HP Virtualization Manager with Logical Server Manager 6.2 User Guide

IMPORTANT: You must check the Ready checkbox next to each server WWN before the storage
pool entry can be shared by logical servers. The Ready checkbox is grayed out and checked by
default for a SAN Catalog Storage Entry and a SAN Pre-populated Catalog Storage Entry.
For a SAN Storage Entry and a SAN Catalog Storage Entry, after presentation is complete,
modify the storage pool entry, select a Storage Port WWN from the drop-down menu and press
Save. You cannot activate a logical server until this step is performed.
The number of server WWNs allocated to each port of a storage pool entry is based on the number
of allowed sharers specified by pool entry’s Maximum Number of Sharers field. One server
WWN is allocated per port for each allowed sharer. As logical servers share this pool entry, they
are assigned one specific server WWN per port.
The value in the Available column in the Storage Pools table on the Manage Storage Pools
screen is determined by the number of server WWNs you have checked as Ready, minus the
number of server WWNs that are already assigned (the number of logical servers sharing this
pool entry).
Figure 6-13 Manage storage pool
The number of storage entries that appear as Available in the Storage Pool Entries table on the
Manage Storage Pools screen is determined by the number of server WWNs marked as Ready
minus the number of logical servers that are already sharing the storage entry:
Available = Ready - Sharers
If two or more ports are specified, the port with the lower number of server WWNs marked as
Ready is used to determine the number of available storage entries.
The Owner column shows the name(s) of the logical server(s) that share the storage pool entry.
A storage pool entry has an owner only if it has been associated with a logical server on the
Create Logical Ser ver storage screen, or the Modify Logical Ser ver storage tab.
Validating storage
You can optionally validate your Virtual Connect logical server storage configuration by
performing on-demand checking of Enterprise Virtual Array (EVA) and Modular Smart Array
(MSA) storage. Validation allows you to identify and correct errors by confirming the existence
of each storage WWN and LUN ID pair. It also compares each storage volume attribute by
displaying the user-defined value with the actual value. Insight Dynamics communicates with
the underlying environment to verify that the defined paths and volumes are available.
