Removing paths using DS CLI

Complete this task to remove paths between the LSSs on the source storage unit and the target LSSs on the target storage units.

Before you delete paths, review the paths that are currently established.

If you delete all paths, you lose the communication between your remote mirror and copy volume pairs. All paths between the source LSS and target LSS are removed.

Perform the following steps to remove the paths between the source and target LSSs with DS CLI commands. 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 –dev IBM.1750-68FA120 01
```
The report that displays from this command provides the worldwide node name (WWNN) that is used with the rmpprcpath command.
Issue the rmpprcpath command to remove the paths between all source and target pairs. 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
```
Note:
- The -remotedev parameter specifies the ID of the secondary storage unit.
- The -remotewwnn parameter must specify the WWNN of the secondary storage unit. If you specify the WWNN of the primary storage unit, the command fails.
- If you do not specify the fully qualified -dev and -remotedev parameters, you must use the fully qualified source_LSS_ID:target_LSS_ID value. For example: IBM.1750-68FA120/01:IBM.1750-68FA150/01
  The fully qualified source_LSS_ID:target_LSS_ID value must be the last parameter in your command.
A confirmation message is displayed for each path that is being removed.
Enter Y to confirm that you want to remove the specified remote mirror and copy path. A message similar to the following appears for each remote mirror and copy path that is being removed when you process the rmpprcpath command.
```
Are you sure you want to delete PPRC path (whatever was designated)?
 [y/n]: Y
PPRC path (designated in the command) successfully deleted.
```
Repeat Step 2 for all the remote mirror and copy paths that you want removed from the same source LSS to a different target LSS.
