I'm having some minor issues with VDISK Swap space on Redhat AS 3 (Taroon Update 2) and the dasd_diag_mod driver. It's 31bit mode, so that should work (from what I understand). I'm using SWAPGEN (V5) for format the VDISK swap space prior to Linux IPL, that's working fine. However when RHAS detects the disk it loads the FBA driver, not the diag driver. How can I get it to use the diag driver, since it supposed to better
I don't have access to a current Red Hat AS, but I do recall there was a bug in the dasd driver that called the discipline handlers in the wrong order. The trick I used there when the FBA driver picked it up:
echo set device 200 off > /proc/dasd/devices modprobe dasd_diag_mod
Upon loading, the diag driver also looks around for disks it could use, and it will enable the disk that you just removed from the fba driver. Later patches assured that the diag driver was tried first.
