In a recent posting here Rick Troth mentioned he activates the LUNs after the initial ramdisk phase to avoid having the LUN addresses built into the ramdisk. Maybe his method can be adapted to your dasd+LUN basevol/guestvol setup.

I can't run mkinitrd and zipl from the guestvol system, as it's seeing /sys and /boot as read-only. I have added the following line to /etc/sysconfig/kernel on the basevol: INITRD_MODULES="dasd_fba_mod zfcp" and have run mkinitrd and zipl on the basevol. Without this, I would not have been able to see the LUN. When we setup the DASD beyond the 202 disk on the other guests, we had a similar problem. The solution was to write a script to mount any ext[23] filesystem in /etc/fstab that wasn't already mounted or /guestvol, and put that in /etc/init.d/rc3.d between the system scripts and the application scripts. -Matt -- Matt Gourley Systems Administrator Pennsylvania State University Administrative Information Services - Infrastructure/Sysarc Rm 25 Shields Bldg., University Park, PA 16802 (814) 865-8726 [EMAIL PROTECTED] ---------------------------------------------------------------------- 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 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
