Try excluding the FBA driver from the initrd.  The order in which they get
loaded will determine which driver picks up the DIAG disks.

Subject: VDISK swap on SLES9 and the FBA vs. DIAG driver


Has anyone gotten VDISK swap spaces to use the DIAG driver on SLES-9?  I
can't seem to.

I do this:
1) Create a VDISK in my PROFILE EXEC with 'SWAPGEN 101 524288 (DIAG'
2) Install SLES9 and specify "Set DIAG ON" in the DASD Disk Management YaST
panel
3) Add dasd_diag_mod to /etc/sysctrl/kernel, run mkinitrd and zipl.

After rebooting I get 101 as a swap space and see dasd_diag_mod loaded, but
apparently it is still using the FBA driver: # lsmod | grep dasd
dasd_fba_mod           17408  2
dasd_eckd_mod          66560  4
dasd_diag_mod          17152  0
dasd_mod               79932  9 dasd_fba_mod,dasd_eckd_mod,dasd_diag_mod
# cat /proc/dasd/devices

Thanks.
