[gpfsug-discuss] translating /dev device into nsd name

[Aaron Knister]

Hi Everyone,

I'm curious about the most straightforward and fastest way to identify 
what NSD a given /dev device is. The best I can come up with is 
"tspreparedisk -D device_name" which gives me something like:

tspreparedisk:0:0A6535145840E2A6:/dev/dm-134::::::0:

that I can then parse and map the nsd id to the nsd name. I hesitate 
calling ts* commands directly and I admit it's perhaps an irrational 
fear, but I associate the -D flag with "delete" in my head and am afraid 
that some day -D may be just that and *poof* there go my NSD descriptors.

Is there a cleaner way?

-Aaron
