3. Optional: Change the Maximum Number of Sharers (maximum number of logical servers
that will be allowed to share this storage entry), then click Update Maximum Sharers.
As logical servers share this storage entry, they are assigned one specific server WWN per
port.
4. Optional: Check the Insert Storage Entry into Pool checkbox if you want to save the
storage entry details that you enter on this screen as a storage pool entry.
After inserting the storage entry into the pool, you can view (but not modify) the entry by
pressing View in the Actions column of the Storage Assignments table on the Create:
Storage Configuration screen. If you create a storage entry and add it to a storage pool, you
can modify the storage pool entry only using the Modify→Logical Server Storage Pools...
menu selection.
If you create a storage entry and do not check Insert Storage Entry into Pool, you can later
modify the storage entry using the Modify button on the Create: Storage Configuration
screen.

Port definition
The Port Selection table allows you to define the ports that can be used to access the volume
selections for this logical server.
Any communication with SAN storage starts with the server’s Fibre Channel ports. Ports are
added in sequential order. For each port, you must select the fabric from a drop-down menu
with which the port will communicate. Each port is created with an automatically generated
server WWN assigned to it. This WWN, like a MAC address for NICs, is used to uniquely identify
this FC port to the SAN. The storage administrator provides access to these ports when
prepresenting LUNs.
1. Click the Add Port button to add a row to the Por t Selection table. You add a maximum
of two ports.
2. Select a value from the Fabric drop-down menu.
3. Select a value from the Speed drop-down menu.
For Fibre Channel ports, select 1Gb, 2Gb, 4Gb, or Auto (FC).
For Fibre Channel over Ethernet (FCoE) ports, select 1Gb, 2Gb, 4Gb, 8Gb (FCoE) or Custom
(FCoE) from the drop-down menu. If you select Custom (FCoE), enter a port speed in the
text box. Custom port speed values can be 0.1 through 10.0 Gb, in increments of 0.1Gb.
4. Repeat steps 1 through 3 for each port for this logical server.
5. To remove the last port added to the table, click the Remove Last Port button. Ports must
be removed in the reverse order in which they were added.
