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.
