Hi Aaron
An alternative method for you is:
from arcapix.fs.gpfs import Nsds
>>> from arcapix.fs.gpfs import Nsds
>>> nsd = Nsds()
>>> for n in nsd.values():
... print n.device, n.id
...
/gpfsblock/mmfs1-md1 md3200_001_L000
/gpfsblock/mmfs1-md2 md3200_001_L001
/gpfsblock/mmfs1-data1 md3200_001_L002
/gpfsblock/mmfs1-data2 md3200_001_L003
/gpfsblock/mmfs1-data3 md3200_001_L004
/gpfsblock/mmfs2-md1 md3200_002_L000

Obviously you can filter a specific device by the usual Pythonic string
comparators.

Subject: [gpfsug-discuss] translating /dev device into nsd name
Date: Sat, Dec 17, 2016 6:24 AM
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
