The FlashBackup cache partition may have run out of space

In that case, the cache partition may not be large enough for the backup requirements.

If the cache partition is full, messages such as the following appear in the system log:

    WARNING: sn_alloccache: cache /dev/vx/rdsk/flash1dg/f full - all
    snaps using this cache are now unusable
    WARNING: sn_failsnap: snapshot id 5 failed error 28

Specify a larger cache partition, or designate additional cache partitions in the Backup Selections list.
