the volume. Recovery Manager for VMware vSphere stores the details of all virtual disks and VMs
present in the Datastore.
This feature has the following restrictions:
•
The Datastore must be on exactly one HP 3PAR volume. A Datastore that spans across more
than one LUN is not supported.
•
RDM LUNs defined in the Datastore are not included in the Recovery Set. It is possible that a
HP 3PAR LUN is used as RDM in a guest OS, which is defined in a Datastore created on
another HP 3PAR LUN.
NOTE: A Recovery Set of a Datastore does not include any RDM 3PAR LUNs.
•
All Datastore Recovery Sets can be VM or crash consistent. File system and/or application
integrity checks must be performed in the guest OS for the crash consistent Recovery Sets after
restoration.
•
Network File System (NFS) Datastores are not supported.
•
VMFS file systems spanning multiple hard disk partitions to create a single logical volume are
not supported.
•
The Datastore must not be on an ESXi SAN boot disk. Recovery Set operations are not
supported on Datastores residing in ESXi SAN boot disks.
Virtual Machine Recovery Sets
A Virtual Machine (VM) configuration files are created in a Datastore. VMDK virtual disks used
by VMs are created on one or more Datastores. In addition, a VM can use HP 3PAR volumes
directly as RDM virtual disks. Recovery Manager for VMware vSphere identifies all of the HP 3PAR
volumes used by a VM and creates Recovery Sets of all of them simultaneously. A list of virtual
disk names and their type (RDM or VMDK) and configuration file name are also recorded in the
repository during Recovery Set creation.
A VM Recovery Set has the following restrictions:
•
Virtual disks used by a VM must be from the HP 3PAR Datastore, and the latter must satisfy
the conditions mentioned in
“Datastore Recovery Sets” (page 15) .
•
If the VM uses more than one HP 3PAR volume, all of them must be from the same HP 3PAR
storage array.
•
VMs that use a mix of HP 3PAR LUNs and third party LUNs are not supported.
•
All VM Recovery Sets can be VM or crash consistent. File system and/or application integrity
checks must be performed in the guest OS after restoration for the crash consistent Recovery
Sets.
•
VMs using NFS Datastores are not permitted.
•
VMFS file systems spanning multiple hard disk partitions to create a single logical volume are
not supported.
Remote Recovery Sets
Remote Recovery Sets are based on the Remote Copy Group. If a VM or Datastore uses virtual
volumes outside of the Remote Copy group, HP 3PAR Recovery Manager for VMware vSphere
cannot take a remote Recovery Set of the group. Remote Recovery Sets require a remote host with
TCP/IP connectivity to the target Storage System.
•
VMs or Datastores must be contained within the Remote Copy group
•
Restore processes are currently performed manually
