 Linux and Solaris dual boot....two separate SCSI Disks

I'm running linux(Rhat 6.2) right now on a 18gig scsi drive and I just
got my hands on a 9gig scsi drive and I would like to install Solaris8
on it.  On the install of Solaris 8 the installer program finds both
drives.  It says would you would you like to boot the kernel from cd
ibm18, or ibm9.  When it goes into the webinstaller, the next step. It
tells me I can only format c2t0d0 for the Solaris install.

My problem is I don't want to blast away my Linux disk.  How can I
tell what c2t0d0.  I tried to mount it and look at it but it wouldn't
let me.  Is there anyway to tell?

The best way is to setup an nvalias from the eeprom for linux

nvalias linux {disk device slice}

so you can "boot linux" and it will point to that slice instead of the
"disk" alias you alreay have from the solaris install.

to recocgnize the drives run from lunix the command df it will tell you
the name size and path of your partitions. from that you can figure out
who's c2t0d0.

now when I think about it, I think linux use another convention hd for ide
and sd for scsi. and letter for the order.
so the first scsi will be sca the 2nd scb and so on
on my machine I get
/dev/hdc5            /            you can see my HD is on the secondary
/dev/hdc10         /home
/dev/hdc1         /mnt/win_c        you can see I use two partition for
/dev/hdc6         /mnt/win_d
/dev/hdc9         /usr
/dev/hdc8        /opt

for solaris
I get
/                  (/dev/dsk/c0d0s0   ):  143848 blocks    44911 files
/usr               (/dev/dsk/c0d0s6   ): 1838100 blocks   342085 files
/boot              (/dev/dsk/c0d0p0:boot):   17722 blocks       -1 files
/proc              (/proc             ):       0 blocks     2906 files
/dev/fd            (fd                ):       0 blocks        0 files
/etc/mnttab        (mnttab            ):       0 blocks        0 files
/var/run           (swap              ): 1054368 blocks    33032 files
/tmp               (swap              ): 1054368 blocks    33032 files
/opt               (/dev/dsk/c0d0s5   ): 2973138 blocks   374667 files
/export/home       (/dev/dsk/c0d0s7   ):10026750 blocks   632909 files

the disk are called c#t#d#s#
c stands for controller number if you have one controller it will be c0 if
you have two it will be c0 or c1,...
t stands for the SCSI target number( scsi number) I do not have scsi drive
and therefore you do not see that in my table
d stands for device number connected to the target which in turn is
connected to the controller
s stands for the slice (partition)

in your case solaris says that it can only format the device 0 connected
to the target 0 connected to the controller 0.

under linux if you use the commend df you should be able to figure out the
drives you have by their size one being twice the size of the other one

beside this. I think that you need to boot solaris from the first HD and
your boot partition should be at the begining of the drive. I guess you
will have to repartition your HD containing linux to do that.

sorry I have to leave let me know if you need more info (I never resized a
drive under linux and cannot help ou on that)
