Problem

Maximum partially full volumes has been reached

 

Solution

In an effort to have media filled with backups before requesting more media, NetBackup volume pools can be set to only have a certain number of volumes in an 'active' state.
When that number of active (non-full) volumes has been reached, backup jobs will remain in a queued state while other jobs are writing their backups.
 
Check theMaximum number of partially full media is more than 0,
 
One may view the limit set using
/usr/openv/volmgr/bin/vmpool-listall
===================================================================
poolnumber:  0
poolname:    None
description:  the None pool
maxpartially full:    0
================================================================================
poolnumber:  1
poolname:    NetBackup
description:  the NetBackup pool
maxpartially full:    1
================================================================================
poolnumber:  2
poolname:    DataStore
description:  the DataStore pool
maxpartially full:    0
================================================================================
poolnumber:  3
poolname:    Catalog Backup
description:  NetBackup Catalog Backup pool
maxpartially full:    0
================================================================================
In this example, only 1 volume are allowed for volume pool "Netbackup" to be written atone time, even though there are available resources (tapes and drives) that could utilized.
 

Solution:

Change the Maximum number of partially full media to 0:
 
 
This limiter can be changed to 0 using the commands below:
 
Windows
<install_path>\veritas\volmgr\bin\vmpool-update -pn NetBackup -mpf 0
UNIX/Linux:
/usr/openv/volmgr/bin/vmpool-update -pn NetBackup -mpf 0
 
vmpool -update -pn pool_name -mpf mpf_max

Changes an existing volume pool. Optionally limits the number of partially full media to be used in this pool by using -mpf. The default value is zero (0), which indicates that the number of partially full media is unlimited.
