So vg01 has only one disk...
And 8 logical volumes...

But how is it connected?
Code:
raz:/home/vbe $ ioscan -funC ext_bus
Class     I  H/W Path  Driver S/W State   H/W Type     Description
=================================================================
ext_bus   0  0/0/1/0   c720 CLAIMED     INTERFACE    SCSI C896 Fast Wide Single-Ended
ext_bus   1  0/0/1/1   c720 CLAIMED     INTERFACE    SCSI C896 Ultra Wide Single-Ended
ext_bus   2  0/0/2/0   c720 CLAIMED     INTERFACE    SCSI C875 Ultra Wide Single-Ended
ext_bus   3  0/0/2/1   c720 CLAIMED     INTERFACE    SCSI C875 Ultra Wide Single-Ended
ext_bus   4  0/7/0/0   c720 CLAIMED     INTERFACE    SCSI C875 Fast Wide Differential
ext_bus   5  0/7/0/1   c720 CLAIMED     INTERFACE    SCSI C875 Fast Wide Differential

The idea is to know if you have external scsi subsystem or are you using a SAN
we are looking for what is 0/4/0 and 0/5/0...

volunroot(8)						      System Manager's Manual						      volunroot(8)

NAME
volunroot - Remove Logical Storage Manager hooks for rootable volumes SYNOPSIS
/usr/sbin/volunroot [-a | -A] OPTIONS
Specifies that all volumes on the system disk be converted back to UNIX disk partitions, not just the root and swap volumes, rootvol and swapvol. Forces removal of the private region unless it is the last one in the system. DESCRIPTION
The volunroot script can be used to restore the accessibility of the root, swap, and other file systems on the boot disk directly through disk partitions instead of through volume devices. The script also removes other changes that were made to enable booting of the system from the root volume, so that the system will boot with no dependency on the Logical Storage Manager. When used with no options, volunroot affects only the root and swap volumes, rootvol and swapvol. For volunroot to work properly, only one plex must exist for each of the affected volumes. This plex must be the one created by volrootmir or the original plex created when the root disk was encapsulated. This ensures that the underlying subdisks will have equivalent partitions defined for them on the disk. If these conditions are not met, the volunroot operation fails and none of the volumes are converted to disk partitions. The unwanted plexes can be removed using either voledit or volplex. SEE ALSO
