I was experiencing a disk health issue on an ESXi host in a vSAN setup.
Possible solution :-
Replace the disk and recreate the disk group on esxi (during the maintenance time) to address the issue.
Go to vSAN > Disc management > Cluster > configure.
View Objects (displays all disc information on the cluster)
The commands listed below are extremely useful for troubleshooting and gathering information.
> esxcli vsan cluster get
> esxcli vsan storage list | grep -i cmmds
> esxcli vsan storage list | grep -i dedup
> esxcli vsan storage list | grep -i enc
> vdq -Hi
> df -h
> esxcli vsan debug object health summary get
> esxcli vsan health cluster list
> esxcli vsan health cluster get -t "Operation health"
> esxcli vsan health cluster get -t "Network latency check"
> esxcli vsan cluster unicastagent list
> cmmds-tool find -t HOSTNAME
> cd /var/run/log
> less vobd.log
> less vmkernel.log
> less vmkernel.log| grep -i 0x28
> zcat vmkernel.* | grep -i ox28
> zcat vmkernel.* | grep -i 0x28
> zcat vmkernel.*.gz | grep -i 0x28
> vmkernel.*.gz | grep -i failed
> zcat /var/log/boot.gz | grep -i firmware
> zcat /var/log/boot.gz | grep -i fw
