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 Pairresync operations for important information on performing quick restore operations on
Cache LUN volumes.
