Hi. I'm working on a problem on one of our P570's with 2 vio servers. I'm attempting to backup the vio server with backupios -nosvg -file /path/to/nimserver/nfsmount The write performance is extremely slow. I know there is not usually a quick answer to perf questions, but have any of you seen this before.

The failover p570 frame right next to this one has 2 vio's that backup in about 30min - 1hr, much faster so I don't believe its the NFS server. Is there anything I can look at on the vio that might cause this? So far all configs on the vio's look the same.

Any help is much appreciated.

Thanks!

...found the problem,

netstat -i
Name Mtu Ipkts Ierrs Opkts Oerrs Coll
en1 1500 9564987 0 3573825 14139 0
en1 1500 9564987 0 3573825 14139 0

Very high rate of Oerrs. Took a look at the interface speed:

entstat -d en1 | grep -i media
Media Speed Selected: Auto negotiation
Media Speed Running: 100 Mbps Half Duplex

The interface needed to be forced 1000-FDX

Hi

That's why i always ask for setting the switch's ports used for my AIX LPARs to a fixed speed and do the same at AIX level.
