We recovered 2 web servers, and NFS server, and an admin server in Dec 2003, and only difference is that we run under VM in production and recovered this way. The only heads up I would mention is that we used DFDSS full volume dumps taken from a z/OS system (sharing DASD for just that reason, as we don't gen the tapes on VM), and ran into an issue restoring them at Sungard where we had to specify CPVOL as format on the z/OS restores in order for the floor VM system to recogize the volumes. Not sure how FDR will address this if applicable....... We seem to like the flexability of VM guests vs. LPAR, and with that the MDISK capability arguably offers some additional flexability/advantages (ie. disk snapshots at the CMS level using SDK storage arrays emulating 3390-9's). Good luck testing....... :-)

I did exactly that last October. Our Contract with SunGard expired, and we have since changed vendors, but I can honestly say I was the FIRST sungard customer to recover Linux.
Ours was native in an LPAR, and I had them create a VM directory that had all the devices I needed mapped to the address that z/IPL expected, as well as the OSA. So on that note, you are 100% on track. I used DFDSS CDL copies, as we don't have FDR, but I see no reason as to why this shouldn't work.
I was able to IPL the system in that guest, and then using a PC at the Sungard facility, I was able to aim a web browser at the Linux hosted web server.

Please respond to Linux on 390 Port <[EMAIL PROTECTED] IST.EDU>
We have SuSE Linux SLES8 SP03 running in a native LPAR. In a couple of weeks we will be going to Sungard for Contingency Testing. Normally we recover our z/OS system under VM as a guest. We wish to recover our Linux system as a VM guest as well. Under the VM mapping, I made sure that the UCB address for the DASD and OSA match. My plan is simply to use FDR full volume restores to recover the volumes and to boot Linux. I then developed some scripts to redefine the network configs and such.
When I run z/OS under VM, the VM userid is the processor id as defined in HCD. What will the VM userid be for the Linux guest or does it matter?
Are there any gotchas when going from native LPAR to VM for Contingency Testing?
Any and all suggestions are welcomed. Thanks as always.
Peter
