First, before anything else, backup your data and make sure it is recoverable in a usable way.
Two tested copies at least.

Looking at this part ....
Code:
#  lspv -l hdisk1
hdisk1:
LV NAME               LPs     PPs     DISTRIBUTION          MOUNT POINT
clodba                719     719     40..223..222..223..11 N/A
# lspv -l hdisk2
hdisk2:
LV NAME               LPs     PPs     DISTRIBUTION          MOUNT POINT
clodba                720     721     00..144..223..223..131 N/A

.... suggests the logical volume is mirrored (as suggested) but you must have (at least) one LP that map to PPs that are both on hdisk2. That's a bit of a problem to the point that it's probably not worth mirroring. Lose hdisk2 and you lose logical volume integrity, the filesystem and data. It may be recoverable as far as the filesystem goes, but the data loss is unpredictable.

You may be able to turn on relocation with a chlv or a chvg -b ....command and force the re-sync. What does the full output of lslv -m clodba give you? Sadly it will be quite long given the number of LPs. You will probably see that copy 1 is entirely on hdisk1 except for one PP. You might manage to force the removal of the PPs from hdisk1 with rmlvcopy clodba 1 hdisk1 and if that works, you will have hdisk1 empty (check lspv -l hdisk1) and hdisk2 should be reduced to just 720 PPs in use.

For the future I would consider setting the volume group mirror pool strictness (is that the -M flag?) to force PPs for each LP to be on separate PVs and even to keep LV copies from being mixed across volumes. Personally, I'm more anorak than that and force the creation/extention to use the PPs I set, but that's just me.


Does that help?

vxdestroy_lvmroot

vxdestroy_lvmroot(1M)													     vxdestroy_lvmroot(1M)

NAME

       vxdestroy_lvmroot - remove LVM root disk and associated LVM volume group

SYNOPSIS

       vxdestroy_lvmroot [-v] [-b] lvm_root_disk

DESCRIPTION

       The  vxdestroy_lvmroot  command	tears  down  and removes the LVM volume group associated with the specified physical disk. This is done by
       removing the volumes in the volume group and then removing the volume group.

OPTIONS

       -b	 Invokes the setboot command to change the primary boot disk to the VxVM root disk from which the system was booted (if  the  pri-
		 mary  boot  disk is not already set to this disk).  The alternate boot device remains unchanged.  If the -v option is also speci-
		 fied, the settings of the primary and alternate boot devices are displayed.

       -v	 Outputs verbose messages including a timestamp that indicates major operations being performed.

ARGUMENTS

       lvm_root_disk
	    Specifies the device name of the LVM root disk that is to be destroyed, along with its entire volume group.

EXAMPLES

       This example shows the vxdestroy_lvmroot command invoked in its simpliest form:

       /etc/vx/bin/vxdestroy_lvmroot c5t1d0

       # /etc/vx/bin/vxdestroy_lvmroot -v -b c3t0d0
