Address pools

To add, edit, or remove an address pool, complete the following steps.

About this task

Attention: Duplication of MAC addresses can cause serious issues with your network. Fibre Channel address duplication can lead to data corruption, if more than one server is attempting to access the same volume at the same time.

The following notes describe information that you must consider when you add, edit, or remove an address pool:

Some applications check the adapter type and vendor using the address. You can select ranges that meet the requirements of the type of adapter that you are using. Each vendor has allocated a special range for IFM which guarantees that these addresses do not conflict with any previous or future burned-in addresses.
For Fibre Channel addresses there are two ranges for each vendor: one for odd-numbered ports and one for even-numbered ports.
Note: For some devices this might not be the appropriate allocation. For example, a Fibre Channel high speed adapter is connected to ports 6 and 8, which are both allocated out of the second range. This device might appear as two different devices rather then a single device.
The worldwide node name (WWNN) is for a Fibre Channel device attached to the port. Not all applications require this value, and some adapters supply this value themselves by creating a number based on a transformation of the worldwide port name (WWPN).
The WWPN is for Fibre Channel devices attached to the port. Invalid addresses result in an error and the line is ignored.

Procedure

Select Address Pools.
Select Ethernet, Fibre Channel, or SAS. The summary view shows information about the address pools. You can also select a line to view detailed information. IFM comes with several predefined read-only parent pools. A parent pool can have multiple child pools but all addresses within them must be unique. Max Server Offset is the maximum width of any server associated with the pool. This is a 0 indexed value. For single-bay servers this value is 0.
Select an action from the following choices:
- Add
  Select this choice to add an address pool. You can select the default Ethernet ranges or create your own. When you create a new pool, the currently selected pool is used as the parent.
- Edit
  Select this choice to edit the address pool.
- Remove
  Select this choice to remove the selected address pool.
