Following is the method I used to switch a swap from FBA to DIAG. I did not wish to use the third party SWAPGEN EXEC.
1) update /etc/init.d/boot.swap remove mkswap command shutdown 2) update PROFILE EXEC (swaps are formatted here) change format 162 h to format 162 h (blksize 512 boot system 3) YaST DASD : Deactivate the 162 device set Diag On for the 162 device Activate the 162 device Set MODULE="dasd_fba_mod" instead of MODULE="dasd_diag_mod" in /etc/sysconfig/hardware/hwcfg-dasd-bus-ccw-0.0.0162 leave as is DASD_USE_DIAG="1" mkswap /dev/dasdd1 swapon -a lsdasd (swap device 162 should show as DIAG now, not FBA) cd /boot mkinitrd zipl -V update /etc/init.d/boot.swap add mkswap command shutdown boot system again --- On Wed, 7/29/09, Mrohs, Ray <ray.mr...@usdoj.gov> wrote: From: Mrohs, Ray <ray.mr...@usdoj.gov> Subject: Dasd_diag_mod question To: LINUX-390@VM.MARIST.EDU Date: Wednesday, July 29, 2009, 2:04 PM Hi All, We are running SLES10 SP2, and I am trying to switch our vdisk swap from fba to diag. So far I: 1) run SWAPGEN EXEC with the reuse option (vdisks are defined in the CP directory) 2) included dasd_diag_mod in the kernel configuration and ran mkinitrd (verified with lsmod) 3) set the yast DASD option to use diag for the vdisk devices (verified in /etc/sysconfig/hardware/*) 4) included the devices in fstab as swap 5) reboot /etc/fstab: /dev/dasdf1 none swap sw 0 0 /dev/dasdg1 none swap sw 0 0 /dev/dasdh1 none swap sw 0 0 Swapon -s: Filename Type Size Used Priority /dev/dasdf1 partition 123948 0 -1 /dev/dasdg1 partition 247912 0 -2 /dev/dasdh1 partition 371872 0 -3 But the disks still show up like this: 0.0.0105(FBA ) at ( 94: 20) is dasdf : active at blocksize 512, 250000 blocks, 122 MB 0.0.0106(FBA ) at ( 94: 24) is dasdg : active at blocksize 512, 500000 blocks, 244 MB 0.0.0107(FBA ) at ( 94: 28) is dasdh : active at blocksize 512, 750000 blocks, 366 MB How can I figure out what's missing? Any help is appreciated.
