Important:
A WWN pool can include only WWNNs or WWPNs in the ranges from
20:00:00:00:00:00:00:00 to 20:FF:FF:FF:FF:FF:FF:FF or from
50:00:00:00:00:00:00:00 to 5F:FF:FF:FF:FF:FF:FF:FF. All other WWN ranges are
reserved.
To ensure the uniqueness of the Cisco UCS WWNNs and WWPNs in the SAN fabric, we recommend that you use the following WWN prefix for all blocks in a pool: 20:00:00:25:B5:XX:XX:XX
| Command or Action | Purpose |
---|
Step 1 | UCS-A#
scope org
org-name
|
Enters organization mode for the specified organization. To enter
the root organization mode, type
/
as the
org-name
|
Step 2 | UCS-A /org #
create wwn-pool
wwn-pool-name {node-wwn-assignment |
port-wwn-assignment}
|
Creates a WWN pool with the specified name and purpose, and enters
organization WWN pool mode. The purpose of the WWN pool can be one of the
following:
|
Step 3 | UCS-A /org/wwn-pool #
set descr
description
| (Optional)
Provides a description for the WWN pool.
Note
|
If your description includes spaces, special characters, or
punctuation, you must begin and end your description with quotation marks. The
quotation marks will not appear in the description field of any
show
command output.
|
|
Step 4 | UCS-A /org/wwn-pool #
create block
first-wwn
last-wwn
| (Optional)
Creates a block (range) of WWNs, and enters organization WWN pool
block mode. You must specify the first and last WWN in the block using the form
nn
:
nn
:
nn
:
nn
:
nn
:
nn
:
nn
:
nn
, with the WWNs separated by a space.
Note
|
A WWN pool can contain more than one WWN block. To create
multiple WWN blocks, you must enter multiple
create block
commands from organization WWN
pool mode.
|
|
Step 5 | UCS-A /org/wwn-pool #
create initiator
wwn
wwn
| (Optional)
Creates a single initiator, and enters organization WWN pool
initiator mode. You must specify the initiator using the form
nn
:
nn
:
nn
:
nn
:
nn
:
nn
:
nn
:
nn
.
Note
|
A WWN pool can contain more than one initiator. To create
multiple initiators, you must enter multiple
create initiator
commands from organization
WWN pool mode.
|
|
Step 6 | UCS-A /org/wwn-pool/block
commit-buffer
|
Commits the transaction to the system configuration.
|
The following example creates a WWN pool named sanpool, provides a
description for the pool, specifies a block of WWNs and an initiator to be
used for the pool, and commits the transaction:
UCS-A# scope org /
UCS-A /org # create wwn-pool sanpool node-wwn-assignment
UCS-A /org/wwn-pool* # set descr "This is my WWNN pool"
UCS-A /org/wwn-pool* # create block 23:00:00:05:AD:1E:00:01 23:00:00:05:AD:1E:01:00
UCS-A /org/wwn-pool/block* # exit
UCS-A /org/wwn-pool* # create initiator 23:00:00:05:AD:1E:02:00
UCS-A /org/wwn-pool/initiator* # commit-buffer
UCS-A /org/wwn-pool/initiator #
Include the WWPN pool in a vHBA template.
