Complete this task to create a Global Mirror session. This is the
fourth step in setting up your Global Mirror environment. After you complete
this step you are ready to start Global Mirror processing.
The following tasks must be completed before you can proceed with
this step.
- Ensure that the fibre-channel paths between all Global Mirror source and
target pairs and between the master and subordinate storage units have been
created.
- Ensure that the Global Copy pairs have been created between the local
storage units and the remote storage units.
- Ensure that the FlashCopy relationships at the remote site between the
Global Copy secondary volumes and the FlashCopy target volumes have been created.
The purpose of this step is to create a container that associates
volumes with a Global Mirror session.
Perform the following steps to
create the Global Mirror session. The example commands in this task are shown
in two formats. The first format shows the type of information that the command
requires. The second format provides the command with declared values for
the variables.
- Issue the mksession command to create the Global Mirror
session. Enter the mksession command at the dscli command prompt using
the following parameters and variables:
dscli>mksession -dev storage_image_ID -lss LSS_ID -volume volume_ID Session_ID
Example
dscli>mksession -dev IBM.1750-68FA120 -lss 10 -volume 0800-0810 01
- Repeat Step 1 for each LSS.
You must make a session
for each LSS. However, you can associate each LSS with the same session. For
example: You have LSS 08 and it contains volumes 0800 - 0810. You create a
session and assign it to session 08. You also have LSS 09 and it contains
volumes 0900 - 0910. You create a session and assign it to session 08. When
you start Global Mirror processing, the volumes for LSS 8 and
LSS 9 are processed in the same session (session 08).
