definition. You can also use Storage Provisioning Manager to streamline this process. See “Storage
Provisioning Manager” (page 60) for more information.
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 check boxes 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 check box if you
want all volumes to implement redundancy, or
• Check the redundancy check box next to a specific volume to implement redundancy for that
volume.
Volume & 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).
The Volume & Path Selection table allows you to enter the storage volume attributes for this storage
pool entry. If you selected the SAN Catalog Storage Entry or SAN Pre-populated Catalog Storage
Entry storage type on the Manage Storage Pool screen, the values in this table are filter criteria for
the candidates that are displayed when you press Show Candidates.
For a SAN Storage Entry, 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
any logical server sharing this storage pool entry.
For all storage types:
1. For a SAN Storage Entry:
a. Click the Add Volume button on the right side of the screen to add a row to the Volume
& Path Selection table.
b. Optional: Check the Redundancy check box next to a specific volume to implement
redundancy for that volume.
c. Select a value from the Boot drop-down menu. Select Yes if the volume is a boot volume.
Select No if the volume is a data volume.
d. Enter the Size in GB for the storage volume.
e. Select a RAID Level for the storage volume.
f. Obtain from the Storage Administrator the storage port WWNs and LUN identifiers
corresponding to the server WWN for each storage volume.
g. Enter the storage port WWN for each server WWN.
h. Enter the LUN identifier for each server WWN.
i. Optional: In the Manage Server WWNs, change the Server WWN by typing in the text
box. This is useful if the SAN is prezoned.
j. Press Save.
k. On the Manage Storage Pool screen, monitor the Status column for the storage pool entry.
