The storage volumes are formatted with a 64 KB allocation unit to maximize the disk performance. Initialize and format the storage volumes on all the database server nodes by running the PowerShell commands in the following procedure.
Note: Ensure that both the database servers are assigned the same drive letter for a LUN.
Get-Disk | where-object Isoffline -eq $True
Initialize-Disk -Number 1 -PartitionStyle MBR
New-Partition -DiskNumber 1 -DriveLetter 'E' –UseMaximumSize
