Solaris 10 on SPARC install not detecting a file system on HD?


Hi,

after tinkering around a little with Solaris 9 I am starting to understand Solaris a bit better adn have managed to create DNS primary and secondary servers using it, also SMTP mail relay server with Postfix in my secondary DNS.

I have 3 Netra T1's which are meant for me to learn Solaris better since I am a Newbee with this OS.

On one of my Netra's I had a Debian linux install on an 18GB hard drive of which now I am trying to reformat to use Solaris 10 on there to explore it's features over Solaris 9.

My problem however is this, upon install the installer can't detect any filesystem appropriate on my hard drive?

I have been over this back and forth in a previous post of which I'm finally starting to get the hang of but don't seem to be able to work this one out!

What I have done is this:

gone into shell mode of the installer after it broke out due to it saying - "hardware failiour or no filesystem detected"

used the format tool with a low level format to erase the disk.
#format>format

then used the partition command to create a partition table.

I assigned all the space to one partition on slice 0 but needed an 8MB reserved partition on slice 8, which I created in expert mode.

then I labled the disk and used the verify command which the partition information was fine and no Bad Magic Number errors!

after which I used the newfs /dev/rdsk/c0t0d0s0 to create the file system on the disk.

When I try the installer again though I get the same error??

I also used the prtvtoc /dev/rdsk/c0t0d0s0 command to verify and it comes up with the partition table as was put on the disk 0 and 8 with the relative sizes.

Am I mixing up Solaris 9 conventions here since through Google it showed the same way, also from the Sun documentation it seemed to suggest the same thing although pointing more to a graphical install but since my servers are headless I can't use that.

Although I did assume that once a readable file system and formatting scheme was applied to the disk that the Solaris partitioner would automatically detect and re-create the disk system as required for the install??

I'm lost! If anyone can be of assistance that would be great as I'm still very new to Solaris

[edit]The partition slice 0 starts from sector 34 not 0 which means that SILO may still be installed in the MBR? I did have this issue on x86's sometimes when swapping between linux and windows! Don't know about SPARC though.

Ok, well this is now an understood situation and is sorted!!

Basically the disk label was still Linux - I think 86 the numerical value from fdisk if my memory serves me well.

Anyway since the machine is a SPARC and not an x86 fdisk won't work with Solaris. So only option is to create an SMI label via expert mode in the format tool.

These two links helped me with that:

http://forums.sun.com/thread.jspa?threadID=5109840

http://www.sun.com/bigadmin/content/...at_utility.jsp

From the second link:

Quote:
Since you are in the format utility with the -e option, you have one more item to look at. Type in label, and you get the following response:

format> label
[0] SMI Label
[1] EFI Label
Specify Label type[0]:

I believe that SMI means Sun Microsystems. This is the default option, and you see this option if you enter the format utility without the -e option. The SMI option gives you your standard partition configuration of eight partitions, with partition two being the backup partition.

If you select the EFI (Extensible Firmware Interface) label, you will get another partition as shown below.
Anyway Solaris 10 is being installed as I type this so all is cool
