All;
Goofy question: How do I enable the server to see newly added DASD addresses post install. I'm sure this is something I've overlooked. Can anyone help re-gen my clue finder?

I have added some additional DASD, and can make the kerne l see it by echoing the addresses directly to the kernel:
[EMAIL PROTECTED] boot]# echo add range=203-206 >> /proc/dasd/devices
[EMAIL PROTECTED] boot]# cat /proc/dasd/devices 0200(ECKD) at ( 94: 0) is dasda : active at blocksize: 4096, 36000 blocks, 140 MB 0201(ECKD) at ( 94: 4) is dasdb : active at blocksize: 4096, 600840 blocks, 2347 MB 0202(ECKD) at ( 94: 8) is dasdc : active at blocksize: 4096, 600840 blocks, 2347 MB 0203(ECKD) at ( 94: 12) is dasdd : active at blocksize: 4096, 600840 blocks, 2347 MB 0204(ECKD) at ( 94: 16) is dasde : active at blocksize: 4096, 600840 blocks, 2347 MB 0205(ECKD) at ( 94: 20) is dasdf : active at blocksize: 4096, 600840 blocks, 2347 MB 0206(ECKD) at ( 94: 24) is dasdg : active at blocksize: 4096, 600840 blocks, 2347 MB
But ofcourse upon reboot the devices are no longer available to the system.
I've tried adding the addresses to the modules.conf, and even to the zipl.conf (and rerun zipl) as below, to no avail.
[EMAIL PROTECTED] root]# cat /etc/modules.conf options dasd_mod dasd=200-206
[EMAIL PROTECTED] root]# cat /etc/zipl.conf [defaultboot] default=linux target=/boot/ [linux] image=/boot/vmlinuz-2.4.20-1.1931.2.179.2.1.ent ramdisk=/boot/initrd-2.4.20-1.1931.2.179.2.1.ent.img parameters="root=LABEL=/ dasd=200-206"
