Business Copy XP (BC) for the XP10000/XP12000
Combining BC with other data management operations
BC supports concurrent operations with the following data management functions:
•
LU Size Expansion (LUSE). LUSE volumes can be assigned to BC pairs if the P-VOL and S-VOL have the
same LU type and number of LDEVs (same size). If you must perform LUSE operations on an existing BC
P-VOL or S-VOL, delete the pair first to return the volume to SMPL status.
•
CVS. CVS volumes can be assigned to BC pairs if the S-VOL has the same capacity as the P-VOL. If you
must perform CVS operations on an existing BC P-VOL or S-VOL, delete the pair first to return the
volume to SMPL status.
•
LUN Security. LUN Security operations do not affect BC operations. Volumes under secure ports and/or
assigned to World Wide Name (WWN) groups and/or LUN groups can also be assigned to BC
pairs. Volumes assigned to BC pairs can also be assigned to secure ports, WWN groups, and/or LUN
groups for LUN Security.
NOTE:
BC S-VOLs cannot be accessed by any host except when the pair is split.
•
Cache LUN. Cache LUN volumes can be assigned to BC pairs. Cache LUN operations can be
performed on BC P-VOLs and S-VOLs.
CAUTION:
See ”
” on page 24 for important information on performing quick
restore operations on Cache LUN volumes.
•
Continuous Access XP Journal. Continuous Access XP Journal volumes can be assigned to BC pairs,
and BC volumes can be assigned to Continuous Access XP Journal pairs.
•
Continuous Access XP. Continuous Access XP volumes can be assigned to BC pairs, and BC volumes
can be assigned to Continuous Access XP pairs. See ”
Combining BC and Continuous Access XP
” on page 42 for important information on BC and Continuous Access XP shared volume
configurations.
•
Auto LUN. BC can be assigned to Auto LUN migration volumes. However, if the BC P-VOL is already
paired with three S-VOLs, delete the BC pairs before migrating the volumes. Also, to assign BC volumes
to destination migration volumes or reserve BC volumes for Auto LUN, delete the BC volumes or
unreserve the BC volumes before using them with Auto LUN. If you assign a BC P-VOL that is already
paired with three S-VOLs to Auto LUN migration volumes, or assign BC volumes to Auto LUN volumes
other than migration volumes, the command will be rejected.
If you split the BC pair assigned to Auto LUN migration volumes, migration of those volumes will be
canceled.
NOTE:
You cannot use Auto LUN migration, destination, and reserved volumes for BC pair
operations (the command will be rejected). To use Auto LUN volumes for BC pair operations, use
Auto LUN to release the volumes.
