hello in my case i was loosing connectivity to datastore and after some seconds restored..(vmware 6) ibm x 3550 m2, 4 ssd raid 5.
i was looking and reading around more than a month..
after a powe loss and a ups ran out of batteries.. the system didn't came back .. so i start really examine the system and i found my little button battery was bad.. actually the battery itseld was ok 3 volts but the system show an error ( a led on motherbaord)
after i change it according to ibm instructions..( power off etc.. )
the system volume works fine since..
its been 1 week without any errors.
