When you define virtual disks for the SAN Volume Controller and the Storwize® V7000 storage
devices, you can use either the graphical user interface or the command-line
interface.
Before you begin
Before you start defining virtual disks, verify that the following
prerequisites are met:
- A storage area network is available.
- Storage disks are attached and available in the SAN Volume Controller or Storwize V7000 environment.
- Subsystem Device Driver (SDD) or Subsystem
Device Driver Path Control Module (SDDPCM) is installed and available
on the host systems.
- A cluster is available in the SAN Volume Controller or Storwize V7000 environment.
- Each host has at least two paths to the SAN Volume Controller or Storwize V7000 storage
device.
Procedure
To create virtual disks on the production server and backup server, complete
the following steps.
- From the graphical user interface, select . The
virtual disks are created by using the managed disk group.
- Map the virtual disk to the hosts that are created for
the production server. To map the virtual disks to the backup server,
in the Tivoli® Storage FlashCopy® Manager profile
file, configure the BACKUP_HOST_NAME parameter
by assigning one of the following values:
- Assign the value PREASSIGNED_VOLUMES to use
a static predefined map.
- Assign the backup_server_hostname to allow Tivoli Storage FlashCopy Manager to
dynamically map the target virtual disks when needed.
- Define the TARGET_VOLUME parameter
in the target volumes file (.fct). This
name is specified by the parameter with the appropriate virtual disk names of
the target LUNs in the profile configuration file. For
example:
TARGET_VOLUME A01pro1_1_t1
TARGET_VOLUME A01pro1_2_t1
In this example, the source
volume names are A01pro1_1 and A01pro1_2 with
target set named 1. Alternatively,
you can define the target names by using the TARGET_NAMING parameter
in the Tivoli Storage FlashCopy Manager profile
file.
