I just had to replace an 8G drive in a B series workstation. These
machines have 2 drives in them set up using LVM and software mirroring. I
was able to et the replacement drive to remirror OK, but I recall from the
original build out of these machines, many many ears ago, that when i was
testing this I could not get the machine to boot with one of the 2 drive
removed. Turned out that both SCSI ID 5, and 6 (the 2 internal drives)
needed to have the "boot block" on them

How do I make certain that this replacement drive gets this installed?

The OS is 10.20, if that matters.

pvcreate -B I'd guess (then mkboot, then lvlnboot, etc). See the chapter about
mirroring a boot disk...
