I have just installed the ESXi 5.5 on our Dell PER710 server. It has a H700 controller with eight ssd drives in a RAID 10 array.
The ESXi claims that the datastore is "non-ssd" based. Because I am not exactly sure what are the implications of that, I wanted to fix it using the article below.
I went to the "Summary > Storage > Unmount" in the vSphere console before proceeding any further.
Then I added the "enable ssd" rule as per step five.
Unfortunately, when I reboot the server after adding the rule, everything stays the same.
When I try to "unclaim the device" as per step six, I get the following error:
"Unable to perform unclaim. Error message was : Unable to unclaim all requested paths. Some paths were busy or were the last path to an in use device. See VMkernel logs for more information."
And needless to say, I am still getting "Is SSD: false"
I have tried to put the server to the maintenance mode but that did not help either.
