Well, I think I should be able to boot off the mirror disk without removing the primary disk, after all, I can do that with Windows XP, which is the 3rd disk in the system.
But I did try that anyway and got the dreaded Error 22 for the thousand and one time.
I think this looks better:
# eeprom altbootpath=/pci@0,0/pci10de,376@a/pci1000,3150@0/sd@1,0:a
#: eeprom | grep -i bootpath
bootpath=/pci@0,0/pci10de,376@a/pci1000,3150@0/sd@0,0:a
altbootpath=/pci@0,0/pci10de,376@a/pci1000,3150@0/sd@1,0:a
BTW, found this line for x86, doesn't work either, neither file exists on my system:
# installboot /usr/platform/i86pc/lib/fs/ufs/pboot /usr/platform/i86pc/lib/fs/ufs/bootblk /dev/rdsk/${MIR_DISK}s2
#: ll /usr/platform/i86pc/lib/fs/ufs/pboot /usr/platform/i86pc/lib/fs/ufs/bootblk
/usr/platform/i86pc/lib/fs/ufs/pboot: No such file or directory
/usr/platform/i86pc/lib/fs/ufs/bootblk: No such file or directory
Update:
I was able to boot off the mirror disk, which was specified in the /grub/boot/menu.lst file.
Now question, just to be completely sure, how do I know which disk I booted off? Is there anything in the system logs that says "I booted off MIRROR disk and not primary"?
I did yank out the primary disk, tried to boot off mirror and went back to the Error 22 above.
How do I validate that the mirror disk is bootable? Can I swap primary and mirror disks and just let it boot?

lufslist
lufslist(1M) lufslist(1M)
NAME
lufslist - list configuration of a boot environment
SYNOPSIS
/usr/sbin/lufslist [-l error_log] [-o outfile] BE_name [-X]
DESCRIPTION
The lufslist command is part of a suite of commands that make up the Live Upgrade feature of the Solaris operating environment. See
live_upgrade(5) for a description of the Live Upgrade feature.
The lufslist command lists the configuration of a boot environment (BE). The output contains the disk slice (file system), file system
type, and file system size for each BE mount point.
The following is an example of lufslist output.
# lufslist BE_name
Filesystem fstype size(Mb) Mounted on
------------------------------------------------------------------
/dev/dsk/c0t0d0s1 swap 512.11 -
/dev/dsk/c0t4d0s3 ufs 3738.29 /
/dev/dsk/c0t4d0s4 ufs 510.24 /opt
File system type can be ufs, swap, or vxfs, for a Veritas file system. Under the Filesystem heading can be a disk slice or a logical
device, such as a disk metadevice used by volume management software.
The lufslist command requires root privileges.
OPTIONS
The lufslist command has the following options:
-l error_log
Error and status messages are sent to error_log, in addition to where they are sent in your current environment.
-o outfile
All command output is sent to outfile, in addition to where it is sent in your current environment.
-X
Enable XML output. Characteristics of XML are defined in DTD, in /usr/share/lib/xml/dtd/lu_cli.dtd.<num>, where <num> is the version
number of the DTD file.
OPERANDS
BE_name
Name of the BE for which file systems are to be reported. You cannot specify a BE that is involved in another Live Upgrade operation.
EXIT STATUS
The following exit values are returned:
0 Successful completion.
>0 An error occurred.
FILES
/etc/lutab
list of BEs on the system
/usr/share/lib/xml/dtd/lu_cli.dtd.<num>
