Hi everyone. I'm newish here...I think I may have posted once before? Hoping someone here can help me.
I recently bought myself a z800. I've got it running and have successfully installed SLES 10 to an FCP-attached RAID array. However, I'm stuck at the same point that Connor Krukosky got stuck at with his machine - I don't have Feature Code 9904 (SCSI IPL); so I can't IPL the installed OS. There's an option in the various boot menus of SLES to boot an existing install, however I can't seem to figure out if its possible to point it to an FCP WWPN & LUN, or if it can only deal with DASD or something from that menu. Does anyone have experience with using that option? If not, does anyone know how to correctly use kexec and/or chroot to jump from a recovery mode session to my real storage? It's been a couple of years since I've messed with kexec and I've only used it to switch kernels, not entire filesystems. Is that even possible? I am able to mount my FCP LUN wihtout any issues once in recovery mode (in-fact, I wrote a quick shell script and rigged the root login to do it for me). I've already NFS'd off my /boot folder and zipl.conf to my file server (I've been IPL'ing via FTP); so I can copy them around from any other machine if needed. I also have a StorageTek 9840A ESCON tape drive defined in my IOCDS, which I should be able to read/write from within recovery mode. If someone knows what files and in what order to write them to tape, I believe I can IPL from that and use directives in the parmfile file to point to the FCP WWPN & LUN as the root file system? Clarification on that concept in-general would be good for anyone who's done it. Thanks in advance! p.s. - if anyone is interested in seeing my machine, I'm making a YouTube video series on it. The playlist is here: https://www.youtube.com/playlist?list=PLIWXRqvZs2Xf-VHIP7P80CDhGNcvwbS5T .... please do note that I do use profanity. In videos going forward I will be editing that out; so sorry about that on the older ones!
