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.
