Hello All: I am wondering how everyone handles maintenance in your VM environment with your zLinux instances. We are trying to push to move some of our UNIX servers to zLinux but the argument that arises each time we apply maintenance we have to cycle VM (when we do a put2prod). In the last month we went to 5.2, DST maintenance and we found we were missing a PTF for PerfMon. This cause us to have to cycle VM and drew some concerns from our zLinux users. The struggle is that our midrange world claims to apply patches to the UNIX servers only once or twice a year and they are concern that they will have more interruption on zLinux. I hope other shops encountered this argument and I am hoping you can give me insight on combating it. Also to note we just implemented z/VM on two CEC's and plan to allow failover between the two machines. I am hoping this will resolve some issues. We are in the infant stages of implementing z/VM and z/Linux but we are trying to get it right the first time. I have searched and found all the HA doc's and Redbooks but I am looking for any input on this issue. Thanks Frank J.
