Manually mount vol A00005 from pool NetBackup on file /tmp/tapefile. This is helpful if you need to dump data to a tape outside of the NBU application. As NBU mounts the tape it will not attempt to use the tape or drive again until the tape is unmounted.
# tpreq -m A00005 -p NetBackup /tmp/tapefile
Once the tape is mounted then data can be copied to /tmp/tapefile via tar, dd etc.
Unmount the tape which was mounted above
# tpunmount -f /tmp/tapefile
To run a dd test on the cart V05673
# dd if=/dev/rmt/51cbn of=/dev/null bs=256k
Change a volume pool for a volume. Note that it is only possible to change the volume pool for an unassigned tape cartridge i.e. a cartridge listed in the NBU catalog as being empty.
# vmchange -p volume_pool_id -m media_id
Add a scratch pool to NBU
# vmpool -add scratch “Scratch Pool” ANYHOST -1 -2
List the scratch pool in use
# vmpool -listscratch
To unfreeze a tape
# bpmedia -unfreeze -m <barcode>
To add a tape, which is in slot 1 in the library (rc1 1) to the volume database on a master server but the robotic control host is on nbumedia1
# vmadd -m A00001 -mt dlt -h nbumaster -rt tld -rn 0 -rh nbumedia1 -rc1 1
When adding a cleaning cartridge to NBU to enable NBU to carry out the cleaning you must specify the density type as
<density>_clean i.e. HCART_CLEAN / HCART2_CLEAN
To delete a tape from the volume database
# vmdelete -h nbumaster -m media_id
To expire a volume immediately
# vmchange -exp expiration_date -m media_id
# vmchange -exp 0 -m SE2005
To deassign a volume so you can move it between volumes pools. Once that is done then use vmchange to move, if needed.
# vmquery -deassignbyid mediaid pool_id stat
# vmquery -deassignbyid SE2005 3 0
The stat value refers to the type of backups the cart was used for : 0 is for regular backups, 1 is for catalog backups
If you want to get rid of the images that are on a tape, expiring the tape itself will also expire all images on the tape. The following will expire the tape and corresponding images immediately
# bpexpdate -ev mediaid -d 0
Add the use_seed option to automatically generate media ids
# vmupdate -rt tld -rn 0 -rh nbumedia1 -h nbumaster -use_seed
To see a list of media expiration dates:
# bpmedialist -summary
To erase a tape – be careful as this will not check if valid images are present on the tape before erasing it.
# bplabel -erase -m <barcode> -d <density> -p <volume_pool> -host <media server to perform the erasure>
The bplabel command will mount the tape onto a tape drive visible to the specified media server and erase the tape header, hence you will see the erase job within the NBU job DB.
To add a barcode rule
# vmrule -add <barcode_tag> <media_type> <volume pool> <max mounts> <description
To add a rule so that all barcodes with a first character of “T”, a density of HCART2 and no maximum mounts are added to the scratch pool, use :
# vmrule -add T hcart2 Scratch 0 "Data Tapes"
To delete a barcode rule
# vmrule -delete <barcode_tag>
# vmrule -delete T
