I got caught this weekend.
We were converting from a DS6800 to a DS8884 using metro mirror.
This is on Suse 11, pretty much maintained by yast.
When I brought up the Linux images, some failed due to "device path" not
being specified in the "fstab options". Anyway, we backed out.
Now looking at the setups, I did specify "device path" on all the non-LVM
volumes. But it looks like I took the default on all volumes that were to
be part of a LVM.
(so they specify "device id").
So, the LVM volumes look like:
ccw-IBM.13000000075850.6802.85-part1 ccw-0X0150-part1
So, when I go into yast, into Partitioner, and select a volume that is
currently in a LVM, I get:
The selected device belongs to a volume group (LVM1).
Remove it from the volume group before editing it.
OK, so is there a way of doing this update, without destroying and
rebuilding the LVM?
It may be that the LVM isn't a part of the problem.
We used up our standalone time on some other problems and when I started
getting hit with Linux not coming up and things like
"IBM.13000000075850.6802.85" flashing by, we were already past our go/no-go
time. So we took everything down and recabled the boxes. We also didn't
save any documentation other then what I stored in my head.
On some images, out fstab looks good, but the zipl is bad:
[ipl]
image = /boot/image
target = /boot/zipl
ramdisk = /boot/initrd,0x4000000
parameters = "root=/dev/disk/by-id/ccw-IBM.13000000075850.6801.84-part1
TERM=dumb"
I was under the impression that yast also updated the zipl.conf nowadays,
but apparently it doesn't do it automatically.
So, what is the process to get the zipl.conf updated via yast
(preferrably), by manual command, or (last resort) manually editing.
Thanks
