Scannning SR HBA: VDI is not avaiable Starting VM: An emulator required to run this VM failed to start

[Krzysztof Halik]

Hello,

I have problems with HBA storage. I can only run VMs once after clean installing or importing from XVA from still working older host machine.

After shutting down the VM machine or rebooting I get the message: VDI is not avaiable OR An emulator required to run this VM failed to start. When I try to rescan SR HBA: VDI is not avaiable.

The only solution is to delete volumen on MSA 2060, create again, attach in XenCenter and format. I have tried to create small LUNs ~100GB, 50GB and still the same. First start is ok, working with out any problems, but after restart VM I get error.

I have two servers HP ProLiant Gen10 in pool connected via FC to HP MSA 2060.

Citrix Hypervisior and XenCenter is updated.

I have similar configuration with HP ProLiant Gen9 with HP MSA 2040 on Citrix Hypervisor 8.2 and it's working fine for 5 years.

 

Please help me with that, I have no idea what to do...

What do you see in the SMlog and kern.log from the same host during the time of the problem ?
