Mounting VSS Snapshots and Volumes
HPE VSS Services enables application-consistent snapshots for Microsoft
Exchange and SQL Server. When a VSS snapshot is taken, several flags and attributes are set on
the snapshot, and volumes cloned, promoted, or restored from that snapshot will inherit those
flags and attributes. Before either a VSS snapshot or a volume cloned, promoted, or restored
from a VSS snapshot can be properly mounted on a Windows host or cluster, the flags and
attributes must be reset using the Set-NimVolume
PowerShell
cmdlet.
Using the Set-NimVolume
PowerShell cmdlet is an additional step in the
volume mounting workflow only when mounting a VSS snapshot, or a volume cloned, promoted, or
restored from a VSS snapshot; mounting other types of volumes do not require the additional
step.
To use the Set-NimVolume
PowerShell cmdlet, you must know the snapshot or
volume serial number or disk ID (Windows-assigned ID). Use one of the following methods to get
this information:
- Use the PowerShell Get-NimVolume cmdlet to obtain the serial number or disk ID.
- Use piping with the
Set-NimVolume
andGet-NimVolume
cmdlets.
The following three scenarios demonstrate where in the process you would use the
Set-NimVolume
PowerShell cmdlet when mounting a volume cloned or promoted
from VSS snapshots.
