Renaming Cluster Available Disk

Open Discussions

Hello PS Community,

I am attempting to rename multiple cluster available disk on Windows Server 2022 server. Cluster Available Disk will be added as a mount point inside a single drive.

These are cluster available disk

These are their volume labels because they will not be assigned a drive letter.

Once added inside Failover Cluster as shown below.

Now, I want to rename them in bulk based on their file system label . I cannot find a away to tie together a disk i.e. ‘Cluster Disk X‘ with any other attribute i.e. Disk Number , ID etc. via PowerShell command in such a that If Disk Physical Number is 5 then then its label/name inside Available Cluster Storage should be ‘XXXX’ file system label or match its volume label as shown earlier.

Is there a way to rename in bulk Cluster Available Disk based on its file system label.

There is an Access Modifiers but it is a manual process. I have to manually match ‘Cluster Disk X‘ with Disk Number to assign a label. I have to match physical disk number with ‘‘Cluster Disk X‘ as shown below.

$ClusterDisk1 = Get-ClusterResource -Name ‘Cluster Disk 1’

$ClusterDisk1.Name = ‘AppVol’

But this is a manual and error prone process. I want to rename it in bulk.

It’s surprisingly difficult to map volumes to disk/partition. Here is the best thing I could come up with over the years. (I used to just make best guess effort based on disk capacity)

$diskdrivelist = Get-CimInstance Win32_Diskdrive -Filter "Partitions>0" 

$output = foreach($diskdrive in $diskdrivelist){
    $diskpartitionlist = Get-CimInstance -Namespace "root\cimv2" -Query  "ASSOCIATORS OF {Win32_DiskDrive.DeviceID='$($diskdrive.deviceid)'} WHERE AssocClass = Win32_DiskDriveToDiskPartition"

    foreach($diskpartition in $diskpartitionlist){
        $logicaldisklist = Get-CimInstance -Namespace "root\cimv2" -Query  "ASSOCIATORS OF {Win32_DiskPartition.DeviceID='$($diskpartition.DeviceID)'} WHERE AssocClass = Win32_LogicalDiskToPartition"

        foreach($logicaldisk in $logicaldisklist) {
       
            [PSCustomObject]@{
                ComputerName        = $env:COMPUTERNAME
                Date                = (Get-Date).ToString('o')
                Size                = $logicaldisk.Size
                Free                = $logicaldisk.FreeSpace
                Partition           = $diskpartition.Name
                DiskIndex           = $diskpartition.DiskIndex
                DriveLetter         = $logicaldisk.Name
                Description         = $diskdrive.Description
                DeviceID            = $diskdrive.DeviceID
                DeviceModel         = $diskdrive.Model
                FileSystem          = $logicaldisk.FileSystem
                Compressed          = $logicaldisk.Compressed
                VolumeDirty         = $logicaldisk.VolumeDirty
                VolumeName          = $logicaldisk.VolumeName
                VolumeSerialNumber  = $logicaldisk.VolumeSerialNumber
                MediaType           = $diskdrive.MediaType
            }
        }
    }
}

With the limited info you get from the cluster side, I think the Number can be correlated to the DiskIndex of the logical disk. If so, the VolumeName should be what you want to rename it to.

See if this seems to match on your end

$available = Get-ClusterAvailableDisk

foreach($disk in $available){
    $current = $output | where diskindex -eq $disk.number

    Write-Host "Cluster disk '$($disk.Name)' is volume '$($current.VolumeName)'" -ForegroundColor Cyan
}

If so you can grab this info before adding them to the cluster to use for renaming after.

$listwithclustername = foreach($disk in $available){
    $current = $output | where diskindex -eq $disk.number

    $current | Add-Member -NotePropertyName ClusterName -NotePropertyValue $disk.Name
    $current | Add-Member -NotePropertyName ClusterId -NotePropertyValue $disk.Id
    $current | Add-Member -NotePropertyName Partitions -NotePropertyValue $disk.Partitions -PassThru
}

Thanks for your response.

Looking at this section of the script I found that it may not work.

$available = Get-ClusterAvailableDisk

foreach($disk in $available){
    $current = $output | where diskindex -eq $disk.number

    Write-Host "Cluster disk '$($disk.Name)' is volume '$($current.VolumeName)'" -ForegroundColor Cyan
}

I will explain the reason why. Get-ClusterAvailableDisk does not work once I add all disks inside Failover Cluster Manager and If ran again it draws blank. Following output shows disks NOT added into Failover Cluster Manager yet.

PS C:\> Get-ClusterAvailableDisk | Sort-Object Number | FT -AutoSize

When I add them into Failover Cluster Manager, they disappear from Get-ClusterAvailableDisk output. It only appears in the following command then

PS C:\> Get-ClusterResource | Sort-Object Name

Name                     State   OwnerGroup        ResourceType

Cluster Disk 8           Online  Available Storage Physical Disk
Cluster Disk 9           Online  Available Storage Physical Disk

Running following command draws blank

Get-ClusterAvailableDisk | Sort-Object Number | FT -AutoSize

Therefore, the snippet I pasted in this response cannot work and problem of finding a relationship between Disk number and its association inside following command draws blank too which leads to unable to label disk inside Failover Cluster by matching its Disk number etc.

Get-ClusterResource | Sort-Object Name

I hope that I am able to communicate my understanding . :slight_smile:

I said you have to do this before adding them.
