When using the latest version of HP XP Device Manager, I have found that the HostLunID is missing in the LUN Masking report.
Can you confirm you are using version HDvM 7.1.1 or later? If so, what version of STM are you using? Brian
Here is the output from the Proifiler HPXP Provider info report:
CIMOM Version Device Manager CIMOM version 7.0.1 Provider Version HP P9000 Command View Advanced Edition Supported Spec Versions 1.5.0
See if you can upgrade to 7.1.1.
