[config-reference] Cleanup ibm storwize
The Storwize driver includes a hand-written table with configuration options that duplicated the autogenerated one. Remove the hand-written table. Also fix missing "." in list. Change-Id: Id3955407ab63b7416181f46660932d0ff9a3a617 Related-Bug: #1662922

.. [1]
|
||||
The authentication requires either a password (``san_password``) or
|
||||
SSH private key (``san_private_key``). One must be specified. If both
|
||||
are specified, the driver uses only the SSH private key.
|
||||
|
||||
.. [2]
|
||||
The driver creates thin-provisioned volumes by default. The
|
||||
``storwize_svc_vol_rsize`` flag defines the initial physical
|
||||
allocation percentage for thin-provisioned volumes, or if set to
|
||||
``-1``, the driver creates full allocated volumes. More details about
|
||||
the available options are available in the Storwize family and SVC
|
||||
documentation.
|
||||
|
||||
.. [3]
|
||||
Defines whether thin-provisioned volumes can be auto expanded by the
|
||||
storage system, a value of ``True`` means that auto expansion is
|
||||
enabled, a value of ``False`` disables auto expansion. Details about
|
||||
this option can be found in the ``–autoexpand`` flag of the Storwize
|
||||
family and SVC command line interface ``mkvdisk`` command.
|
||||
|
||||
.. [4]
|
||||
Defines whether Real-time Compression is used for the volumes created
|
||||
with OpenStack. Details on Real-time Compression can be found in the
|
||||
Storwize family and SVC documentation. The Storwize or SVC system
|
||||
must have compression enabled for this feature to work.
|
||||
|
||||
.. [5]
|
||||
Defines whether Easy Tier is used for the volumes created with
|
||||
OpenStack. Details on EasyTier can be found in the Storwize family
|
||||
and SVC documentation. The Storwize or SVC system must have Easy Tier
|
||||
enabled for this feature to work.
|
||||
|
||||
.. [6]
|
||||
The driver wait timeout threshold when creating an OpenStack
|
||||
snapshot. This is actually the maximum amount of time that the driver
|
||||
waits for the Storwize family or SVC system to prepare a new
|
||||
FlashCopy mapping. The driver accepts a maximum wait time of 600
|
||||
seconds (10 minutes).
|
||||
|
||||
.. [7]
|
||||
This option allows the driver to map a vdisk to more than one host at
|
||||
a time. This scenario occurs during migration of a virtual machine
|
||||
with an attached volume; the volume is simultaneously mapped to both
|
||||
the source and destination compute hosts. If your deployment does not
|
||||
require attaching vdisks to multiple hosts, setting this flag to
|
||||
``False`` will provide added safety.
|
||||
|
||||
.. [8]
|
||||
Defines whether or not the fast formatting of thick-provisioned
|
||||
volumes is disabled at creation. The default value is ``False`` and a
|
||||
value of ``True`` means that fast format is disabled. Details about
|
||||
this option can be found in the ``–nofmtdisk`` flag of the Storwize
|
||||
family and SVC command-line interface :command:`mkvdisk` command.
|
||||
|
||||
.. [9]
|
||||
This option allows that the sum of all volume's provisioned capacity to
|
||||
be larger than the pool’s total capacity. The default value is 20.0,
|
||||
which means that the provisioned capacity can be 20 times of the total
|
||||
physical capacity.
