Hi all,

Is it possible to turn off visibility of ide hard disk at OBP level, so
solaris cannot see it?

Why do I need it? I've decided to add a secondary ide disk to my Sun Blade
150 to install there gentoo and play around with it. It works good (starts
up from secondary master). I though it would be good to start solaris
(installed on primary master) from silo. So I have configured silo, but it
looks that solaris will not start up until I disconnect ide cable from
gentto disk! Otherwise it complaints about gentoo disk:

"corrupt label - bad geometry"

it panics and resets. Why the hell it cares for this disk? I don't want to
disconnect ide cable every time I want to boot into solaris, it is stupid. I
tought about deleting disk2 alias from OBP, but I don't know what would be
the impact on ide bus. Or maybe there is more elegant way to accomplish
this?

Which version of Solaris is this? It should not panic when confronted
with a bad label. What type of panic is it?

Especially if it complaints about non solaris disk I think.

> What type of panic is it?
Mhm... I did not notice, cause the screens flowed to fast on the monitor. I
do not have possibility to connect via console port. For sure there was a
problem with the numbers of sectors.

Solaris is expecting to find your CDROM at Secondary Master.
Make your Gentoo disk Primary Slave.

Another problem is that your Gentoo disk is most likely formatted with a
DOS type partition table. Boot from CDROM and use either Solaris format
or Linux fdisk to install a BSD style disk label, then re-slice the disk
and re-install Linux.

??? Really? I wasn't before I inserted disk for gentoo.

This is what I can try to do.

And gentoo instalation manual says: to use disk in sun hardware you must
format it with sun disk label, see

Try:

boot kadb

which will cause the system to stop in the in the kernel debugger
when it panics.

Are you up to date with patches?

I gave up - after a called SUN service I was told that in SB 150 2 IDE disks
must be exaclty the same vendor, type and size to boot solaris properly.
Otherwise it may panic

> Are you up to date with patches?
Yes, the latest recommended patch cluster is installed.
Thanks anyway.

Hmmm. I've got two SB 100's that each have a 40 GB and a 20 GB drive,
and they run fine. They have *never* paniced. There is very little
difference between the 100 and the 150.
