Have you checked to see if you are forcing your nic's and switches. If
they are set to auto negotiate then that could b e your issue. Also
upgrade it to MP5 there is network issues with mp3

I have a SUN L20 tape library runing as a media server
for veritas netbackup 5.1 on SUN solaris 9. the systems
runs however SOMETIMES performance is terrible.
for example, a recent backup from a local disk to tape
got 60KB/s in throughput.
enviroment : solaris 9, netbackup 5.1 MP3, drive cleaned regularly.
on media server /etc/system:
set shmsys:shminfo_shmmax=4294967295
set shmsys:shminfo_shmmin=1
set shmsys:shminfo_shmseg=10
set shmsys:shminfo_shmmni=512
set semsys:seminfo_semmns=2048
set semsys:seminfo_semmni=2048
set semsys:seminfo_semmsl=250
set msgsys:msginfo_msgmni=1024
set msgsys:msginfo_msgtql=1024
set semsys:seminfo_semopm=128
on media server /usr/openv/netbackup/
NET_BUFFER_SZ = 262144 in /usr/openv/netbackup
SIZE_DATA_BUFFERS = 262144 in /usr/openv/netbackup/db/config
NUMBER_DATA_BUFFERS = 32;
I even have an entry per veritis recommedation
SIZE_DATA_BUFFERS_DISK = 1048576
NUMBER_DATA_BUFFERS_DISK= 16
can anybody offer some clues what is wrong here?
Thanks.
Jason
