Re: Still seeing Fenced out on a few SSA pdisks, any thoughts?

Talked to one of our guys who did a lot with SSA stuff. Usually for us it is a
wiring issue but sometimes other things can cause a reservation problem.
He says may be a lock problem. Here is a snippet from our script that does ssa
certifies for us...

if /usr/sbin/ssa_certify -l $pdisk > $tmp 2>&1

then

stat=$?

else

stat=$?

if grep 'ssa_certify:[ ]*Reservation[ ]*conflict[ ]*accessing ' $tmp >/dev/null

then

#

# Getting the above error output and a rc=1 after 0 seconds.

# IBM PMR 77923,500 Tala said these lock files sometimes cause

# problems. I'll remove only when we see the error.

integer rmd=0

cd /etc/objrepos && for lock in diag_lock config_lock

do

[ -a $lock ] && rm $lock && ((rmd=rmd+1))

done

if [ $rmd -gt 0 ]

then

/usr/sbin/ssa_certify -l $pdisk > $tmp 2>&1

stat=$?

fi

fi

Subject: Still seeing Fenced out on a few SSA pdisks, any thoughts?



AIX'ers,



I'm still seeing fenced out errors when I try to certify 4 disks only in a
drawer.

"Pdisk41 is reserved or fenced out"



This is aix 4.3.3.11 (application constraint)

This is standalone system; this is not a hacmp environment.

This SSA drawer does use SSA 2 cards,

The SSA loops look correct,

If I umount the filesystems on these drives then the certify works, there are no
fenced out errors.

Sending a snap to IBM, they see no problems on this system.



Any thoughts and make it a great day!
