If the server that is not active anymore has no other purpose in life, would it be appropriate to SIGNAL SHUTDOWN the guest and then tell the other side to start the peer server? I like the idea to really see it logged off; you would not be the first one to find penguins wake up in miraculous ways (this is where STONITH etc lives). > Or even better have some smart communication via IUCV so the server can > cooperate > and decide who will take over the disk. > > Can I use CP SEND something... and trigger it in SLES10 ? > Or any other response to this ? If you have ISFC links done, you could do something with the IUCV stages in CMS Pipelines to coordinate stopping and starting on the systems. | Rob ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 ---------------------------------------------------------------------- For more information on Linux on System z, visit http://wiki.linuxvm.org/
