Thanks Bryan,
It happens directly after reboot.. The thing is: - I have deactivated all polices - Stop our media server - And then restarted netbackup on the master. So there are absolutely no action going on (no backup, no user backup, no restore, no staging) only internal netbackup work . At once when netbackup on the master gets active, it starts bpdbm process after bpdbm process. It consume 100% of both my CPU`s and write/read heavily to the /usr/openv/netbackup/db filesystem. When I have no action at all after a clean start, we have about 42 bpdbm processes and nearly as many bprd processes I cant figure this one out, and support points to disk config or something else that sounds good in there ears Thanks for all help, Hampus Lind Rikspolisstyrelsen National Police Board Tel dir: +46 (0)8 - 401 99 43 Tel mob: +46 (0)70 - 217 92 66 E-mail: [EMAIL PROTECTED] -----Ursprungligt meddelande----- Från: Bahnmiller, Bryan [mailto:[EMAIL PROTECTED] Skickat: den 14 februari 2007 20:04 Till: Hampus Lind Ämne: RE: [Veritas-bu] Serious master issue... Hampus, How quickly does this behaviour start happening after a recycle/reboot? I worked with an N4000 master running 11i. We did have 8 cpus and 8 GB RAM. We were running over 15,000 backup jobs daily though. Our catalog was over 400GB. (Catalog was on EMC DMX disk.) Running good old 3.4 we would have to reboot the system almost every week. If you can cleanly re-cycle NetBackup - shut it down, kill all NBU processes, and then restart it, that should be almost as good. Here we are running NBU 5.1mp4 on a Win2K3 master - 2 cpus, 4 GB RAM. (I inherited the system - not my choice.) We run about 5000 jobs per day, we have a 280 GB catalog on EMC Clariion. The system will stay stable for 2 weeks pretty easily. 4 weeks starts pushing things. So we usually reboot our Windows master and media servers every 2 weeks. It seems like you will have cumulative problems with NetBackup that can build up over time. It is way more pronounced on busy systems. We have another NetBackup system that has 1 Master and 1 Media server. It runs about 40 jobs per day max. I hardly ever have to reboot those servers.

Importance: High All, Now I have been transferred to USA support God bless America! They have told me that they havent seen such a big installation in over a year . Strange, I have about 200 clients and backup a couple a TB per day.. I was under the impression that this was kinda small installation..?? However, they have told me that this is perfectly normal behaviour with netbackup. That it produces heavy disk IO and eat all CPU power. And I was really stupid and told them that I also had an case with HP earlier on this disk IO problem, so now Symantec support are pointing all there fingers at HP and our disk setup. Our DB is about 60-65 GB and resides on a StorageTek Flexline 380 disk array (SAN). We run a RAID 5 on 146GB FC drives.. I dont really see the bottleneck there, but I will create a RAID 5 on 73GB 15K FC drives just to shut netbackup support up We run a two CPU HP rp2470 with HP-UX 11.11 as a master server. Shouldnt this be enough for this installation? Ooh well If support cant help me, what should I do?? I am desperate!!!

Prioritet: Hög Hi, We have a serious issue here with our master server. The problem occurred a couple of weeks ago, or at least I found out about it then.. I was looking at IO`s and scsi queue depth on my master (hp-ux 11.11) when a say that we had 4000-6000 SCSI commands in que, and a disk utilisation of 100% for the /usr/openv/netbackup/db disk. I have patched hpux to the latest patch bundle and we run NBU 5.1 MP4. HP support sad that bpdbm was leaking memory. Veritas support still investigating.. But we have about 30 bpdbm and bprd processes active on our master which eats both my CPU`s and produces tons of IO against our db disk. I actived verbose = 5 on the master, and after 15 minutes the bpdbm log had reached the file size limit on our filsystem, 2 GB Any one had similar problems?
