Since I tried working with 2.6.16 and 2.6.16.1, when I attempt to
mount my scsi disks, I get invalid disk label. Switch back to
2.6.15.x, and the problem goes away. Any ideas suggestions, I'm stuck
at this point to figure out what's wrong. Any help will be appreciated.
OK, here's what I've been able to find out about the issue
investigating it a lot further. Some reason it's saying my drives have
an improper checksum(See error message below).
I'm doing a build on my X1 to see if the issue also exists.
root:~# fdisk /dev/sda
Detected sun disklabel with wrong checksum.
Probably you'll have to set all the values,
e.g. heads, sectors, cylinders and partitions
or force a fresh label (s command in main menu)
I took my troubleshooting a little more. Issues the following commands,
then rebooted.
I cleared out the old header and bootloader with
dd if=/dev/zero of=/dev/sda count=1 bs=512
Then I ran fdisk, which gave me
"Device contains neither a valid DOS partition table, nor Sun, SGI or
OSF disklabel
Building a new sun disklabel. Changes will remain in memory only,
until you decide to write them. After that, of course, the previous
content won't be recoverable."
Then I configured the label and saved, then I got the following error
message.
Command (m for help): w
