HP StorageWorks Application Recovery Manager Administrator's Guide (T4395-96004, February 2008)

Backup
Overview
Chapter 338
Limitations
• When a cloning process of a source volume is in progress, another
snapshot (any type) of that source volume cannot be created.
• Only one type of target volume per source volume can exist on an
EVA disk array at the same time. For example, the creation of a
snapclone may fail if a snapshot or vsnap for the same source volume
exists on the array. Such replicas should be deleted first using the
Application Recovery Manager command omnidbvss.
HP StorageWorks Disk Array XP Specifics
• For backups in resync mode, the number is limited to a maximum of 3
replicas (S-VOLs) per source volume (P-VOL). If you use the same
P-VOL in more than one backup specification, note that the Number
of replicas rotated should not be more than 3 in all backup
specifications together.
• You can change the XP hardware provider mode between different
backup sessions using the same backup specification, but this is not
recommended when you use replica rotation, because restore of such
a backup can fail. See “HP StorageWorks Disk Array XP
Considerations” on page 55 for details.
