CICS Liberty servers are unable to tolerate changing zFS mount points

Every CICS JVMserver region has to shut down when an lpar holding the HFS mount point is IPL'd and the mount point gets moved to another lpar. Having to shut down all these regions would defeat the purpose of a CICSPlex for high availability. which is a requirement of our client.

    We have assessed this requirement. We have no current plans for this to be implemented and so this requirement is being declined at this point. The requirement will be kept in the RFE system and might be reassessed in the future. You also have an opportunity to resubmit in twelve months time if you wish it to be reconsidered then.
