Hello
I'm trying to install Oracle Grid Infrastructure 12c Release 1 on Windows Server 2012 R2 in a hyper-v lab (my intention is a full rac install - eventually). I've created my ASM storage using the ISCSI target role (4 disks 20GB each, all dynamically expanding), and they are all visible from both nodes. I can ping all IPs from all relevent servers. I'm at prerequisite tasks, and there is one thing that I'm being to asked to check. Error message is as follows:
"Device Checks for ASM - This is a prerequisite check to verify that the specified devices meet the requirements for ASM. Error:
-
PRVG-10521 : Failed to resolve ASM disk label "ORCLDISKDATA0" to device path on node "ORAN01DV" - Cause: Failed to resolve ASM disk label to any device on specified node. - Action: Ensure that the specified ASM label is correctly stamped on a shared device on the node specified and that the labeled devices are accessible to current user. To verify the label to disk mapping use tools ''Asmtoolg'' on Windows operating system platforms and ''oracleasm'' on the Linux operating system platform.

I have opened Asmtoolg, and everything seems to be ok in there (all disks are stamped and are visible etc). I recognise that this is a complex area, so I understand that it's going to be difficult to difficult to diagnose. I was really surprised not to find any hits anywhere on the internet for the error code PRVG-10521 though. Does anyone have any ideas of things I could try?
Thanks in advance
