Can you provide more details about the system? What is the OS and what are the disk systems involved?
I would start with sar -d, this will let you know which disk is having a problem(if it is a disk, which is usually the case with heavy IOWAIT).
Based on what is stored on that disk you can probably start tracking down any applications what would access it.

vximportdg
vximportdg(1M) vximportdg(1M)
NAME
vximportdg - import a disk group into the Veritas Volume Manager configuration
SYNOPSIS
vximportdg daname new_dgname
DESCRIPTION
The vximportdg utility performs a temporary import of the disk group contained on the disk device specified by daname to the disk group
specified by new_dgname. As the persistent disk group information is not changed within the private partition of the affected disk, the
import is only valid for the duration of the bootload or until a vxdg deport is performed.
ARGUMENTS
daname Specifies the device name (disk access name) of one of the member disks of the disk group to be imported. The other members are
imported automatically.
new_dgname
Specifies the disk group to be imported.
USAGE
One reason to use the vximportdg utility is to import a second generation of the rootdg disk group so that its objects are available for
use while a system is running on a different rootdg. To prevent volumes on the second generation rootdg from having the same device minor
numbers as volumes (such as rootvol) on the active rootdg, the importation assigns temporary non-conflicting device minor numbers. If this
occurs, vximportdg outputs warning messages detailing the mapping of the minor numbers.
