Adding New Volumes
118 NetBackup Media Manager System Administrator’s Guide for Windows
For example, if a volume in a standalone drive is full or unusable because of errors,
NetBackup requests that Media Manager eject the volume. NetBackup then searches
for another unused volume. If another appropriate volume is not defined, NetBackup
exits with an error.
Labeling a volume and adding it prevents this problem, because Media Manager
displays a mount request for that volume rather than returning an error to
NetBackup.
NetBackup Catalog Backup Volumes
◆
Prior to using volumes for NetBackup catalog backups, you must add them. You can
also use the NetBackup
bplabel
command to label the volume.
See “Adding Volumes Using the Actions Menu” on page 119.
Notes on Labeling NetBackup Volumes
Labeling volumes is controlled by the application. Refer to the NetBackup system
administrator’s guide for Windows servers, the NetBackup system administrator’s guide
for UNIX, or the Storage Migrator system administrator’s guide for more information.
NetBackup controls the labeling of its volumes and in most cases performs this operation
automatically.
◆
If a volume in a robotic library has not been labeled, NetBackup labels it with the
media ID assigned by Media Manager the first time that it uses the volumes for a
backup.
This action is done unless those volumes were last used for NetBackup catalog
backups (you do not want to label these volumes unless they are no longer being used
for catalog backups), or the volumes contain data from a recognized non-NetBackup
application (the NetBackup configuration option,
ALLOW_MEDIA_OVERWRITE
can be
set to allow the volume to be overwritten).
◆
If you prefer to assign specific media IDs to NetBackup volumes, label them using the
NetBackup
bplabel
command and add them using the manual update procedure.
◆
Media Manager uses a default prefix of the letter A, when assigning media IDs to
volumes without barcodes (for example, A00001). To change this default, use the
MEDIA_ID_PREFIX
configuration option.
◆
If the robotic library supports barcodes, by default NetBackup generates media IDs
for new volumes based on the last six characters of the barcode. To change this
default, you can specify and select specific characters using Media ID generation rules
(see “Media ID Generation Tab (Advanced Options)” on page 183).
