Doing this from memory... so TEST it yourself... but this should work...

for x in `symaccess -sid SID list -type storage -dev DEV -output xml  |grep group_name |sed 's/<[^>]\+>//g'`

do

symaccess -sid SID -name $x -type storage remove devs DEV -unmap

done

something like that..

All I can say, disable the device on all the FA's at one shot to stop the host r/w, and remove one by one... I'm not sure whether "Marks" script works... will try later...

when you have multiple MV with the combination of chosen volume and FA port(s), you can unmap a device from a FA port when you remove the device from last storage group,

Sunil_nc:

That's a good point.  We have a bunch of 3-way Clusters and BCVs so that the same Device is masked (and mapped) to multiple different servers and FA Ports in different patterns - I won't be able to "-unmap" the device from the 1st 2 servers, because it will need to be mapped to mask to the 2nd and 3rd servers, etc.  I'll see how that goes.....

Yeah,  I wasn't sure you'd be able to unmap them because I wasn't sure where you had them mapped to..

Archuperi:

I wound up doing something like that after "dynamox" answered.  Thanks.  I wasn't removing all of the devices from the Storage Groups, just some of them.

Furthermore it appears that you can't remove the "last" device (not the highest address, but the actual 1 remaining device).  I saw it in another forum answer.  I'm not doing that, so I'm good.

I meant to say,

If 1 device is added to multiple MV, with combination of 1 PG & multiple SG, then you can unmap the device when you touch last group or MV.
