Steps for removing the alternate sysplex root support

About this task

This topic shows how to remove support for the alternate sysplex root.

Perform the following steps to remove the alternate sysplex root support.

Procedure

In the BPXPRMxx parmlib member, replace the ALTROOT FILESYSTEM statement with the following statement:
```
ALTROOT NONE
```
Because the ALTROOT NONE and ALTROOT FILESYSTEM statements are mutually exclusive, only one can be specified in the BPXPRMxx parmlib member.

If concatenating parmlib members result in multiple ALTROOT statements, then the first parmlib member specified on the OMVS= operator command that contains the ALTROOT statement will take effect.

_______________________________________________________________
Issue a SET OMVS operator command to process the ALTROOT NONE statement. For example:
```
SET OMVS=(XX)
```

Results

When you are done, you have removed the alternate sysplex root support and deleted any outstanding BPXF253E messages. The alternate sysplex root file system can be left mounted as a regular file system on all systems in the sysplex. If you need to reestablish the alternate sysplex root support with the same file system name, the file system will have to be unmounted globally before it can be used in the ALTROOT FILESYSTEM statement.

Use your preferred unmount method to unmount the alternate sysplex root.
