Re: [Veritas-bu] Storage Unit Strangeness

2007-04-24 Thread Green, Richard R
 We had this same problem where there were more drives used than was
stated in the storage_unit parameters for backups. We have NetBackup 5.1
MP4 on a Sun box with Solaris 10. We have two storage_units. One for
backups on newer tape drives and another storage_unit for old technology
drives to use for restores of older backups.  


After opening a case with Symantec it was determined that we needed to
do the following;

Create a line in /usr/openv/netbackup/db/config/behavior/ called
MAX_DRIVES_THIS_MASTER 12. 12 being the total number o tape drives that
will be used for backups. You will need to determine this number for
your Master. We do this so there is a least one drive available for
restores.

You will then need to stop and restart NetBackup.  

>From the case;
The calculation of active jobs and concurrent jobs is based on:
Definitions.
Active jobs is the sum of mpxgrps (multiplex groups) and a multiplex
group is equivalent to a tape drive.

Concurrent jobs is derived as a minimum of either the available drives
in the robot or the maximum concurrent jobs for all storage units in a
robot.

For this problem:   max concurrent jobs is 32 x 12 = 384, mpx per
drive is set to 32 and 12 drives in the storage unit.
To solve or try to solve the problem comes down to utilizing the
parameter: mdtm MAX DRIVES THIS MASTER.

Bpsched algorithm will check for a hard limit, mdtm and stop allocating
drives at that point.
Any drives that are not allocated due to the hard limit , remain
available for restore work

Hope this helps.

ACS/LS will use whatever it wants.

 

Are all 6 really active?   Is there another application using those
drives somewhere?  ACS/LS may have just left those in the drives...eh,
its been a long time since I rock and rolled with acs

 

What's with the fragment size and the mpx value?

 

:-)
