LDEVs for which virtualization management is enabled
LDEVs that satisfy one of these conditions:
•
The model name and serial number of the virtual storage machine that manages a resource
group with LDEVs is different than the storage system involved in the operation.
•
The model name and serial number of the virtual storage machine that manages a resource
group with LDEVs is the same as the storage system involved in the operation. Yet, the values
of the virtual LDEV ID and the LDEV ID are different.
Provisioning operations for resources in a virtual storage machine
For provisioning operations that involve virtualized resources in a virtual storage machine, you
can perform provisioning operations that specify conventional physical resources or virtualized
resources. However, provisioning operations that specify IDs of virtualized resources are limited.
For details about data management operations for virtualized resources, see HP XP7 RAID Manager
User Guide.
Maintenance operations for resources in a virtual storage machine
Maintenance operations can be be performed only on IDs of physical resources. Maintenance
operations cannot be performed on IDs of virutalized resources in a virtual storage machine. For
example, you cannot perform maintenance operations by specifying virtual LDEV IDs.
Pair operations with virtual storage machine pairs
Specifying virtual IDs in pair operations
You can perform pair operations by specifying both of the following in the HORCM_LDEV
parameters of the RAID Manager configuration definition file:
•
Serial number of the virtual storage machine in Serial#
•
Virtual LDEV number in CU:LDEV(LDEV#)
You can perform conventional pair operations by specifying both of the following in the
HORCM_LDEV parameters of the configuration definition file:
•
Serial number of the physical storage system in Serial#
•
Physical LDEV number in CU:LDEV(LDEV#)
CAUTION: If the following condition exists, the local copy pair operation cannot be performed
by specifying virtual IDs:
•
Primary volume and secondary volume are defined differently for the virtual storage machine.
If both of the following conditions exist, remote copy pair operations cannot be performed by
specifying virtual IDs:
•
Primary volume is an LDEV of VSP, HUS VM, USP V, or USP VM
•
Secondary volume is an LDEV of VSP G1000.
Displaying pair information
You can create pairs by specifying both of following in the HORCM_LDEV parameters of the RAID
Manager configuration definition file:
•
Serial number of the physical storage system in Serial#
•
Virtual LDEV number in CU:LDEV(LDEV#)
