Removing the fibre-channel paths

Complete this task to remove the fibre-channel paths between all Global Mirror source and target pairs and between the master and subordinate storage units. This is the fifth and final 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.
Close 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.
Remove the Global Copy relationships that exist with the volumes that were part of your Global Mirror environment.

Repeat the process to remove the fibre-channel paths for each data path and for each control path. Data paths consists of source LSSs on the storage images at the primary site and target LSSs on the storage images at the secondary site. Control paths consist of the master storage image LSS and the subordinate storage image LSSs.

Perform the following steps to remove the fibre-channel paths between all Global Mirror source and target pairs and between the master and subordinate storage units. 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 lspprcpath command to display a list of existing remote mirror and copy path definitions. Enter the lspprcpath command at the dscli command prompt with the following parameters and variables:
dscli>lspprcpath -dev storage_image_ID source_LSS_ID
Example
```
dscli>lspprcpath –l –dev IBM.1750-68FA120 01
```
Note: The report that is displayed from this command provides the worldwide node name that is used with the rmpprcpath command.
Record the path information to use when you issue the rmpprcpath command.
Issue the rmpprcpath command to remove the fibre-channel paths between all Global Mirror source and target pairs and between the master and subordinate storage units. Do this for each path that must be removed. Enter the rmpprcpath command at the dscli command prompt with the following parameters and variables:
dscli>rmpprcpath -dev storage_image_ID -remotedev storage_image_ID -remotewwnn wwnn source_LSS_ID:target_LSS_ID

Example
```
dscli>rmpprcpath -dev IBM.1750-68FA120 -remotedev IBM.1750-68FA150
-remotewwnn 12341234000A000F  01:01
```
Enter Y in response to each message to confirm that you want to remove the specified remote mirror and copy path. A message similar to the following is displayed for each remote mirror and copy path that is being removed.
```
Are you sure you want to delete the Remote Mirror and Copy path 
(whatever was designated)? [y/n]: Y

Remote Mirror and Copy path (designated in the command) successfully deleted.
```
Note: Use of the -quiet parameter with the rmpprcpath command turns off the confirmation question for each path that is being removed.
Repeat Step 3 for all the remote mirror and copy paths per LSS that were part of your Global Mirror environment.

After this task is complete, you can create your new Global Mirror environment and configuration.
