Adding a WWN Block to a WWNN Pool
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

Deleting a WWN Block from a WWNN Pool
If you delete an address block from a pool, Cisco UCS Manager does not reallocate any addresses in that
block that have been assigned to vNICs or vHBAs. All assigned addresses from a deleted block remain with
the vNIC or vHBA to which they are assigned until one of the following occurs:
• The associated service profiles are deleted.
• The vNIC or vHBA to which the address is assigned is deleted.
• The vNIC or vHBA is assigned to a different pool.
