  • 1.  SSD Disk is showing as NON-SSD in Drive type of Esxi

    Posted Apr 25, 2018 07:45 AM

    Hi All Experts,

    I am new to Vmware VSAN exposure and have started to deploy my first VSAN environment.

    I have 3 physical ESXI hosts. (Each host contains 5 Disks i.e One disk dedicated for ESXI OS, three Disk dedicated for capacity disk for VSAN and one disk is dedicated for SSD.

    The problem which i am facing is that my SSD disk is showing as Non-SSD in Drive Type column of ADD Storage options. I am currently using SSD disk of size 256 GB. below is the screenshot for the reference.

    Kindly suggests why it is showing as non SSD in drive type of Add Storage while the disk is SSD.

    Waiting for the response.

    Thanks.

    Muhammad Amir

    Hello Muhammad,

    Don't use the Thick Client for managing or configuring vSAN - multiple features are not exposed and you will run into issues with this, use the Web Client.

    If the disks are not being seen as SSD, you can mark them as Flash devices easily via this method:

    Mark Storage Devices as Flash

    Thanks for the prompt response and help,

    One more thing, if i keep this device (SSD Disk) marked as Non-SSD, then will it make any impact on my VSAN configuration for SSD device addition step.

    Hello Muhammad,

    If it is not detected as SSD and you don't mark it as SSD, it won't be available for selection as cache-tier device when creating the Disk-Group.

    Let us know if this resolves your issue.

    Thanks for the help,

    Issue has been resolved now, i have set the disk type as SSD via ESXCLI command thru SSH the host.

    Without Vcenter, web client cannot mark the drive type as FLASH Disk. This option only comes in Vcenter.

    Thanks for the prompt response and help.

     In what version of ESXi?

    Older method was just:

    esxcli vsan storage tag add -d <device name> -t capacityFlash

    In ESXi 7.x/8.x can use:

    esxcli storage hpp device set -d naa.5001538e4102a7a2 -M true
