That worked fine. We varied off the paths and the chpids, swapped the
card and then varied all back on. I had 'top' running on all linux
terminal sessions. There was no disruption.
Thanks for the help.

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.
