IBM Tivoli Storage FlashCopy Manager for UNIX and Linux, Version 4.1

LVM mirroring and ASM failure group environments

In a Logical Volume Manager (LVM) mirroring on AIX® and Oracle Automatic Storage Management (ASM) failure group environments, multiple DEVICE_CLASS configuration sections are required. One section per storage cluster or LVM mirror is required.

The storage system ID must be specified in the Tivoli® Storage FlashCopy® Manager DEVICE_CLASS configuration section. For example:

>>> DEVICE_CLASS MIRR_1
COPYSERVICES_HARDWARE_TYPE 		DS8000 
COPYSERVICES_PRIMARY_SERVERNAME 	DS8000_1 
STORAGE_SYSTEM_ID 		7513158
TARGET_SETS 				VOLUMES_FILE
VOLUMES_FILE 				<name of target set definition file 1>
FLASHCOPY_TYPE 				INCR
<<<	
>>> DEVICE_CLASS MIRR_2
COPYSERVICES_HARDWARE_TYPE 		DS8000 
COPYSERVICES_PRIMARY_SERVERNAME 	DS8000_2 
STORAGE_SYSTEM_ID 		7512067
TARGET_SETS 				VOLUMES_FILE
VOLUMES_FILE 				<name of target set definition file 2>
FLASHCOPY_TYPE 				INCR
<<<

The STORAGE_SYSTEM_ID parameter is required when ASM failure groups are distributed across multiple storage devices. Each device section in the profile requires this parameter to specify the storage subsystem ID. Do not specify this parameter when all failure groups are on the same storage subsystem. For information about this parameter, see the DEVICE_CLASS device section of the profile configuration file.
