Did you do a vgcfgrestore to reinstate the LVM configuration onto the replacement disks?
Basically it looks like your system is doing a lot of work trying to figure out what happened to its disks.
Alternatively, if you had disk mirroring on, it could be syncing up the mirrors.
You can use the vgdisplay command to list your volume group (VG) info, and lvdisplay -v to show details of each logical volume (LV).
Also, beware that if one of the replaced disks was a root mirror disk, it may not work...

vgrestore
vgrestore(1M) vgrestore(1M)
NAME
vgrestore - restore a VxVM disk group back to an LVM volume group
SYNOPSIS
/etc/vx/bin/vgrestore vg_name
DESCRIPTION
The vgrestore command restores a Logical Volume Manager (LVM) volume group that was previously converted to a VxVM disk group by the vxvm-
convert utility.
ARGUMENTS
vg_name
Specifies the name of a volume group that was converted to a VxVM disk group by the vxvmconvert utility.
EXIT CODES
vgrestore exits with one of the following values:
0 Successful completion.
>0 Failure; an error occurred.
WARNINGS
vgrestore functions only on VxVM disk groups that were converted from LVM volume groups by the vxvmconvert command.
It is a good idea to back up user data before running vgrestore, and restore it after the vgrestore completes, as vgrestore can only
restore a logical volume back to the state it was in before conversion to VxVM. If data changed on the volume while it was a VxVM volume,
the changes won't be reflected on the volume after being restored to LVM.
As part of the original conversion process, applications that once referenced the now-converted LVM volume's path names may have changed to
reference VxVM volume special device file names. Alternatively, special device file path names originally representing the now-converted
LVM volumes may have changed to symbolic links pointing to the VxVM volume path names. Be sure to undo these actions when restoring back
to LVM.
Do not use vgrestore unless you are certain that you want to restore LVM volume groups. After vgrestore this is run, the VxVM disks will
no longer exist.
EXAMPLES
To restore the LVM volume group vg03 that was converted by vxvmconvert to the VxVM disk group dg03, enter:
vgcfgrestore vg03
