    Get Details of VSAN Cluster

    sc2317 Novice

      Hi,

      I am looking for some script or automated way to get details of VSAN cluster like number of nodes, disk groups, RAID, Disks etc. Can someone please suggest or redirect me to the tested script to fetch details of VSAN environment.

          Have you checked the Reporting Recipes chapter in Jase's paper POWERCLI COOKBOOK FOR VMWARE VSAN

            Thanks, I have checked it and fetched most of the information. However, I am still confused how to get the health status of the VSAN cluster that details if there are any issues also on VSAN cluster.

            I could see one healthcheck script "vghetto-scripts/VSANHealthChecks.ps1 at master · lamw/vghetto-scripts · GitHub ", However I am not sure if this is getting the health of the VSAN cluster. As I am going to directly run on production environment so bit reluctant to do until I am sure what it does.

            As far as I can understand it is disabling or enabling the health checks which I don't want. I am looking or health report of VSAN cluster that includes the issues if there are any.

              You can get health info in current builds of vSAN 6.6/6.7 using:

              # esxcli vsan health cluster list

              e.g.:

              [root@hostname:] esxcli vsan  health cluster list

                If you want to stay with PowerCLI, you can retrieve the same with

                 

                $clusterName = 'cluster'

                $esxcli = Get-Cluster -Name $clusterName | Get-VMHost | Get-Random | Get-EsxCli -V2

                $esxcli.vsan.health.cluster.list.Invoke()

                  Thanks, Yes I can get that, However If I want details of errorr/warning of health if its "Red". For example, by using esxcli vsan health cluster get -t="Physical disk", then I get more details. Could you please suggest if I can get that by using PowerCLI ?

                    You can get the status of an individual test by using the get method with the TestName.

                    Something like this (you specify the name of the test in the hash table.

                     

                    $esxcli.vsan.health.cluster.get.Invoke(@{test='vSAN object health'})

                     

                     

                    Be aware that sometimes not all tests are available/valid.

                    You can check which ones are available in your environment with

                     

                    $clusterName = 'cluster'

                    $esxcli = Get-Cluster -Name $clusterName | Get-VMHost | Get-Random | Get-EsxCli -V2

                    $esxcli.vsan.health.cluster.list.Invoke() |

                    ForEach-Object -Process {

                        Write-Host "$($_.HealthTestName): " -NoNewline

                        try{

                           if($esxcli.vsan.health.cluster.get.Invoke(@{test=$_.HealthTestName})){

                            Write-Host -ForegroundColor green 'ok'

                           }

                        }

                        catch{

                            Write-Host -ForegroundColor red 'nok'

                        }

                    }
