The other day, I would configure an SMI-S connection from SCVMM 2012 R2 to the customer's HP P2000 G3 MSA SAN. I could run through the "Add Storage Devices Wizard" and added the SAN without any problem but it could not find neither vDisk's or any LUN's. I verified the following:
• SMI-S was enabled in the SAN
• The Run As account had SMI-S access to the SAN
The solution: To connect using Telnet to the SAN and run the command "reset SMIS-configuration" for both controllers. Next, the wizard could find vDisk's and LUN's in the SAN.
