I'm not sure it's so uncommon, but yes.  (and your line looks suspiciously like 
mine did)   I've had other situations where it would have been nice to do 
maintenance on a single storage pool.  Maybe this is a "scale" issue when you 
get too large and should maybe have multiple file systems instead?  Single name 
space is nice for users though.
Plus I was curious what others had done in similar situations.

I guess I could do what IBM does and just write the stupid script, name it 
"ts-something" and put a happy wrapper up front with a mm-something name. ;)   

Just FYI:  'suspend' does NOT stop I/O.  Only stops new block creation,so 
'stop' was  what I did.

Subject: Re: [gpfsug-discuss] Disabling individual Storage Pools by     
themselves?

mmlsdisk fs | grep pool | awk '{print $1} | tr '\n' ';'| xargs mmchdisk
suspend
# seems pretty simple to me

Then I guess you also have to modify your policy rules which relate to
that pool.

You're asking for a convenience wrapper script for a super-uncommon
situation?
