stale root partiition - AIX 5.3

Just migrated a system from 5.1 to 5.3 which went just fine until I
decided to mirror rootvg. The system is at ML2. The mirroring seemed
to go fine:
0516-622 : Warning, cannot write lv control block data.
0516-1124 mirrorvg: Quorum requirement turned off, reboot
system for this
to take effect for rootvg.
0516-1126 mirrorvg: rootvg successfully mirrored, user should
perform
bosboot of system to initialize boot records. Then, user must
modify
bootlist to include: hdisk0 hdisk1.
But wonder what that first line means... I saw that when unmirroring it
to do the upgrade then when I did the unmirrorvg:
0516-622 rmlvcopy: Warning, cannot write lv control block
data.
0516-1135 unmirrorvg: The unmirror of the volume group failed.
The volume group is still partially or fully mirrored.
But when I ran the unmirror again it went fine:
0516-1132 unmirrorvg: Quorum requirement turned on, reboot
system for this
to take effect for 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: hdisk0.
So I thought I better check it before I reboot. I did an 'lsvg -l
rootvg' and found that all of the logical volumes in rootvg were
open/stale. I then ran a 'syncvg -l rootvg' and got a series of errors
saying it couldn't syncronize each logical volume. But when I looked
again, all of the logical volumes were synchronized except / (root). I
tried 'syncvg -l hd4' but it said it couldn't synchronize and hd4 still
shows open/stale.
I can run rmlvcopy on hd4 fine. I can also run mklvcopy of hd4 onto
hdisk1 and it works but still shows as open/stale. When I 'lspv
hdisk0' there are no stale partitions but if I run 'lspv hdisk1' it
shows 88 stale partitions - which is the amount of partitions for /.
Everytime I run 'syncvg -l hd4' I also get DISK_ERR1 errors which IBM
says mean the disk is definitely going bad. But I ran a mksysb and run
TSM on the system all night and no disk errors popped up at all. I
removed the hd4 copy on hdisk1 so it would show as open/sync in case it
gets rebooted.
Problem is I can't do much with the root partition in a stale state. I
can't replace the disk and remirror it from hdisk1 because the root
mirror is apparently stale. I am wondering if this disk is really
going bad or is it something else since I only get errors when trying
to mirror hd4.
Am I screwed here or is there some way I can try to fix the root
partition so it will mirror? I saw synclvodm but not sure if that
would help. Any help is appreciated.
