IMPORTANT: You must check the Ready check box next to each server WWN before the storage
pool entry can be shared by logical servers. The Ready check box 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 23 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 Server storage screen, or the Modify Logical Server 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. Matrix OE communicates to verify that the defined paths
and volumes are available.
