Upgrading To Larger Disk?

I have just been assigned the task of upgrading to a larger disk on a e250; however, I am use to working on Linux and x86 hardware. I would be very appreciative if someone could inform me on how this procedure can be done safely.

To begin with, the e250 has a 18 Gig primary scsi disk and a 18 Gig secondary scsi disk . One partition on the primary disk is being striped using soltice disksuite. I'm guessing that I need to copy the the striped partiton data to a server with free space, then break the striped partiton. The new disk is 72 Gigs and I want a new partition scheme on it. Once I have moved the OS from the old 18 gig disk to the new 72 Gig disk. I have to mirror the new 72 Gig disk with a secondary 72 Gig disk. I have read documentation saying the disk to disk copy using ufsdump could be done in multi-user mode, but there are numerous NFS mounts from other servers. I have read of another method using ufsdump and booting from an installation cd into single-user mode. At this point, I am confused. How can I migrate to the larger disk with a new partition scheme? I can't afford to mess this up.

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.
