2.26 About Virtual Copy Management
3PAR Management Plug-In and Recovery Manager 2.1.0 for VMware vSphere User’s Guide
■ The virtual copy set name (optional).
■ The number of virtual copy volumes in the virtual copy.
■ A list of pairs (source volume, virtual copy volume). Each pair can have a list of virtual disks
and/or VM names.
All virtual copies are organized in the browser based on their creation times. The browser
displays all relevant metadata so that you can make restore decisions faster and without
actually mounting virtual copy volumes.
The data shown in the virtual copy browser comes from the metadata repository and may not
reflect the current state of InServ Storage Server. It is possible that volumes shown in the
browser may not exist in the InServ Storage Server; for example, if a volume is deleted.
For information about viewing the Virtual Copy browser, see Figure 5-12. Viewing the Alerts
on page 5.12.
2.7.6 VMFS Snapshots
In order to maintain a VM consistent virtual copy, a VMFS snapshot will be created before
creating a 3PAR virtual copy and the VMFS copy will be deleted when the 3PAR virtual copy is
created. 3PAR virtual copies and VMFS snapshots cannot coexist. 3PAR virtual copy creation will
fail if there are pre-existing VMFS snapshots for the VM.
NOTE: In order to maintain a VM consistent virtual copy, a VMFS snapshot will be
created before creating a 3PAR virtual copy and the VMFS copy will be deleted
when the 3PAR virtual copy is created. 3PAR virtual copies and VMFS snapshots
cannot coexist. 3PAR virtual copy creation will fail if there are pre-existing VMFS
snapshots for the VM.
When creating a VMFS snapshot, VMware can fail the operation with the
message: “Cannot create a quiesced snapshot because the create snapshot
operation exceeded the time limit for holding off I/O in the frozen virtual
machine.”
If this message is displayed, the VMware Tools process should be restarted, or
reinstalled to resolve the issue.
