fetches all eligible disks (unclaimed) info

[bright_terry]

hi guys

please am trying to fetches all eligible disks (unclaimed) info that can be utilized to create a VSAN disk
group.

and  should also be able to fetch info of all the eligible disks in vcenter with details
including Canonical Name of disk, linked Hosts.

below is the required output i wish to get 

Disk type (Cache disk/ Capacity disk),

• Drive type( Flash / HDD),
• canonical name of the disk 
• cluster name linked to.
• Host it is linked with.

Have a look at the PowerCLI Cookbook for VSAN, more specifically page 34.

Thank you so much this was so helpful as i can now see most of the fields i needed, but my only problem is some of the other fields are not showing when i use 

Get-VMHost -Name $ESXiHost | Get-VMHostHba | Get-ScsiLun | Where-Object {$_.VsanStatus -eq “Eligible”} | format-list 

drivetype, disktype are messing, is there a way i can get this using powercli

[LucD]

The DriveType is found in the IsSsd property.
Not sure what you mean by DiskType

[bright_terry]

on the isssd property is there a way i can select Disktype: (Cache disk/ Capacity disk)

and when i say drive type this is what i mean: Drive type( Flash / HDD),

When you are looking for eligible disks, there is no indication of Cache or Capacity yet.
That is only available for disks that are already used for VSAN.

You can test the IsSsd property and return the desired text.
For example, in a calculated property you could do

Get-VMHost -Name $VMHost |
Get-VMHostHba | Get-ScsiLun |
 Where-Object { $_.VsanStatus -eq "InEligible" } |
Select CanonicalName,CapacityGB,MultipathPolicy,
	@{N='Type';E={if($_.IsSsd){'Flash'}else{'HDD'}}}

Thank you, this worked but am still finding challenges on how to know how to fetch all eligible disks (unclaimed) info using exsi and cluster.

[LucD · Accepted solution]

You could do

Get-Cluster -PipelineVariable cluster |
Get-VMHost -PipelineVariable esx |
Get-VMHostHba | Get-ScsiLun |
Where-Object { $_.VsanStatus -eq "Eligible" } |
Select @{N='Cluster';E={$cluster.Name}},
   @{N='VMHost';E={$esx.Name}}, 
   CanonicalName,CapacityGB,MultipathPolicy,
   @{N='Type';E={if($_.IsSsd){'Flash'}else{'HDD'}}}

thank you this really worked but it print all of the disk information i just needed it to print the one attached to a particular exsi_hostname, powercli print alot of information on the screen, i wanted to print my json output so it can display on an artefact so i can easily download is there a way i can do this in powercli?

[LucD]

Not sure what you mean by "to print my JSON output"?
To limit to a specific ESXi node, drop the Get-CLuster and use the Name parameter on the Get-VMHost cmdlet.

Get-VMHost -Name <MyEsx> -PipelineVariable esx |
Get-VMHostHba | Get-ScsiLun |
Where-Object { $_.VsanStatus -eq "Eligible" } |
   Select @{N='VMHost';E={$esx.Name}}, 
   CanonicalName, CapacityGB, MultipathPolicy,
   @{N='Type';E={if($_.IsSsd){'Flash'}else{'HDD'}}} |
ConvertTo-Json

 thank you LuCD, but this was what i meant Can you please rework it so that it should be able filter on ESXI host or cluster level. Module should be able to print the unclaimed disks only for that given input cluster or esxi hosts.   and also 

i should be able to print all the invocation in the artefact output

[LucD · Accepted solution]

I have no clue what "artefact output" means.
How does that look?

You can use a Name parameter on the Get-Cluster and Get-VMHost cmdlets, which would allow you to limit the output.
