VSphere ESXi How to mark disks as SSD disks

1. Background

When doing a vsan experiment, you need at least one SSD disk as the read/write cache. If there is no SSD disk, we need to mark the normal HDD disk as SSD. Parameters need to be modified.

2. Steps

The first step: Find the ID of the disk that needs to be modified to SSD: Red is the ID of the disk as follows

[Email protected]:~] ESXCLI Storage Core Device List

Mpx.vmhba1:C0:T1:L0

Display name:local VMware Disk (mpx.vmhba1:C0:T1:L0)

Has Settabledisplay Name:false

size:20480

Device type:direct-access

Multipathplugin:nmp

Devfs path:/vmfs/devices/disks/mpx.vmhba1:c0:t1:l0

Vendor:vmware

Model:virtual disk

revision:1.0

SCSI Level:2

Is Pseudo:false

Status:on

Is Rdmcapable:false

Is Local:true

Is Removable:false

ISSSD: false

Second step: Create a SATP rule with the--option parameter set to ENABLE_SSD, as follows:

[Email protected]:~] esxcli storage nmp SATP rule add--SATP vmw_satp_local--device MP

x.vmhba1:c0:t1:l0 --option "Enable_local ENABLE_SSD"

View SATP rule Configuration succeeded

[Email protected]:~] esxcli storage nmp SATP Rule list | grep ENABLE_SSD

Vmw_satp_local mpx.vmhba1:C0:T1:L0

enable_local ENABLE_SSD User step three: Reclaim re- The following:

[[Email protected]:~] ESXCLI Storage core claiming reclaim-d mpx.vmhba1:C0:T1:L0

Fourth Step: Verify the success of the modification, in Ssd:true, indicating that the modification was successful. Re-scan the disk to start the Vsan experiment.
