Hi,

There is an excellent tutorial on the GRUB boot loader here you should work your way through the page, I believe it will answer most of your questions.

Thanks once again to you both. Will study and try to get it to work and will get back with the results.

I thought I should update this post with how it all ended.

After last time I got stuck with not being able to install the bootloader, so I settled for the time being with at least having the rpool mirrored, providing a little higher level of reliability and safety than before.

Today I dug into the problem again determined to fix it.

The problem from before was that bootadm did not want to install to slice 2.
So I detached the disk from the rpool, applied a default solaris fdisk partition using

Code:

# fdisk -B c7t1d0p0

I then checked the partition table using format on both the original rpool disk and the one I wanted to mirror with and noticed that only the original had a slice called root at 0.
So modified the slice to be called root as well, and made it span almost the entire disk.
After that I reattached it to the rpool using

Code:

# zpool attach rpool c3d0s0 c7d0s0

which worked.

After that I reread the man pages of bootadm once more and discovered that you should use the -M flag for x86.
So I installed the bootloader using

Code:

# bootadm install-bootloader -M c7d0s0

This time it went through without any complaints so I turned off the computer and switched the disk priority in BIOS so that the new disk was first and a storage disk second, to make sure that it would not switch to the original bootdrive.
After a reboot i came to the familiar GRUB menu so it worked with booting!

Shut off, went back to bios and changed the disk priority to the new disk as first and the old bootdrive as second and the storage drives after and restarted the computer and it booted once again all the way!

I know that you in a earlier reply told me to use slice 2, but since bootadm complained about that I decided to try slice 0 instead which worked. Can that cause me any trouble down the road or am I fine as long as the computer boots and zpool status is fine?

Thought I might finish by adding two resources that helped me a bit on the way.
