So I would go and use make_recovery -A but you do have a tpae on that box?
Code:

I don't want to mirror it ... I don't want to do it FOR NOW. As I said, I'm not a Unix admin and I don't want to play with the box.

Well my friend , its not playing that we are talking about but DR...
Your OS is installed on /dev/dsk/c1t6d0, what if the disk crashes?
How will you restart your box?
As from your previous posts I can see you are on SAN, meaning if you could add some lun that you could use for the OS you would have a spare...(if it will boot from SAN...) the wisest solution for you would be to ask for a spare disk of same type as the one installed:
ioscan -funC disk|more... usually the first three are what we are after...
5 years now I havent seen a N4000 so I dont remember if they have hot swap in standard, you confirm...
If hot swap just plug it in...
Software: Dont know if you can get mirror/ux on a out of support OS (I may have it somewhere...)
So your only alternative would be disk to disk copy (once a week?) and more specially creating a bootable tape so in worst case you can boot from tape, restore in spare drive and off you go again...

A disk to disk solution offer the possibility in case of disk failure to boot on the alternate disk which being a copy of the boot disk would leave the box up again but in the situation of the time of last copy (but you do backup regularly no? and the OS doesnt change all that much except /etc/passwd and /home etc...)

disk 2 0/5/0/0.1.0 sdisk CLAIMED DEVICE HP C5447A

Ok, I understand.
So I have to buy a SEAGATE ST318404LC disk? is not possible to use on of the other disks?

Are they used?
Code:
aco:/home/vbe $ ll /dev/*vg*/group
crw-rw-rw-   1 root       sys         64 0x010000 May  4  1999 /dev/r5vg01/group
crw-rw-rw-   1 root       sys         64 0x020000 May  4  1999 /dev/r5vg02/group
crw-r-----   1 root       sys         64 0x030000 Jun 27  2002 /dev/r5vg03/group
crw-r-----   1 root       sys         64 0x000000 May  4  1999 /dev/vg00/group

What have you installed on this box?
what are the other filesystems? (bdf)

If you have other VGs (I believe maybe one) like vg01, it will be quite logical both remaing disks be attributed to this group...

root:/ ll /dev/*vg*/group
crw-r----- 1 root sys 64 0x000000 Jul 8 2004 /dev/vg00/group
crw-r--r-- 1 root sys 64 0x010000 May 27 2004 /dev/vg01/group

I don't know if "they are used" or not.
I have the company ERP system on it (Powerplay 4GL with Oracle).
Other filesystems? don't know.
Other VGs? don't know.
