HP XP External Storage Software - Manual (Page 125)

If you search for the logical volumes specifying the WWN indicating the EVA Port A in the configuration
such as Figure 49 on page 125, the logical volumes named LUN 1 and LUN 2 are found for 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 Characteristic 1.
In the configuration such as
Figure 49 on page 125, you can identify the logical volumes referring to
Characteristic 2 in the External Storage windows. The first 32 characters of Characteristic 2 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.

only by Characteristic 1
Note on Behavior of Alternate Path when EVA Storage System is Connected
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 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 External Storage to release the setting of mapping the EVA
storage system volume before you actually replace the microcode.
Please see the EVA storage system manuals for how the behavior of the alternate path changes.
System Parameter Settings for Connecting Sun StorEdge
6120/6320
When you connect a Sun StorEdge 6120/6320 as an external storage system, set the system parameters
of the Sun StorEdge 6120/6320 according to the following table. For the system parameters that are
not in the following table, see the manuals of the Sun StorEdge 6120/6320 and set the parameters
appropriately for the connecting configuration.
