Hi AIX-people!

Anyone familiar to mirroring rootvg on one scsi-disk and one ssa-disk??

I believe this is possible, but is it possible to boot on the ssa-disk??

Does this depend on type of ssa card or ssa disk??

Thanks!

To determine if you can boot from another drive enter the following command;

bootinfo -B hdiskX

Where X is the physical volume. Any number returned other then 1 means no, you
cannot boot from this drive.

Thanks for the command!

I have checked several RS servers with ssa card, and it looks as if it depends on
the type of ssa card:
