Examples

Utilising Pool from the Cluster Object

    >>> from arcapix.fs.gpfs import Cluster
>>>
>>> # Load the cluster
... mycluster = Cluster()
>>>
>>> for stgpool in mycluster.filesystems['mmfs1'].storagepools.values():
...     print stgpool.name
...
system
sas1
sata1
sata2

Utilising Pools directly

>>> from arcapix.fs.gpfs import Pools
>>>
>>> # print a list of names of pools in filesystem 'mmfs1'
... print Pools(deviceName='mmfs1').keys()
['system', 'sas1', 'sata1', 'sata2']
