Hi all,
Found another xCAT bug, this time with the /opt/xcat/sbin/configmic
that is used to bring the MIC cards up.
For some reason on our system when this script runs the values of
$nodename is the short form hostname and $nodename_short is the long
form hostname. Yet if I run hostname and hostname -s I get the
short form in both cases.
However, the wget that works is for the long form hostname.
Anyway, that's not the bug, the bug is that if $nodename_short works
the configmic script then goes on to use $nodename later on in the
script and everything fails.
With the attached patch it makes $nodename be $nodename_short if it
worked to recovery the config file from the MN and suddenly everything
works nicely, both MICs on our statelite nodes are configured and boot
to Linux. They even have working external bridges and IPs!
I've been able to get rid of a heap of our nasty work arounds for
getting them to boot with xCAT 2.8.2 so I'm pretty happy!
All the best,
Chris
