Re: windows 2012r2 cluster failed to bring disk online

sounds like a config or install problem.  Did you setup MPIO correctly?  Sounds like you are saying its not working so that means its most likely a config problem.  check through the configurations and maybe reinstall MPIO and DSM or contact support.

Re: windows 2012r2 cluster failed to bring disk online

Hi ihave migrating Hyper-V cluster from 2012 to 2012r2. Config of HP MPIO DSM are exactly same as on old cluster node, it seems to be some incompatibility with newer OS. I have uninstalled HP DSM and currently i have only MS DSM and it working fine on 2012r2, disk come online without problem. Only month earlier i have read compatibility document that only supported lefthand os is 11 with 2012r2 as initiator and now it change to support also 10.5, but problem with version 11 is that it still not available due to delay, for online upgrade with CMC, so something is wrong with bad testing compatibility with 2012r2 and 10.5 lefthand os.

sounds like you have to contact support then to get this sorted out.

 

I assume you have tried to clear the PR flag on the disks?
