Identifying disk slot in a diskgroup in vSAN 5.5

[krishnaprasad]

Hi, In vSAN 5.5, it's hard to identify the exact physical drive (in vSAN 5.5) which is part of a vSAN disk group. In ESXi 6.x, the HDD blink option (health status plugin) resolve this.

"esxcli storage core path list" command provides Adapter, Channel, Target and LUN details. For example, if a specific drive shows vmhba0:C0:T3:L0, does it mean the physical disk is on the 3rd HDD slot ?

Identifying the physical slot of a specific HDD which is part of a specific diskgroup in vsandatastore is something what I look for in vSAN 5.5. Kindly let me know if this is possible ?

Thanks,

Krishnaprasad

Can you check if this will working for you ?

esxcli storage core device physical get -d <naa>

but this is working in ESXi 6.0 only... in 5.5 i have warning:

"Error: Unknown command or namespace storage core device physical"

And check this post:

How to identify the HDD type / Serialnr

There is explanation about fdisk -l command.

In my case this not working. Maybe because we have GPT partition.

I tried find some nice command for example:

esxcfg-info -s but there too i dont see serial numbers.

In VSAN troubleshooting guide you have additional information if you use HP:

Then you can use tool: hpssacli

Thank you for the response. It looks like 5.5.x doesn't have "physical" namespace . This may be introduced from 6.x

Thank you for the blog. That looks to be resolving the question.

Also esxcli storage core path list command also provides the HDD slot by looking at the target details.

Thanks again,
