Hi. We run z10, z/VM 5.4 and SLES10 SP1. Problem: we need a 'moveable' NFS-server.
Current idea: two identical SLES10 that have a NFS server configured and have access to a dasd disk owned by a non-linux vmuserid. each server can link to the disk and starts network+nfsserver or detach disk and stop network+nfsserver, both servers have the same IPaddress. We have vmsecure and all in place to control that only one Linux server at a time can do LINK vmuser00 300 300 W. (they are in different vm systems/computerhalls) The idea is to have the linux server 'coming first' to LINK the disc in Write mode and start the network with ipaddress1 and start the NFS-server, exporting that disk. The other linux server that could not LINK to the disk in write mode, just sit there doing nothing, including does not start the network(or stops it) What I want is to send a signal from the online server to the 'offline' server to take over the disk, unmounts, offline and detach first. 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 ? Maybe we can have some smart solution for common IUCV communication in place for SP2 ? ___________________________________________ Tore Agblad Volvo Information Technology Infrastructure Mainframe Design & Development, Linux servers Dept 4352 DA1S SE-405 08, Gothenburg Sweden Telephone: +46-31-3233569 E-mail: [email protected] http://www.volvo.com/volvoit/global/en-gb/ ---------------------------------------------------------------------- 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/
