Complete this task to remove Global Copy relationships that existed
with the volumes that were part of your Global Mirror environment. This task
is the fourth step in removing the Global Mirror environment from your system.
Ensure that you have completed the following tasks before you initiate
this task; otherwise, this task fails:
- Remove the volumes that are associated with each Global Mirror session
that you have closed.
- End the Global Mirror sessions that are part of your Global Mirror environment.
- Remove FlashCopy relationships that exist with the volumes that were part
of your Global Mirror environment.
The purpose of this task is to remove the Global Copy relationships
for each pair of source volumes on your primary site and the target volumes
on your secondary site. There might be several LSSs that are involved and
the Global Copy relationships must be removed within each LSS. This requires
that you issue the rmpprc command for each LSS until all relationships
are removed.
Perform the following steps to remove Global Copy pair
relationships that exist with the volumes that were part of your Global Mirror
environment. The example commands in this task are shown in two formats. The
first format shows the type of information the command requires. The second
format provides the command with declared values for the variables.
- Issue the lspprc command to check the status information
for each Global Copy volume relationship in the list. Enter the lspprc command
at the dscli command prompt with the parameters and variables shown as follows:
dscli>lspprc -dev storage_image_ID -remotedev storage_image_ID -l SourceVolumeID:TargetVolumeID.
Example
dscli>lspprc -dev IBM.2107-68FA120 -remotedev IBM.2107-68FA150 -l 0100:0100
Use the -l parameter to provide a more detailed report about
the Global Copy volume relationships.
- Analyze the list of volumes that have been part of your Global
Mirror environment, and ensure that these are the volumes from which the Global
Copy relationships must be removed.
- Issue the rmpprc command to remove the Global Copy volume
relationships. Enter the rmpprc command at the dscli command prompt
with the following parameters and variables:
dscli>rmpprc -dev storage_image_ID -remotedev storage_image_ID SourceVolumeID:TargetVolumeID
Example
dscli>rmpprc -dev IBM.1750-68FA120 -remotedev IBM.1750-68FA150 0100:0100
- Enter Y in response to each message to confirm that you
want to remove the specified Global Copy pair. A message similar to the following
is displayed for each Global Copy pair that is being removed when you process
the rmflash command.
Are you sure you want to remove PPRC pair 0100:0100? [y/n]: Y
Remote Mirror and Copy pair IBM.1750-68FA120/0100:0100
successfully removed.
- Repeat Steps 3 and 4 for all the volumes that have
Global Copy relationships in the LSSs that were part of your Global Mirror
environment.
