Re: [Veritas-bu] Storage Unit Strangeness
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. ___ Veritas-bu maillist - Veritas-bu@mailman.eng.auburn.edu http://mailman.eng.auburn.edu/mailman/listinfo/veritas-bu
Re: [Veritas-bu] Storage Unit Strangeness
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? :-) From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Greenberg, Katherine (ISD, IT) Sent: Tuesday, April 24, 2007 9:41 AM To: veritas-bu@mailman.eng.auburn.edu Subject: [Veritas-bu] Storage Unit Strangeness Have a support call open, but find you guys to have seen more than they have sometimes ;) Solaris 9 NBU 5.1 MP4 Media server NBU 5.1 MP6 Master The storage unit for media server (the only one for that media server) is configured to use 3 drives, however the media server has 6 drives in use...
