I’m running VSAN in a nested configuration, and I generally shutdown my homelab in the evening each day. I grew tired of doing the manual process of maintenance mode for these nested nodes before shutting them down, and then shutting down the host that they run on. I did a bit of googling for the PowersHell that does that – and was see quite complicated scripts. I’m pleased I went back to the documentation for PowerCLI which is the primary source for the cmdlets:
https://code.vmware.com/doc/preview?id=6702#/doc/Set-VMHost.html
I discovered that the Set-VMhost cmdlet supports a -VsanDataMigrationMode switch with three different options for:
- Full
- EnsureAccessibility
- NoDataMigration
1..4 | Foreach {
$Num = "{0:00}" -f $_
Set-VMHost -VMHost esx"$Num"nj.corp.local -State "Maintenance" -VsanDataMigrationMode NoDataMigration
}
1..4 | Foreach {
$Num = "{0:00}" -f $_
Stop-VMHost esx"$Num"nj.corp.local -Confirm:$False
}
