Enable Virtual (Edit screen) |
By default, virtual addresses and identifiers are enabled so server profiles will be configured with virtual addresses and identifiers. |
Type |
There can be more than one of each type of pool; multiple autogenerated and custom pools. |
Enabled | If you enable one or more virtual addresses or identifiers, a newly created server profile will be able to use them. When you disable virtual addresses, server profiles can only use physical addresses and identifiers. There must be at least one enabled pool range. |
Start | Starting address in the pool. When you enable virtual addresses or identifiers, the predefined range is selected. The predefined range is large and randomly generated to prevent conflicts between profiles created in different realms. IEEE Standard WWNs are used for the WWN pool, prepending
Examples:
|

Count | Total number of addresses in the pool |
Allocated | Number of addresses in use |
Available | Number of available addresses remaining |
Remove | Click X to remove the pool of addresses and make them unavailable. The X becomes visible when Count equals Remaining. |
