Installing a Boot Block on a Mirrored Disk Drive
If the replaced disk is an OS disk, you must install a boot block on the hard drive to
make the hard drive bootable.
Note: A boot block is a portion of computer code that makes the hard drive on
which it is installed able to start itself.
Use the following instructions to install a boot block on a mirrored disk drive of the
V880 or V890 server. You should still be logged in to an xterm window as root user.
