Figure 6-5 Create logical server SAN port definition
Volume and path definition
After creating and presenting the volumes (LUNs), the storage administrator provides the server
administrator with the information required to complete the logical server storage definition.
This information includes:
• Storage WWN, uniquely identifying the port used to communicate with the SAN
• LUN, uniquely identifying the created volume within the SAN
Using these two pieces of information, the path to the LUN is unique within the FC environment.
Redundancy
Multiple ports help performance and improve reliability through redundancy and failover
capability.
For redundancy checkboxes to become enabled, you must define two ports (one primary and
one secondary) in the Port Selection table.
• Check the Use Redundancy for all Storage Volumes for this Logical Server checkbox
if you want all volumes to implement redundancy, or
• Check the redundancy checkbox next to a specific volume to implement redundancy for
that volume.
Volume and path selection
A volume is a fixed disk drive on a disk array in a storage area network (SAN) that is not
necessarily mapped to a controller port. When a storage volume is mapped to a controller port,
it becomes addressable in the SAN as a logical unit number (LUN).
Entering storage port WWN and LUN values in the Volume & Path Selection table is optional
on this screen, but you must enter those values before you can activate the logical server. If you
do not enter the values on this screen, you can modify the storage entry for this logical server
later.
The Volume & Path Selection table allows you to enter the storage volume attributes for this
logical server.
1. Click the Add Volume button to on the right side of the screen to add a row to the Volume
& Path Selection
table.
2. Select a value from the Boot Volume drop-down menu. Select Yes if the volume is a boot
volume. Select No if the volume is a data volume.
3. Enter the size in GB for the storage volume. (Size is typically 10-30 GB.)
4. Select a RAID Level for the storage volume. The default is None.
5. Assign the port number to be the Primary boot path (and Secondary boot path, if you selected
Redundancy for the storage volume).
6. Obtain storage port WWNs and LUN identifiers corresponding to the server WWN for each
storage volume. (If these values are not readily available, you can save this storage entry
and use the Modify
→Logical Server... menu selection to add storage values later. The
