Description
Term
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 the HP XP7 RAID
Manager User Guide.
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 the
Serial#
parameter
•
Virtual LDEV number in the
CU:LDEV(LDEV#)
parameter
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 the
Serial#
parameter
•
Physical LDEV number in the
CU:LDEV(LDEV#)
parameter
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 P9500, XP24000 Disk Array, or XP20000 Disk Array
•
Secondary volume is an LDEV of HP XP7 Storage.
CAUTION:
The High Availability pair operation that specifies the virtual ID cannot be performed.
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 the
Serial#
parameter
•
Virtual LDEV number in the
CU:LDEV(LDEV#)
parameter
If the pair is created under the above conditions, the following are displayed as results of executing
the pairdisplay command:
•
Serial number of the virtual storage machine in the
Seq#
parameter
•
Virtual LDEV number in the
LDEV#
parameter
