Are your disks identical?
If strictly identical, there is an option you should try: vgreduce or split the mirror to have only one disk in vg00 then do a dd...
It should boot...
dont forget to turn off the VG_AUTO_ACTIVATE for vg01... for you will need to import the correct definition of the VG (dont know how you will do that though for SAN is not the same...)
My 2 cents:
I would go and boot the system, that will complain (duplicate address) so try to boot single user modify all that is need, ( /etc/lvmtab, fstab etc...) give a new IP and get your network team to create a VLAN so you can use it even if you are the only node in that sublan...
Once OK, activate you mirroring...
Now add vg01 (pvcreate etc...) and create all lvm as on the original.
Either copy or restore (if you backup utility will do such tasks...).
All this should be done at init level2 to be safe with no fancy unwanted overhead.

this sort of manipulation were my daily routine one time, but long, long ago...
An L3000 had at configuration/order time an option at order: you could choose a tape drive OR a DVD internal... If you wanted both you had to choose which device was external.. I had both and believe the internal tape was the best choice...

P.S.
I did also use the mirror, but had some much issues I gave up... the best of all is by far the Ignite tape, since you can start almost a fresh "install" and configure the new box immediately by giving his new name , IP etc...
Ever considered Ignite via LAN?

VALUES

DESCRIPTION

       Note: this tunable is obsoleted and has been renamed to beginning with release HP-UX 11i v3.

       This  tunable  notifies the tape driver whether it should allow access to device special files without the no-rewind-on-close option.  When
       this tunable is on the tape driver will fail any open on a tape device special file without the no-rewind-on-close option (that is, or with
       a status of

       The  tunable  allows  the  safe	sharing of tape devices in SAN tape backup solution configurations.  The disabling of device special files
       without no-rewind-on-close in a SAN tape backup solution configuration prevents the accidental sending of a rewind command  on  close  from
       HP-UX systems via standard tape commands like which would corrupt a backup in process.

   Who Is Expected to Change This Tunable?
       Anyone.

   Restrictions on Changing
       Changes to this tunable take effect immediately.

   When Should the Tunable Be Turned On?
       This tunable should be turned on if the system is going to be used in a SAN tape backup solution configuration.

   What Are the Side Effects of Turning the Tunable On?
       The  tape  driver  will	fail any open to a tape device special file that does not have the no-rewind-on-close option with a status of This
       behavior prevents the usage of any tape device special file without the no-rewind-on-close option.

   When Should the Tunable Be Turned Off?
       This tunable should be turned off if the system is not part of a SAN tape backup solution configuration or the  system  utilizes  will  not
       function unless it has access to device special files without the no-rewind-on-close option.

   What Are the Side Effects of Turning the Tunable Off?
       A rewind may be issued from this system accidentally on close possibly corrupting a backup being issued from another system on the SAN.

   What Other Tunables Should Be Changed at the Same Time?
       None.

WARNINGS

       All  HP-UX kernel tunable parameters are release specific.  This parameter may be removed or have its meaning changed in future releases of
       HP-UX.

       Installation of optional kernel software, from HP or other vendors, may cause changes to tunable  parameter  values.   After  installation,
       some  tunable  parameters may no longer be at the default or recommended values.  For information about the effects of installation on tun-
       able values, consult the documentation for the kernel software being installed.	For information about optional kernel  software  that  was
