All,

 

Now I have been transferred to USA support
 God bless America!

 

They have told me that they haven?t 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 don?t 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. Shouldn?t
this be enough for this installation?

 

Ooh well
 

 

If support cant help me, what should I do?? I am desperate!!!

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? 

 

 

Thanks and regards,
