Code:
<# Microsoft_Clustered_Disks_Creation_V0.10.ps1
Purpose:
This snippet streamlines the process of creating physical disk volumes on a Windows host and automatically add them into an existing Microsoft cluster
What this script does:
- Automatically formats a list of pre-defined disks with user-specified cluster sizes
- Assigns available drive letters as paths to newly created volumes
- Systematically adds new disks into a Microsoft Cluster as Physical Disks with correct labels
Limitations:
- Currently, this program cannot reliably sets unitialized disks as online or offline. Thus, prior to starting this script,
the admin must set disks as online MANUALLY; otherwise, such disks will be skipped
- This script doesn't fix weird problems at the LUN protocol level, as fixing that requires a re-creation of the LUN volumes.
Additional troubleshooting documentation:
using diskpart (manual):
SELECT DISK 2
ONLINE DISK
CLEAN
CREATE PARTITION PRIMARY
FORMAT FS=NTFS UNIT=16K QUICK
ASSIGN LETTER=B #Change B to any other available access-path letter
ACTIVE
EXIT
Add to Cluster (manual):
$numero=7
$etiqueta="LUN007"
Get-Disk -Number $numero | Add-ClusterDisk | %{$_.Name=$etiqueta }
