HP UNIX Host Fails to Detect the LUN Mapped by VIS6000 after Taking over HP EVA4100

Publication Date:  2012-07-17 Views:  148 Downloads:  0
Issue Description
After the VIS detects and maps the LUN of the EVA4100 to HP host, HP host cannot detect the mapped LUN.
 
Alarm Information
None
Handling Process
When the VIS maps the LUN to the HP host, set the HOST LUN ID to HOST LUN 0.Then HP-UX can detect the LUN.
Root Cause
When the HP host has no LUN with ID 0, the host fails to detect other LUNs.
When the VIS maps the LUN to the HP host, the HOST LUN ID is not set to zero and the HP host fails to detect the LUN.
 
Suggestions
In hp-ux 11.31, when the HP host has no LUN with ID 0, the host fails to detect other LUNs. When the VIS maps the LUN to the HP host, set the HOST LUN ID to HOST LUN 0.Then HP-UX detects the LUN. You need to configure the HP host when Huawei VIS takes over HP disk arrays.
