I'm no genius but..... Your machine would come to the ok> prompt with no disks in it.... OBP sits beneath the OS and is totally independant of it so the bootblk isn't a factor in getting to the ok> .... :0/
What are you using to mirror the disks SDS/SVM or VxVM?
By rights there should be no need to break the mirrors neatly.... The whole point of mirroring them is to protect against a catestrophic failure in a disk.... Which you would have created by pulling one of them.... I'd have thought both should be bootable, you need to be absolutely sure the boot paths for rootdisk & rootmirror are correct, it's easy to miss a slice or somesuch....

LEARN ABOUT ULTRIX
reboot
reboot(8) System Manager's Manual reboot(8)
Name
reboot - automatic reboot procedures
Syntax
/etc/reboot [ -n ] [ -q ]
Description
The ULTRIX system is booted by loading a kernel image, usually into memory at location zero and transferring to zero. Because the system
is not reenterable, the kernel image must be read in from disk each time the system is bootstrapped.
When the reboot of a running system is desired, is normally used. If there are no users, can be used. The command causes the disks to be
synced, and then a multiuser reboot is initiated. The system is booted and an automatic disk check is performed. If the procedure suc-
ceeds, the system is then brought up for the users.
The system will reboot itself after a power failure or after a crash, provided auto-restart is enabled on your system. A consistency check
of the file systems will be performed and, unless the check fails, the system will resume multiuser operations.
Options
-n Prevents the disks from being synced.
-q Reboots quickly and ungracefully, without shutting down running processes first.
