AIX AGENT 3.0 RESTORE Slow, Times Out and Fails

Post by JCM »

Case # 05736623

Our restore from VB&R to AIX fails after two hours. Connection and processing continue until it hangs at the 2 hour mark and then nothing.
The commands are at command line and not in the background.
The directory is .22GB
File count 30276

VB&R version 11a
AIX Agent 3.0
AIX OS 7100-05
IBM power 8
The restore hangs and does not continue.
The speed on the restore is 800Kb/s and the backup is 250M/s
loopback (lo0) MTU is at 16896

The error in the log once the process stops executing is:
There was no finalized server sessions during the last 60 minutes.

As seen in the logs, it repeats every hour.

I have changed OS tuneables but nothing seemed to have made a difference.
Made changes to:
tcp_keepidle, tcp_keepintvl, tcp_keepinit

In the logs, Reconnect options: [enabled: timeout 1800000, interval 5000], stay the same.

Network Admin does not see any issues.

Any suggestions of what to check would be appreciated.

in the end it will be checking the logs on the agent and backup server side. As far as I see, support requested some more logs and hopefully they find something then.

TCP timeouts should be irrelevant for such an operations and I would not change too many things at the same time.

What I noticed is, that you still use AIX agent 3.0. I would update to 4.0 first and see whether that solves it.

Best regards,
