Interoperability with Other Products and Functions
XP Snapshot can create pairs by sharing volumes with other program products, such as Business Copy or
Continuous Access. In addition, you can create XP Snapshot pairs by using volumes to which attributes
are assigned by HP StorageWorks XP Data Retention Utility or RAID Manager. The following table shows
whether or not XP Snapshot pairs can share volumes with other program products.
Table 4 Volume Sharing with Other Program Products
Volumes of Other Program Products XP Snapshot Pair P-VOL XP Snapshot Pair S-VOL
Business Copy pair P-VOL OK* No
Business Copy pair S-VOL OK* No
Continuous Access pair P-VOL OK No
Continuous Access pair S-VOL OK No
HP StorageWorks XP Continuous Access
Journal Software pair P-VOL
OK No
Continuous Access Journal pair S-VOL OK No
Auto LUN source volume OK No
Auto LUN target volume No No
Read Only volume OK OK
Protect volume OK OK
S-VOL Disable volume OK OK
Zero Read Capacity volume OK OK
Invisible volume OK OK
Note*: A Business Copy pair and an XP Snapshot pair cannot have the same mirror unit (MU) number.
For example, if the MU number of the Business Copy pair is 0, you cannot create an XP Snapshot pair
whose MU number is 0 and whose P-VOL is also used as a Business Copy P-VOL. Also, if the MU number
of the XP Snapshot pair is 1, you cannot create a Business Copy pair whose MU number is 1 and
whose P-VOL is also used as an XP Snapshot P-VOL.
Notes:
• You need Data Retention Utility to set the Read Only attribute, the Protect attribute, or S-VOL
Disable. For details, see the HP StorageWorks XP24000 Data Retention Utility User’s Guide.
• You need RAID Manager to set the Zero Read Capacity attribute or the Invisible attribute. For
details, see theHP StorageWorks XP RAID Manager User’s Guide.
• You can check if the volume has the Read Only attribute, the Protect attribute, S-VOL Disable, the
Zero Read Capacity attribute, or the Invisible attribute by seeing the window of Data Retention
Utility. For details, see the HP StorageWorks XP24000 Data Retention Utility User’s Guide.
When XP Snapshot shares volumes with the program products shown in Table 4 on page 18,
some operations are restricted according to the pair statuses. For detailed information, see
“ Data Retention Utility ” on page 19 through “ HP StorageWorks XP Thin Provisioning Software ” on page 23.
