Re: [Veritas-bu] Master server can't see media servers
2007-07-06 02:59:38
Yeah, I know having 50+ media servers is risky....but there
really is no other way to properly do it.
I'm beginning to think it isn't netbackup. My
/usr/openv directory is mounted via a direct connect fibre on a Sun 9990
raid. I'm running veritas file system (vxfs) 5.0. I'm also doing
Veritas Volume Replicator (VVR) to another Sun 9990 raid at a DRS site.
Both sites are connected via a large, private pipe...so bandwidth between the
two sites isn't an issue. But I'm seeing this in my /var/adm/messages
file:
vxio V-5-0-0 disconnecting rlink
rlk_<hostname>_bkprvg due to exessive retries.
Also...when some stuff hangs, and I go into /usr/openv (or
any directory under that) my terminal hangs. I can ssh back into the
box, and I'm okay until I navigate into /usr/openv. I've done a full
fsck of the vxfs file system, it wasn't clean the first time...but has come back
clean since.
So I may be having vxfs issues. :-/
Yippie....

Yeap.. it's odd.. :) well.. as far as I know, it's too risky if
you have that much of media server. Because they alway communicate each
other, and when even one media server couldn't talk, the process will be hung.
Are you already check this:
- on /usr/openv/netbackup/bp.conf, did
all the media server registered there, with the "SERVER = media_server_name"
(without quotes) ?
yes for all of the media server
too?
check on: /usr/openv/netbackup/bin/bpps
-a for the hung processes. try to kill the hung process with ./kill -9
<Hunged PID process> Then you'll know which media server had the
problems.

several months. No recent patch updates or changes (that I'm aware
of). The master server lost "netbackup communication" with the media
servers upon restarting the netbackup daemons.
- did the master server name and ip
address listed on /etc/hosts at all the media server?
yes. I can ping and ssh to all media servers and vice
versa
- on /usr/openv/netbackup/bp.conf,

yes
- check on the media server:
"./usr/openv/volmgr/bin/vmglob get_gdbhost"
It gives me the
master server's hostname
It's odd, huh?

Check it, and give us the result..

Roughly 55 media

After I rebooted the
netbackup daemons, I had the following issue:
Master server can ping and
ssh to all media servers, but Master server cannot communicate to media
servers via netbackup. vmoprcmd command hangs. Any jobs for
media servers that start up come back with "Media server is not
active". Netbackup is running on master server and all media
servers. Tried rebooting the master server with same outcome.
There is no firewall between the master server and any media
servers.
Something obviously changed
before I restarted the Netbackup daemons....anyone have any
ideas?
