Greetings everyone;
I have a server that runs software called Hobbit which monitors systems for
various events such as full disk drives, ping failures, excessive processor
load, etc. One of the things we want to monitor via hour Hobbit server is
the status of NetWorker backups.
I have two NetWorker servers. Let's call one X and the other server Y.
Server X is a Sun T2000 with Solaris 10 and NetWorker 7.4.1. Server Y is a
Dell 2950 with Red Hat Linux AS 4.5 and NetWorker 7.4.4. The Hobbit server
is also running Red Hat Linux and NetWorker client 7.4.4.
On the Hobbit server, when I do something like
mminfo -v -s X -c client1 -ot
The response takes around 6-7 minutes to appear.
If I do something like
mminfo -v -s Y -c client2 -ot
I get a near instantenous response.
If I log onto server X and do the same
mminfo -v -s X -c client1 -ot
Command, I get a near instantaneous response.
NetWorker server X has two NICs. One NIC has various tagged VLAN addresses
associated with it. They all work fine for backups. The second NIC is the
one over which the mminfo query is being done from the Hobbit server. This
second NIC isn't in heavy use at all. Its 1GB and its autonegotiating
properly with our switch.
If I log onto one of the clients that gets backed up to Server X via one of
its tagged VLAN addresses, the same mminfo command gets a very fast
response.
I have been working with one of our network management type people on this
problem and he sees nothing wrong on either end. Server X responds to mminfo
commands quickly on a variety of other servers, except when the commands
come from our Hobbit server. The mminfo commands to NetWorker server Y also
result in fast responses. I can also back up the Hobbit server to Server X
reasonably fast.
If anyone has any ideas why mminfo commands take so long to process from our
Hobbit server on only NetWorker server X, but NetWorker server X provides
fast mminfo reports to other servers, please let me know.
