Terry,
Anything in /var/log/messages?
lsluns is just a perl script, so I took a peek... I have lsluns from
s390tools-1.11.x-1bb17.20110103.s390x so things maybe different in the
older versions.
Since you don't have a lun configured on the 0.0.5401 0x500507680110a31b
path, lsluns should try to configure lun zero for you. Then look up the
new sg device and run 'sg_luns /dev/sgXXX'. If you have a line like this
in lsluns:
70 my @output = `sg_luns /dev/$sg_dev 2>/dev/null`;
I think if you remove the "2>/dev/null", there will be a much better error
message.
It seems like my version of lsluns has all of the right error handling,
but who knows... maybe there is a bug.
