Replacing a library
When a library fails, or when the library robotics card must be changed, the replacement will have
a different serial number from the original. To assign it the same pools, mapping, etc. as the original:
NOTE:
While the virtual tapes are in the firesafe, scheduled backups for those tapes will not occur.
1. Make a note of all pool configuration information for pools associated with the library to be
replaced.
2. Delete all pools associated with the library (see Deleting a Copy Pool ).
NOTE:
Deleting the pools automatically moves all virtual cartridges from within the pool to the
firesafe.
3. Unmanage the physical library to be replaced (see Managing and Unmanaging a Destination
Library ).
4. Replace the library or robotics card.
5. Manage the new physical library (see Managing and Unmanaging a Destination Library ).
6. Manually recreate the storage pools associated with the new library using the information written
down at the beginning of this procedure.
The virtual tapes that were moved into the firesafe will automatically return to their previous
locations.
Deduplication Issues
Solution Possible causes Symptom
Consider using cartridges that are
smaller than the sum of your daily
backup jobs so the cartridges dedu-
plicate sooner.
The VLS does not free up storage
on a cartridge until:
• At least two full backups of the
same policy exist on different
cartridges
• The delta-differencer has pro-
cessed all of the backup sets on
the cartridge
• The cartridge is physically full
The VLS is not deduplicating the
backup jobs.
