Description Nate Straz 2009-06-08 17:48:26 EDT
Description of problem:

The lssyscfg command issued to the HMC by fence_lpar to get the status of the LPAR can take longer than SHELL_TIMEOUT, 3 seconds.  This results in fencing failures which could be avoided if fence_lpar waited longer for the HMC to respond to the command.

A quick test on squad1hmc showed lssyscfg took up to 7 seconds to complete.

Version-Release number of selected component (if applicable):

How reproducible:
~40% of the time, probably dependent on the HMC

Steps to Reproduce:
1. fence_lpar -o status <lpar dep opts>
Actual results:
Jun  8 15:52:32 basic-p1 fenced[1850]: fencing node "kent-p1"
Jun  8 15:52:38 basic-p1 fenced[1850]: agent "fence_lpar" reports: Connection timed out

Expected results:
fencing should succeed.
