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?
hardware = z800
OS = RH v 7.2
[EMAIL PROTECTED] boot]# cat /proc/dasd/devices

[EMAIL PROTECTED] boot]# df

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"
Cheers;
E!
