need LUN Security XP Extension to set the Read Only attribute, Protect attribute, S-VOL Disable,
or VMA. For more information, see the
HP StorageWorks LUN Security XP Extension user guide .
• You need R AID Manager XP to set extents, Zero Read Capacity, or Invisible attribute. For more
information, see the
HPStorageWorksRAIDManagerXPuserguide .
• You can check if the volume has the Read Only attribute, Protect att ribute, S-VOL Disable, V MA,
extents, Zer o Read Capacity attribute, or Invisible attribute by accessing the LUN Security XP Extension
pane. For more information, see the
HP StorageWorks LUN Security XP Extension user guide .

restricted according to the pair statuses.
