So just look at your good paths and build a grep -v that matches what you need:
This is what we see. so grep -v "2, 4"
n. active, declustered state,
pdisk total paths array free space remarks

Knew I had a better one around here somewhere:
mmlsrecoverygroup <RG-NAME> -L --pdisk | grep "1, 2"

There is much you can do with 'lsscsi' and "mmlspdisk" and whatnot. Or
something like "mmgetpdisktopology > /tmp/mmgetpdisktopology.out; topsummary
/tmp/mmgetpdisktopology.out > topsummary"
mmlspdisk should all 4 paths with 2 being notenabled. Look for missing paths?
This may be the fastest.
" device =
"//ibmgssio5-hs.ten/dev/sdo(notEnabled),//ibmgssio5-hs.ten/dev/sdfe(notEnabled),//ibmgssio6-hs.ten/dev/sdo,//ibmgssio6-hs.ten/dev/sdfe"
"
If you are using IBM ESS hardware you can make some guesses and then use the
Seagate tools to look and see if each SG device has drives.
"for i in `lsscsi -g -v | grep encl | grep 5147 | awk '{print $7 }'`; do echo
"*** $i ***"; /usr/lpp/mmfs/updates/latest/firmware/enclosure/wbcli $i
ddump_hid | egrep "FLASH" -B8; echo; done"
We've got 5147-106 drive enclosures so I can check each disk...
" i=0; while [ $i -lt 106 ]; do echo "+++ $i +++";
/usr/lpp/mmfs/updates/latest/firmware/enclosure/wbcli /dev/sg131
"getdrivestatus $i" | grep "LED : ON"; sleep 1; let i=i+1; done "
Lots of options. Now that said, many of these are slower than the
gnrhealthcheck for me. Your milage may vary.

Subject: [EXTERNAL] [gpfsug-discuss] ESS and Disk Paths
We have a nearly new ESS5000 (we're still attempting to commission it...)
Anyway, does anyone know a quick way to check if all the paths to the trays are
working?
We've got 5 trays and one of the Servers can only see one of the 5 trays via
one path, and its not causing an alert until we run a full "gnrhealthcheck"
which we only found when attempting to upgrade it. Looking closer in the gui
all the disks in that tray are recording 3 paths not 4 but its not causing any
health alerts.
Don't worry we've got a ticket open and they are attempting to replace the
cable, I'm just attempting to find a nice quick way to detect the problem and
know when its resolved rather than waiting 5 minutes while the gnrhealthcheck
runs.
