HP 3PAR Application Software Suite for VMware - Manual (Page 23)

•
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 HP 3PAR Storage System. It is possible that volumes shown in the browser
may not exist in the HP 3PAR Storage System; for example, if a volume is deleted.
For information about viewing the Virtual Copy browser, see Figure 41 (page 54) .
VMFS Snapshots
In order to maintain a VM consistent virtual copy, a VMFS snapshot will be created before creating
an HP 3PAR virtual copy and the VMFS copy will be deleted when the HP 3PAR virtual copy is
created. HP 3PAR virtual copies and VMFS snapshots cannot coexist. HP 3PAR virtual copy creation
in VM, Datastore, or Remote Copy will fail if there are preexisting VMFS snapshots for the VM.
NOTE: 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.
Scheduling Tool
You can automatically have virtual copies created according to a specified schedule by using the
scheduling tool (see
“Scheduling Virtual Copies” (page 66) for details). You have the option of
scheduling when (hourly, daily, weekly, monthly) the virtual copy is to be created and then specifying
how often the task is to be performed. You can also schedule a virtual copy creation task to occur
on a one-time basis.
Host Explorer
Host Explorer for VMware communicates with the storage server over a TCP/IP connection and
provides detailed host configuration information. You can start the service and configure settings
through the Host Explorer tab available from the RMVMware Admin Tool GUI interface (see
“Host
Explorer Tab” (page 38) for details).
VASA Support
Support is included for vSphere Storage APIs for Storage Awareness (VASA) that allows a VMware
administrators to view information about the physical storage array as well as the virtual data
store. For instance, you can get performance statistics from within vCenter associated with a LUN
on HP 3PAR disk arrays. For more information on VASA, refer to "Storage Providers" in vCenter
Server.
