The environment is currently running z/OS V3.1 and we plan to implement a
shared zFS file system across our SYSPLEX of four LPARs.
I am seeking step-by-step accounts from anyone who has completed a similar
implementation.
Background and findings so far:
* We have a SYSPLEX with four LPARs.
* Preliminary research indicates the following items must be addressed:
* SYSPLEX root file system configuration
* System-specific file system configuration on each LPAR
* Creation and allocation of the CDS.
* BPX parameters update - SYSPLEX(YES) SYSNAME(&SYSNAME) AUTOMOVE.
Questions and primary concern:
* What is the recommended sequence of events to enable shared zFS in a
SYSPLEX?
* Do all LPARs have to be updated or IPLed simultaneously to enable
sharing, or can this be accomplished by updating one LPAR at a time?
* Is it safe to leave the current zFS filesystems in place and then
unmount/remount the filesystems to change sharing modes when the shared
configuration is ready?
Thank You
