2.3

Checking the WWNs

*2: When multiple ESX servers share ETERNUS DX LUNs, any ETERNUS DX CA port that connects a shared
LUN to an ESX server must be assigned to the same reset group, whether multi-paths are used for the
ESX servers or not.
Example: When multiple ESX servers share ETERNUS DX LUNs, CM#0 CA#0 Port#1 and CM#1 CA#0 Port#1
must be assigned to the same reset group, even for single-path configurations.

2.2.2

Setting the Subsystem Parameters (for HP-UX only)

Disable the [Load Balance] parameter in "Set Subsystem Parameters" screen. This prevents sense responses
that require access retries from being issued when the ETERNUS DX is overloaded.
For HP-UX server, improper logs may be recorded unless sense response is restricted. Therefore, "Load Bal-
ance" should be disabled. (Sense response should be restricted.)
Note that changing the "Load Balance" setting has no affect on non-HP-UX servers.
2.3 Checking the WWNs
Use ETERNUS Web GUI to check the WWN of each ETERNUS DX. They are required for connecting the ETERNUS
DX to the server.
