ViPR SRM Physical host troubleshooting
I have configured several physical hosts in our ViPR SRM system using the hostconfig-srm.pst script. Some hosts show all components and end to end physical connectivity, others are missing data. My question is for those physical hosts that are not showing end to end connectivity or missing components, what do I check for on the physical host side?

I've realized I didn't put version information on there. We are running
It seems that when a physical host isn't reporting all components, it's relating to Storage Connectivity>Path Details.

Hi graterb,
Often the SNIA libraries are either missing or not in a location where ViPR SRM knows to search for them. Also, you may run the LunMappingDetection.ps1 script in debug mode to help with troubleshooting discovery issues such as no HBA's, etc. To do this you would need to open the script in Notepad (or other editing tool that does not add any formatting or non-ASCII characters), navigate to the following line:
$supportOption = "disabled" #enabled
change the "disabled" to "enabled", save the time and then run the script:
powershell.exe -noprofile -file LunMappingDetection.ps1 > LunMapping-debug.log
This will run the LunMappingDetection script and output the information to the debug file for review. Remember to change the file back from "enabled" to "disabled" after the output to the debug log file is successful. Please contact us if there are other questions.
Regards,
Wanda

Thank you Wanda,
Just want to clarify one point, the example I listed above does show HBA's in ViPR, just not the SAN Disks. Other physical hosts show up correctly and I just want to know what to look for. If this is still correct, then I will request the script run on those servers.

Hi graterb,
I would go ahead and run that LunMappingDetection script in debug mode as it will show any issues that the host discovery is having which is useful in the event that you do need to open a Service Request to address the problem.
