Volumes

Creating and Modifying Volumes

Creating volumes is done with the create method:

>>> v = system.volumes.create(pool=pool, name='my_vol')

Note

When a size is not explicitly stated, a default of 1 GiB is used. You can also provide the size explicitly:

>>> from capacity import GiB
>>> vol = system.volumes.create(pool=pool, size=1*GiB)

It is also possible to create multiple volumes with a single line, by calling create_many():

>>> vols = system.volumes.create_many(pool=pool, name='vol', count=5)
>>> len(vols)
5
>>> for vol in vols:
...     print(vol.get_name())
vol_1
vol_2
vol_3
vol_4
vol_5

We can now access various attributes of the volume:

>>> print(v.get_name())
my_vol
>>> v.get_size()
1*GB

Volume Serials

InfiniSDK exposes the volume WWN serial number through a custom type, enabling you to parse it easier:

>>> serial = v.get_serial()
>>> print(serial) 
742b0...3ef
>>> serial.ieee_company_id
7613199
>>> unused = serial.system_id
...
>>> serial.volume_id
1007

Moving Between Pools

Use Volume.move_pool() to move a volume between pools:

>>> new_pool = system.pools.create()
>>> v.move_pool(new_pool)

Deleting Volumes

Deleting a volume is done with Volume.delete():

>>> v.delete()

Example: Deleting All Volumes with Specific Name Prefix

>>> for volume in system.volumes:
...     if volume.get_name(from_cache=True).startswith('prefix'):
...         volume.delete()
