after upgrading my ProLiant DL180 G6 server from ESXi 5.0 to ESXi 5.1 the following storage problems appeared:
Warning message on configuration - storage - smart array P410 controller
and unable to open vmdk files on logical volumes:
the firmware upgrade and replacement of VIB drivers has been resolved according thread
http://communities.vmware.com/message/2228698#2228698
But the following error, when starting a VM (WinXP), which was set up and ran well before Upgrading to ESXi 5.1, still appears every time:
vmWare knowledge base: http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2036572
Powering on a virtual machine after upgrading to ESXi 5.1 fails with the error:
File [VMFS volume] VM-name/VM-name.vmdk was not found (2036572)
Does anybody know more about this issue? the proposed workaround, converting all vmdk files to flat, is quite poor, has just blown up the size of my vmdk by factor 7..8, but not resolved the problem.
Appreciate other experiences with that problem, thank you for any help in advance.
