vCenter - vSAN SSD is not valid

Hi,

I am trying to create a disk group within my cluster disk management. When I open the wizard to create my disk group, you can see the SSD and HDD as you would expect. When I have selected the two drives and clicked on 'OK' I get the error 'Specified SSD is not valid'. I have done the following process with two other servers with the exact same set up and haven't had this issue with them. Could someone please advice on some troubleshooting I could carry out to get this working?

The server is a HP Proliant Microserver Gen8 with a 1TB HDD and a 30GB SSD (We have 3 of these to make up our vSAN lab).

Thanks in advance.

Jon

Jon,

Make sure that the SSD cards are supported. http://www.vmware.com/resources/compatibility/search.php

Hi JD,

The SSD's are supported as they have worked for 2 of the 3 servers.

Cheers,

Jon

Jon,

Did you try to reboot the server ? If possible try detaching the disk and attaching again.

Hi JD,

Rebooting the server is one of the first things to be carried out. We have changed the slots for the SSD and HDD but this has had no effect. We are currently in the process of updating the firmware on the server to see if this makes any difference. However we are slowly running out of ideas.

Is this brand new drives or have they been used before? I had issues using drives that contained raid och partitiondata. Clearing the disks solved that issue.

Hi Jake_Sallee,

Unfortunately I haven't been successful in fixing this issue. I managed to get the vSAN working which was brilliant but I found after a short period of time the SSD would then show the error 'Permanent disk failure'. A quick fix/get around I found for this is to delete the disk group made in the vSAN and then remake it. This would then show no errors and work temporarily but apart from this I haven't had much luck finding a proper solution. The biggest frustration of this is this is all brand new equipment.

Also please note the original issue was fixed by deleting partitions on the disk (windows disk management was used to do this). I have made a new thread for the new error i have got...if you are experiencing this or can help with what i explained in this reply please follow this link -> vCenter - vSAN SSD 'Permanent Disk Failure'
