IMPORTANT: If you configure your Virtual Connect logical server to use a local disk, you cannot
move that logical server. Additionally, after you activate the logical server, you cannot reactivate
it on a different system.
Perform the following steps to define a SAN or RDM storage entry.
1. Enter the “SAN storage entry definition” (page 46)
2. Enter the “Port definition” (page 46)
3. Enter the “Volume and path definition” (page 47)
4. Optional: Verify “Validation status” (page 48)
SAN storage entry definition
1. Optional: Change the name of the storage entry by typing in the name box. Each storage
entry is given a unique default name.
2. Optional: Enter a description for the storage entry. If you enter a description and insert the
entry into the storage pool, it is displayed in the Select Pool Entry drop-down menu on the
Modify Storage Configuration tab and the Create Storage Configuration screen.
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 check box 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 pre-presenting LUNs.
