.............snip We are in the planning stages of implementing GDPS/XRC. We have z/OS, z/VM, and Linux on zSeries (running as guests on z/VM). z/VM is at 5.3 installed on CKD. Linux is SLES9 SP3 installed on CKD and SCSI. CKD for / (root) and SCSI for "user" data. The SCSI is via EDEV.
From what I've read it appears that Linux for zSeries is supported by XRC (on CKD - which means I'll need to convert off SCSI), but I can't quite determine if z/VM is supported. I've searched the LISTSERV archives and found where folks have been discussing this very issue...but I'm still unsure about z/VM. If z/VM isn't supported, must the Linux volumes be "dedicated" to the guest? ..................snip Susan, Z/VM volumes are currently supported by XRC (take care of the upgrade level of your Z/os system....). As per the absence of a valid timestamp in some z/VM (and Linux too....) IOs, XRC will issue warning messages... but all goes ok... As a suggestion, keep z/VM and Linux volumes in a separate SDM, to avoid problems on consistency groups, due to null timestamps.... Hope this helps. regards. _________________________________________________________________________ Paolo Cacciari Business Continuity and Resiliency Services, IBM Global Services - South Region, EMEA Via Darwin 85, 20019 Settimo Milanese(MI) – Italy - MISET001 "The goal is to be prepared for a disaster not to continually plan for a successful test" * [EMAIL PROTECTED] ( + 39 051 41.36799 Mobile: + 39 335 6287584 7 + 39 02 596.23288 Fax BO: + 39 051 406052
