make_net_recovery slow

[Bob Carback]

I'm running a make_net_recovery from an rx2620 and archiving onto an rx4640. The process has been running for 4 hours -- says it is making an archive that is 3.7 GB -- " The archive is estimated to reach 3771405 kbytes." so far the archive is 120 MB. During the make_net_recovery there is a lot of ---
NFS server uni-rx4640-03 not responding still trying
NFS server uni-rx4640-03 not responding still trying
NFS server uni-rx4640-03 ok

--- being displayed. A ping between the 2 servers looks good ---

Any idea why so slow and why the NFS messages?

Hi

You can try to re-export the NFS filesystem one more time
exportfs -a

You can check if this would help.

Thanks but that did not make a difference.

Hi,

It looks like the connection between NFS server and client is getting dropped and come up after sometime.

First of all , it is required to ensure you have latest NFS RPC patches installed on both servers.
Check the patch status using
# show-patches -a

Do you see any errors in syslog,dmesg on both servers?

Are these server on the same subnet?
Is there any firewall in between them?

When you see this erro, run these command
at server
# nfsstat -s
# mount -v
# netstat -s
run these command at client using
# rpcinfo -u nfs
# rpcinfo -s mountd
# rpcinfo -p

I see you started giving points to the replies for your questions which is good.
Maybe you can assign points for earlier replies later!!

[Bob Carback]

I am unable to run a command such as 'show-patches'. These are on the same subnet and there is no firewall. I see no messages in syslogd or dmesg. This is a new install -- HP-UX 11iv2 12/2005.
# nfsstat -s --- shows all zeros (0)

# mount -v

Bob,

There are so many aspects one should check at network and nfs(itself) level.

I would advise to go through Dave Olker's NFS white paper. He is well known NFS Guru.
http://www.docs.hp.com/en/1435/NFSPerformanceTuninginHP-UX11.0and11iSystems.pdf

This would help you to check every aspect and find the cause of the issue.

Since the installed OS version is pretty much latest, I would suspect the cause like
incorrect network card speed settings ( half or full duplex) etc.

[Luk Vandenbussche]

Hi,

What is your network setting

lanadmin -x 0?
Is it the same on your switch

Modify the ignite settings with

instl_adm -f

fe

instl_adm â d > /tmp/cfg

add the following entry to /tmp/cfg

_hp_lanadmin_args=â -X 100FDâ

instl_adm â f > /tmp/cfg

[Bob Carback]

the switch port and lan card on the server are both set to 100 FD.
This also happens when I try to scp from one of the servers to another unrelated server. I've even tried it on a couple different NIC cards on my server. I'll call support

[Bob Carback]
