Hi,
We upgraded our hardware on our master server about a week ago, and we've had
no
end of grief ever since. (note that we upgraded from 3.4 to 4.5 at essentially
the same time)
The errors we are getting are mostly:
Subject: Backup on fred - 134 started
Status = unable to process request because the server resources are busy.
but closely followed by:
Subject: Backup on fred - 24 started
Status = socket write failed.
Subject: Backup on fred - 40 started
Status = network connection broken.
Subject: Backup on fred - 49 started
Status = client did not start.
Subject: Backup on fred - 13 started
Status = file read failed.
Subject: Backup on fred - 228 started
Status = unable to process request.
And we are talking in the hundreds of messages/trys per day
(3500 odd since last wednesday)
And appears to be affecting all clients (sol2.6 and Sol6)
Some backups end up completing after many tries, some simply fall out of their
window and fail.
Our hardware chaged from:
Sun Microsystems 280R, 2 x UltraSparcIII 750MHz, 2GB ram, GB eth
To:
Sun Microsystems 420R, 4 X UltraSPARC-II 450MHz, 4GB ram, GB eth
IBM 6 Drive anaconda robot (LTO) attached by fibre to the same machine
Could there possibly be some setting that are uber important that i missed ?
The things I can think of are (and match the previous server):
bob[/]# head -15 /etc/system
*ident "@(#)system 1.18 97/06/27 SMI" /* SVR4 1.5 */
*
* SYSTEM SPECIFICATION FILE
*
set shmsys:shminfo_shmmax=4294967295
set shmsys:shminfo_shmmin=1
set shmsys:shminfo_shmmni=512
set shmsys:shminfo_shmseg=100
set semsys:seminfo_semmns=500
set semsys:seminfo_semmni=150
set semsys:seminfo_semmap=350
set semsys:seminfo_semmnu=700
set semsys:seminfo_semume=100
set semsys:seminfo_semmsl=100
bob[/]# cat /usr/openv/netbackup/db/config/NUMBER_DATA_BUFFERS
16
bob[/]# cat /usr/openv/netbackup/db/config/SIZE_DATA_BUFFERS
131072
load on the server is not particularly high, plenty of memory and swap free,
ethernet interface not saturated by far
Is there a list of what resources available that NB coulld possibly be
referring to when it claims
"server resources are busy"
As usual, veritas knowledgebase was useless :(
Anyone spotting anything dead obvious here, or know where else i should look ?
TIA
