You can tag an automatically detected SSD device as a non-SSD device.


  1. Identify the device that you want to untag.
    esxcli storage nmp device list 

    You might see the output similar to the following:

    Device Display Name: DGC Fibre Channel Disk (naa.6006016015301d00167ce6e2ddb3de11)
    Storage Array Type: VMW_SATP_CX
    Storage Array Type Device Config: {navireg ipfilter}
    Path Selection Policy: VMW_PSP_MRU
    Path Selection Policy Device Config: Current Path=vmhba4:C0:T0:L25
    Working Paths: vmhba4:C0:T0:L25
  2. Note down the SATP associated with the device.
  3. Add a claim rule with the option disable_ssd.
    esxcli storage nmp satp rule add -s SATP --device device_name --option disable_ssd

    For example,

    esxcli storage nmp satp rule add -s VMW_SATP_CX --device naa.6006016042fa19010a12d9b16d6ade11 --option disable_ssd
  4. Reclaim the device.
    esxcli storage core claiming reclaim --device naa.6006016042fa19010a12d9b16d6ade11 
  5. Check the device status by running the following command.
    esxcli storage core device list -d device_name

    The command output indicates whether the disk is untagged.

    Is SSD: false
