HP StorageWorks EVA Storage System

System Parameters
When connecting an EVA storage system as an external storage system, set the system parameters
of the EVA storage system according to
not in Table 49 (page
appropriately for the connecting configuration.

Identifying Logical Volumes (Using Characteristic2)
When the connected external storage system is an EVA storage system, LUNs appear as
Characteristic1 in the XP External Storage windows.
If you search for the logical volumes specifying the WWN indicating EVA Port A in the configuration,
as shown in Figure 44 (page
each of HostGroup- 1 and HostGroup-2. In this case, two different logical volumes that have the
same name, such as LUN 1 and LUN 2, are found as the logical volumes that can be connected
from EVA Port A, but you cannot tell which LUN 1 and LUN 2 belong to HostGroup- 1 or
HostGroup-2 only by Characteristic1.
In the configuration in
Characteristic2 in the XP External Storage windows. The first 32 characters of Characteristic2
indicate the World Wide LUN Name that can be found on the EVA storage system side. You can
identify the logical volume of the EVA storage system by this World Wide LUN Name.

Behavior of the Alternate Path
When an EVA storage system is connected, the behavior of the alternate path differs depending
on the microcode version of the EVA storage system.
If the subsystem system type is EVA3000/5000, the behavior of the alternate path differs between
the EVA storage system of the microcode version 4.000 or later and the EVA storage systems of
the earlier microcode versions.
To replace the microcode of the EVA storage system, check whether the behavior of the alternate
path changes as a result of changing the microcode version. If the behavior of the alternate path
changes, perform the Delete Volume operation of XP External Storage to release the setting of
mapping the EVA storage system volume before you actually replace the microcode.
