HP Insight Virtualization Manager with Logical Server Management 6.1 User Guide

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 & Path Selection
A volume is a fixed disk drive on a disk array in a storage area network (SAN). 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 entry or storage pool entry.
On the storage pool entry screen, if you checked Use Catalog Storag e, the values in this table
are filter criteria for the candidates that are displayed when you press Show Candidates.
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 containing the operating system. Select No if the volume is a data volume.
If you specify only one storage volume, it must be a boot volume. If you specify more than
one storage volume, only one can be a boot volume.
The default is Yes for the first volume added, and No for subsequent volumes added. Exactly
one volume within the entire logical server must show a boot volume value of Yes.
3. Enter the size in GB for the storage volume.
4. Select a RAID Level for the storage volume.
5. If you selected Redundancy for the storage volume: Assign the port number for the Primary
and Secondary boot path.
6. If you did not check Use Catalog Storage on the storage pool entry screen, or if you are
entering information on the storage entry screen (where Use Catalog Storage is not
available).
a. Obtain from the Storage Administrator the storage port WWNs and LUN identifiers
corresponding to the server WWN for each storage volume.
b. Enter the storage port WWN for each server WWN.
c. Enter the LUN identifier for each server WWN.
7. If you checked Use Catalog Storage on the storage pool entry screen:
a. Check the Masked checkbox if you want the volume to be presented to the server WWN
during boot. If this checkbox is unchecked, the volume is a data disk that hidden from
the server WWN during boot.
You may want to uncheck this checkbox if the volume is a data disk that you do not
want seen at boot time. For example, if you are provisioning Linux on the logical server,
you must uncheck (to unmask) the data disk.
b. Press Show Candidates. The available storage port WWNs are displayed in the
Candidates drop-down menu.
