CLI network timeout on one of the 12 sync commands.

Question

I invoke 12 CLI commands from HPUX 11.31 to synchronize 12 clones within a cloneset. About 1 out of 30 times I get a network timeout on one of the 12 commands. Anybody know why?

A network error occurred while trying to connect: '172.20.50.4'.
Message : Error occurred because of time out

And it happened on ERP_PRD_C_MP85

Loooking at the events on the Service Processors, there are no errors. Ultimately I went into Navisphere and just had the clone synchronize. I probably could have also used the CLI command above to do it as well. The question is

1) Is there a limit to how many commands can be submitted in a row? Should I put a sleep between the commands to slow the script down.

2) Is this really a network error. This usually occurs at 5:00 am when there is almost no network traffic.

3) Any other thoughts as to why I am getting this issue.

they tend to take some time for me, especially if the array is busy. If you don't need consistency can you put them in a for loop ?

JoeCX700 · Answer

So do you get this error or do your commands just run slow?   How many commands at a crack do you submit?   Is 12 commands an unusually large number to submit?

kelleg · Answer

What version of Flare are you running on the array and what is the version of CLI?

Try these two commands - time the response:

naviseccli -h xxx.xxx.xxx.xxx getagent

naviseccli -h xxx.xxx.xxx.xxx -np getagent

If there is a big difference in the time to respond, you problem should review the following:

i never send multiple streams at the same time, i loop through my list of commands, sending one command at a time.
