Hi all,
I had a SAS hard drive on a Red Hat Linux 7.3 machine and was using the kernel boot line-
kernel /vmlinuz-2.4.30-ring-pae-aac-sam ro root=/dev/sda3 vga=extended panic=60
Now, I have replaced it with a SATA hard drive. When I try to boot, I get the following error messages-
VFS: Please use a correct "root=" option
Kernel Panic: Cannot mount root partition.
Rebooting in 60 secs...
During grub boot menu, I have tried editing the boot line by replacing "sda3" with "sdb3", "sdc3", "sdd3", "hda3", "hdb3", "hdc3" and "hdd3", but it didn't solve the problem.
Is there a way for me to determine the root partition name?
I'm running a Supermicro dual core box with Western Digital "Raptor" SATA 10k rpm hard drive.

Thanks,
Neelay.

One solution is to switch to your old hard drive and send the raptor to me

Other one would be upgrading to newer kernel. I do believe there isn't SATA support in your current kernel so it can't mount it. Hope this solves your problem. I would in the same time upgrade to newer distro too
