Change the hard disk drive type from HDD to SSD in vmware esxi6.5

Environment: host in vmware web client6.5, host IP is 10.1.1.47

Purpose: in order to configure VSAN, you need to change one of the three hard disk types created into a SSD type as a buffer.

Step 1: open the SSH of the host so that xshell can connect, configure-> Security profile-> Edit

Open ESXI Shell and SSH manually

Disable lock mode, configure-> Security profile-> lock mode

Connect using xshell

Enter your password to log in

Step 2: change the hard drive type

Esxcli storage core device list

Find the target hard drive

You can see that Is SSD is marked as False at this time

Create a SATP rule and set the optional parameter to enable_ssd

Esxcli storage nmp satp rule add-satp VMW_SATP_LOCAL-device mpx.vmhba0:C0:T1:L0-option "enable_local enable_ssd"

Note the corresponding disk number

Check out the SATP rule you just created

Esxcli storage nmp satp rule list | grep enable_ssd

Then restate the disk

Esxcli storage core claiming reclaim-d mpx.vmhba0:C0:T1:L0

Verification

Esxcli storage core device list-d mpx.vmhba0:C0:T1:L0

You can see that the modification has been successful.

If you want to restore SSD to HDD, execute

Esxcli storage nmp satp rule remove-satp VMW_SATP_LOCAL-device= "mpx.vmhba0:C0:T1:L0" esxcli storage core claiming reclaim-d mpx.vmhba0:C0:T1:L0 esxcli storage core device list-d mpx.vmhba0:C0:T1:L0

You can see that Is SSD becomes False.
