Problem using a tape recovery : HIDE_BOOT_DISK ?

Hello everybody,
I upgrade my system HP-UXi from v1 to v2.
After this upgrade (all is working pretty well), I created a boot tape and a backup of my all system (RAID 0) by the following command :
# make_tape_recovery -x inc_entire=vg00 -v -I

But now, when I test a recover from the tape, there is an error message concerning the hard drive.

On the recovery menu, the hard drive are been well detected :
Hardware Summary: System Model: 9000/800/rp3440
+---------------------+----------------+-------------------+ [ Scan Again ]
| Disks: 2 (444.1GB) | Floppies: 0 | LAN cards: 1 |
| CD/DVDs: 1 | Tapes: 1 | Memory: 4094Mb |
| Graphics Ports: 0 | IO Buses: 5 | CPUs: 2 | [ H/W Details ]
+---------------------+----------------+-------------------+

but, when I select [ install HP-UX ], I have an error message that there is no hard drive !!?? and the recovery could not process.
This is the error message :

***********************************************
* Checking configuration for consistency...
ERROR: The disk at: 0/4/1/0/4/0.0.0 (HP_LOGICAL_VOLUME) was specified to be
configured but is currently prevented from being configured by the
HIDE_BOOT_DISK option and/or the _hp_hide_other_disks config file
variable.
ERROR: The disk at: 0/4/1/0/4/0.0.1 (HP_LOGICAL_VOLUME) was specified to be
configured but is currently prevented from being configured by the
HIDE_BOOT_DISK option and/or the _hp_hide_other_disks config file
variable.

Because of the error(s) above, the user-interface must be
used to correct them... Non-interactive install canceled.
***********************************************

Before to upgrade to HP-UXiv2, I make the same process and it works good.

Have you got an idea ?
Does it means that there is a problem on the backup tape or on the properties of the disk on the v2 system ?

Thanks in advance for your help

Check this link...might be useful to you.

http://www1.itrc.hp.com/service/cki/search.do?category=c0&prevQueryString=&mode=text&searchString=UIUXKBRC00008346&searchCrit=allwords&docType=Security&docType=Patch&docType=EngineerNotes&docType=BugReports&docType=Hardware&docType=ReferenceMaterials&docType=ThirdParty&dateRange=all&search.x=14&search.y=15

as is documented in RCEN UIUXKBRC00008346, the default is to protect disks without a filesystem on them during the recovery process. This can be circumvented by either modifying the variables HIDE_BOOT_DISK and/or _HP_HIDE_OTHER_DISKS (see instl_adm(4)),or by using the "Additional" button under the "Basic" tab.
The reason that this behavior was chosen as the default is because
when Ignite encounters a disk without a filesystem on it, it cannot
determine if it is a new "empty" disk, or possibly a disk containing raw
data, such as from a database. To protect users from inadvertently destroying
valuable data, the default action is to require the user to take a positive
action to specify that the disk(s) in question are really available to be
used for a new purpose. Admittedly the majority of users would not encounter
the situation where raw data was being used in this fashion, but since the
consequences of overwriting such data is catastrophic, the design decision
was made to err on the side of safety.

Thanks Luis for your reply.
As my server is not yet in production, I all re-installed with the DVD support.
An advice was given to me on an another forum to not use update-ux to upgrade a machine.
Now, I'm trying to make a bootable tape of my system, testing a recovery and it's work very well.
