I would vary the paths offline, swap the card, and vary the paths online. May not be necessary but it might. No need to do anything to the linux guests, that's what VM is for.

We have a problem in our disk array. One of the ficon channel controller cards is down. Our ops wants to swap it today. This will require downing 3 channel paths out of 6 that are shared to z/VM. In the past, I have always shutdown all Linux instances and z/VM and brought it back after the card swap. If three out of the six are suddenly unavailable, would z/VM ignore them and use the only three that are available? When all the six are available when both cards are functioning, will z/VM auto-detect and use the channels? Would this all be transparent to the Linux guests? Apparently this is not an issue on the z/OS side. -- __________________ Ranga Nathan Work: 714-442-7591
