IBM Power architecture plus multipath means
it is best when @schabrolles has a look...

@pspatola101

could you try without multipath: :

EXCLUDE_COMPONENTS=( "${EXCLUDE_COMPONENTS[@]}" "/dev/mapper/mpathar" "/dev/mapper/mpathas" "/dev/mapper/mpathat")

@pspatola101,

Any news from your side? Did you find the time to test without multipath:

pspatola101 commented at 2018-05-07 20:11:

I apologize for the long delay. I had a family health emergency that required me to take time off from work.
I made the update to the local.conf as you suggested and it worked. I checked the disktodo.conf file and they are marked as done.
[root@ssstfs03 layout]# cat disktodo.conf |grep mpathar
done /dev/mapper/mpathar multipath
done /dev/mapper/mpathar1 part

I checked the disklayout.conf file and they are commented out.
[root@ssstfs03 layout]# cat disklayout.conf |grep mpathar
#multipath /dev/mapper/mpathar 10737418240 /dev/sdba,/dev/sddx
#part /dev/mapper/mpathar 10737369088 24576 GPFS none /dev/mapper/mpathar1

I really appreciate the help with this. I was hoping for an easier solution as I could have numerous gpfs disks on here and more would be added.

pspatola101 commented at 2018-05-07 20:59:

I tried one more thing. I saw someone had written a bash script to do the exclusion. I edited the file like so.
EXCLUDE_COMPONENTS=("${EXCLUDE_COMPONENTS[@]}" "$(/usr/lpp/mmfs/bin/mmlsnsd -m |grep mapper |awk '{print $3}' |sort -u)")

When I run the mkrescue -v it looks as if it will work...
[root@ssstfs03 rear]# rear -v mkrescue

I think we can close this one as it is now solved and continue the discussion about excluding GPFS in #1767
