Re: cpint install problem - what am I doing wrong? Ioctl: Inappropriate ioctl for device
Then you've done about all you can do from within the guest itself. If this is a frequent occurrence, then you might want to set up a lightweight healthcheck monitor, such as Hobbit, external to your guests. That should be able to give you sufficient warning that a guest is not responding to allow manual intervention that will keep it from being forced off by CP.

[snip] BTW is it enough for a guest to send the Q NAME command to keep the guest alive?

Following an earlier suggestion on this mailing list, I want to schedule a cron to issue a CP Q NAME or CP Q V STORE only to keep the session alive. Would it work? No. If the virtual machine is interrupted or placed in VM READ/CP READ due to the console going away, then your Linux-based command automation will never run -- the virtual machine is stopped waiting for that BEGIN command. The solution to your problem is to educate people to do what they need to do via SCIF (CP SEND) or other means.
