the microprogram offline, pool information or Snapshot XP pair information in shared memory is lost.
Therefore, you must create pools and pairs again after replacing the microprogram.
Combining Snapshot XP with other software products
You can create Snapshot XP pairs by sharing volumes with other products, such as Business Copy XP
or Continuous Access XP. In addition, you can create Snapshot XP pairs using volumes to which LUN
Security XP Extension or RAID Manager XP have assigned attributes. Table 8 shows whether or not
Snapshot XP pairs can share volumes with other software products.

1 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
whose MU number is 1 and whose P-VOL is also used as a Snapshot XP P-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 RAID Manager XP to set extents, Zero Read Capacity, or Invisible attribute. For more
information, see the HP StorageWorks RAID Manager XP user guide .
• You can check if the volume has the Read Only attribute, Protect attribute, S-VOL Disable, VMA,
extents, Zero 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 .
When Snapshot XP shares volumes with the software products shown in Table 8 , some operations are
restricted according to the pair statuses.
Combining Snapshot XP with Business Copy XP
When the Snapshot XP P-VOL and Business Copy XP pair's volume are shared, the relationship between
the Business Copy XP pair status and Snapshot XP operations is shown in Table 9 and Table 10 .
