HP Insight Virtualization Manager with Logical Server Management 6.1 User Guide

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.
2. Select a value from the Fabric drop-down menu.
3. Optional: Select a value from the Speed drop-down menu, or accept the default Auto.
4. Optional: Enter a value in the Server WWN text box. By default, the current server WWN
is entered.
5. Repeat steps 1 through 4 for each port for this logical server.
6. 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.

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.
