#requires -Version 3 function Get-RubrikVgfClusterStorage { <# .SYNOPSIS Returns cluster free space in the case of Volume Group format upgrade .DESCRIPTION The Get-RubrikVgfClusterStorage cmdlet is used to return projected space consumption on any number of volume groups if they are migrated to use the new format, and the cluster free space before and after the migration. If no Volume Group ID or list of ID is given, it will report the projected space consumption of migrating all Volume Groups that are currently using the old format. .NOTES Written by Feng Lu for community usage github: fenglu42 .LINK https://rubrik.gitbook.io/rubrik-sdk-for-powershell/command-documentation/reference/get-rubrikvgfclusterstorage .EXAMPLE Get-RubrikVgfClusterStorage -VGList VolumeGroup:::e0a04776-ab8e-45d4-8501-8da658221d74, VolumeGroup:::9136a7ef-4ad2-4bb9-bf28-961fb74d4322 This will return projected space consumption on volume groups within the given Volume Group ID list, and cluster free space before and after migration. .EXAMPLE Get-RubrikVgfClusterStorage This will return projected space consumption of migrating all old-format volume groups on the Rubrik cluster, and cluster free space before and after migration. .EXAMPLE Get-RubrikVgfClusterStorage -Hostname 'Server1' This will return projected space consumption of migrating all old-format volume groups from host "Server1", and cluster free space before and after migration. .EXAMPLE Get-RubrikVgfClusterStorage -Hostname 'Server1' -SLA Gold This will return projected space consumption of migrating all old-format volume groups of "Server1" that are protected by the Gold SLA Domain, and cluster free space before and after migration. .EXAMPLE Get-RubrikVgfClusterStorage -Relic This will return projected space consumption of migrating all old-format, removed volume groups that were formerly protected by Rubrik, and cluster free space before and after migration. .EXAMPLE Get-RubrikVgfClusterStorage -FailedLastSnapshot This will return projected space consumption of migrating all old-format volume groups that needs to be migrated to use fast VHDX format since they have failed the latest snapshot using the legacy backup format, and cluster free space before and after migration. .EXAMPLE Get-RubrikVgfClusterStorage -Id VolumeGroup:::205b0b65-b90c-48c5-9cab-66b95ed18c0f This will return projected space consumption for the specified VolumeGroup ID, and 0 if this Volume Group uses fast VHDX format (no need for migration). #> [CmdletBinding()] Param( # Name of the volume group [Parameter(Position = 0,ValueFromPipelineByPropertyName = $true)] [Alias('VolumeGroup')] [String]$name, # List of Volume Group IDs [String[]]$VGList, # Prefix of Volume Group names [String]$NamePrefix, # Filter results by hostname [String]$hostname, # Prefix of host names [String]$HostnamePrefix, # Filter results to include only relic (removed) volume groups [Alias('is_relic')] [Switch]$Relic, # SLA Domain policy assigned to the volume group [String]$SLA, # Filter the report information based on the primarycluster_id of the primary Rubrik cluster.
