Once the snapshot is created, it is verified and .log files are truncated. For this, the checkpoint
is fetched and log file names are traversed one by one. This may take a longer due to a large
number of .log files for a mailbox database/storage group. If a virtual copy creation is taking
too long, check the virtual copy creation with the -nc switch. This will skip log verification and
log truncation. Then, verify this snapshot using the validate command. After it is validated, to
truncate logs, create a snapshot using the -truncate and -nc switches. Finally , try a regular
virtual copy creation. If the virtual copy creation with -nc is also taking a longer time, send an
RMReport to HP Customer Support.
