Issue Description

After VIS identifies the EVA4100, mapping this LUN to HP host, but HP host cannot identify this LUN. 

Alarm Information

Null

Handling Process

When VIS maps LUN to HP host, set HOST LUN ID as 0. Then HP-UX can identify LUN.

Root Cause

When HP host does not have the LUN which HOST LUN ID is 0, it cannot identify other LUN.

Suggestions

In HP-UX 11.31, if HP host does not have the LUN which HOST LUN ID is 0, it cannot find other LUNs. When VIS maps LUN to host, set HOST LUN ID as 0, then HP-UX can identify LUN. Attention to this when Huawei VIS take place HP array.
