Hello Crispin Hugo, Mace (Larry Macioce), and Tom Duerbusch, Thank you for the info. I am on both z/VM 5.3 and z/VSE 4.1.2. I tried to wire the two racks to all have a path if we lost Full connection.
It is the two hours that worry me. I get Tuesday nights here at the Hospital. And as long it works. So what is your backup plan? What happens if you get a power failure in the middle of the update? Yea, I know UPS but I have to plan for worst case. Say in your best Germany accent 'WE WILL NOT FAIL!' (sorry Martin) Crispin, you have indicated the 3 updates. I see the SEA.JAR that I believe will update the microcode in the DS6800, I see the DS6800STorageManager_WIN_5.2.200.1678.zip (for the Windows version of Storage Manager), and DSCLI_5.2.2.411.tar.gz and DSCLI_5.2.2.411.zip which I thought was the Data Storage Command Line interface. Are these the three that you updates you are talking about? Because it would be ok to get the SEA.JAR done and the do the Windows Storage Manager as the system runs.

It appears to me to that it drops the second connection too soon after the first one is put back online. We always close system down. With our system it takes about 2 hours to do all three software updates Crispin Hugo Systems Programmer, Macro 4 <http://www.macro4.com/> ____________________
