esxcli storage nmp device list

 

Run this command to add a PSA claim rule to mark the device as SSD:

# esxcli storage nmp satp rule add --satp=SATP_TYPE --device naa.6006016015301d00167ce6e2ddb3de11 --option "enable_ssd"

For example:

# esxcli storage nmp satp rule add --satp=VMW_SATP_CX --device naa.6006016015301d00167ce6e2ddb3de11 --option "enable_ssd"

esxcli storage nmp satp rule add --satp=VMW_SATP_LOCAL --device naa.600508e0000000000e53078148f38508 --option "enable_ssd"

Run this command to enable local and SSD at the same time:

# esxcli storage nmp satp rule add –-satp=VMW_SATP_LOCAL –-device naa.6006016015301d00167ce6e2ddb3de11 --option "enable_local enable_ssd"

For example:

# esxcli storage nmp satp rule add --satp=VMW_SATP_LOCAL --device naa.6006016015301d00167ce6e2ddb3de11 --option "enable_local enable_ssd"

You must restart the ESXi host for the changes to take effect.

Run this command to check the SSD status:

# esxcli storage core device list -d naa.6006016015301d00167ce6e2ddb3de11 |grep SSD
