If you have one missing disk in rootvg, and also in the boot list, you may get the following error if you do not remove it from rootvg:
# bosboot -ad /dev/hdisk3
0301-108 /usr/lib/boot/bin/mkboot_chrp: Unable to read file blocks. Return code: -1
0301-158 bosboot: mkboot failed to create bootimage.
0301-165 bosboot: WARNING! bosboot failed - do not attempt to boot device.
Now, the story behind this error, in our situation.
The hdisk0 is declared missing:
# lsvg -p rootvg
rootvg:
PV_NAME PV STATE TOTAL PPs FREE PPs FREE DISTRIBUTION
[color=red]hdisk0 missing 546 360 109..15..18..109..109[/color]
hdisk3 active 546 366 109..21..18..109..109
The command dd is confirming that the disk is unusable:
Yes, with this command you can verify the availability of a disk.
# dd if=/dev/hdisk0 of=/dev/null count=10
dd: 0511-051 The read failed.
: There is an input or output error.
0+0 records in.
0+0 records out.
List the LVs from each hdisk to make sure you have them all mirrored.
If you have partitions only on hdisk0, be sure they are lost.

As you can see above, you need to remove the sysdump device and you will have to create it on the other disk afterwards.

Now unmirror rootvg and remove hdisk0.
You can ignore the errors - the disk is unusable and it is normal:
# unmirrorvg rootvg hdisk0
0516-1246 rmlvcopy: If hd5 is the boot logical volume, please run 'chpv -c <diskname>'
as root user to clear the boot record and avoid a potential boot
off an old boot image that may reside on the disk from which this
logical volume is moved/removed.

0516-1798 lchangevg: Cannot change quorum without losing quorum.
0516-732 chvg: Unable to change volume group rootvg.
0516-1144 unmirrorvg: rootvg successfully unmirrored, user should perform
bosboot of system to reinitialize boot records. Then, user must modify
bootlist to just include: hdisk3.
