Creating the sysplex root file system
The sysplex root is a file system that is used as the sysplex-wide root. This file system must be initially mounted read/write and designated AUTOMOVE. (See Customizing BPXPRMxx for a shared file system for a description of the AUTOMOVE parameter in BPXPRMxx.) Only one sysplex root is allowed for all systems participating in a shared file system.
- For the zFS file system, it is created by invoking the BPXISYZR job in SYS1.SAMPLIB.
- For the HFS file system, it is created by invoking the BPXISYSR sample job in SYS1.SAMPLIB.
No files or code reside in the sysplex root file system. It consists of directories and symbolic links only, and hence the size of the data set representing the sysplex root is very small.
The sysplex root provides access to all directories. Each system in a sysplex can access directories through the symbolic links that are provided. Essentially, the sysplex root provides redirection to the appropriate directories.
- Use the TSO UNMOUNT command to remount the read-only file system to read/write mode.
- Create the new directories.
- Remount the file system in read-only mode.
