Script to set a LUN as perennially reserved

[MRoushdy]

Hello,

I have more than 30 physical RDM LUNS mapped to more than 25 hosts, I need a script please to read from CSV (or any other suitable file format) to read the LUN unique ID and the host name please, the purpose of the script is to set all of the LUNs as perennially reserved

like this command:

esxcli storage core device setconfig -d naa.id --perennially-reserved=true

You could do something like this.

It assumes the CSV contains 2 columns like this

VMHost,CanonicalName

Import-Csv -Path .\lun.csv -UseCulture | %{

    $esxcli = Get-EsxCli -VMHost $_.VMHost

    $esxcli.storage.core.device.setconfig($false,$_.CanonicalName,$true)

    $esxcli.storage.core.device.list($_.CanonicalName) |

    Select @{N="Time";E={"{0:g}" -f (Get-Date).TimeOfDay}},Device,IsPerenniallyReserved

}
