Steps for setting up the alternate sysplex root for the dynamic replacement of the current sysplex root z/OS UNIX System Services Planning GA32-0884-00 |
|
About this taskBefore you begin: You need to ensure that the alternate sysplex root does not reside in the same volume, device, and control unit as the current sysplex root. To minimize the single point of failure, the alternate sysplex root file system should be a different PFS type than that of the current sysplex root file system. ProcedureResultsWhen you are done, you have established an alternate sysplex root in the shared file system configuration. The alternate sysplex root is mounted in read-only mode at the specified mount point and designated as AUTOMOVE. When the alternate sysplex root becomes the current sysplex root, it is mounted in read-only mode and designated as AUTOMOVE regardless of the current sysplex root settings. Requirement: If you make changes to the current
sysplex root after the alternate sysplex root was established, you
must make the same changes to the alternate sysplex root as well.
