You can use PSA SATP claim rules to tag SSD devices that are not detected automatically.

About this task

Only devices that are consumed by the PSA Native Multipathing (NMP) plugin can be tagged.

If you need more information about the commands listed in this topic, see the Getting Started with vSphere Command-Line Interfaces and vSphere Command-Line Interface Concepts and Examples documentation.

Procedure

  1. Identify the device to be tagged and its SATP.
    esxcli storage nmp device list 

    The command results in the following information.

    naa.6006016015301d00167ce6e2ddb3de11
    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 PSA claim rule to mark the device as SSD.
    • You can add a claim rule by specifying the device name.

      esxcli storage nmp satp rule add -s SATP  --device device_name --option="enable_ssd"
    • You can add a claim rule by specifying the vendor name and the model name.

      esxcli storage nmp satp rule add -s SATP  -V vendor_name -M model_name --option="enable_ssd"
    • You can add a claim rule based on the transport protocol.

      esxcli storage nmp satp rule add -s SATP  --transport transport_protocol --option="enable_ssd"
    • You can add a claim rule based on the driver name.

      esxcli storage nmp satp rule add -s SATP  --driver driver_name --option="enable_ssd"
  4. Reclaim the device.
    esxcli storage core claiming reclaim --device device_name
  5. Verify if devices are tagged as SSD.
    esxcli storage core device list -d device_name

    The command output indicates if a listed device is tagged as SSD.

    Is SSD: true 

What to do next

If the SSD device that you want to tag is shared among multiple hosts, make sure that you tag the device from all the hosts that share the device.
