I guess HDS would be the only ones that could tell you if they support Linux 
timestamps or not.   Technically, I'm pretty sure a Linux timestamp looks just 
like a z/OS timestamp.    Mabye they mean they don't support it because they 
haven't tested it.

We run GDPS/XRC which relies on the timestamps.  A separate z/os data mover for 
VM is required with the mixing of the stamped and non-stamped at the moment.  
If you need timestamped VM I/O, best to call IBM and ask.

Subject: [IBMVM] HUR

Is anyone successfully mirroring DASD using Hitachi Universal Replicator (HUR) 
for a z/VM environment with Linux guests?  I know that there are challenges 
because z/VM doesn't timestamp its I/O but Linux does.  I'm being told that HUR 
doesn't support Linux timestamps.  Is that true?  Allegedly, this lack of 
support means that a z/VM replication environment would need to be separate 
from our z/OS replication environment, including a separate z/OS LPAR to 
control the replication.
