How do I check if the root and swap are mirrored on my HP9000 machine?
Thank you,

Looking at swapinfo choose lvol2...
lvdisplay confirms...
Sorry VBE ... I'm lost. Please explain ... by the way, I'm a .net/web developer and we don't have a HP-Ux admin.
OK.
a) Basic commands: Use the manuals (man <command>)
1) About swap: use the command swapinfo
2) About FS layout : Use bdf
3) About LVM and FS, there are many commands:
vgdisplay, vgcreate... lvdisplay lvcreate, lvextend... pvcreate etc...
For the filesystems it depends if you have OnlineJFS... (fsadm)
But you could be using VXVM so I will not insist...
b)
If you look at the output of lvdisplay for /dev/vg00/lvol2 You see this line:
Mirror copies 1
Just typing vgdisplay vg00 will tell you how many disks are in the volume group (here 2)
but having 2 disks isnt the guarantee you are mirrored, but vgdisplay -v will tell you about all the logical volumes ( each are using 2 disks?)
and lvdisplay will confirm
You could start by lvdisplay but you would have to go through all the logical volumes to be sure...
Suddenly I realized:
What OS are you familiar with?
in HPUX, you should not have a main root filesystem, the OS by default uses more than just one filesystem when you install it...
In lvm you would have vg00 ( equivalent to AIX rootvg) the volume group used for the OS
And usually you would have:
ran:/home/vbe $ bdf|grep vg00
/dev/vg00/lvol3 307200 54696 236775 19% /
/dev/vg00/lvol1 199381 79387 100055 44% /stand
/dev/vg00/lvol7 2048000 639480 1320685 33% /var
/dev/vg00/lvol8 4096000 6624 3835569 0% /var/adm/crash
/dev/vg00/lvol6 1536000 1001171 501446 67% /usr
/dev/vg00/lvol5 500000 62904 410367 13% /tmp
/dev/vg00/lvol9 2527232 1825601 657840 74% /opt
/dev/vg00/lvol4 350000 174103 165919 51% /home
But you will notice lvol2 doesnt appear => bdf doesnt show swap...
All this to say it doesnt make much sence to only mirror / in this case...
You are to mirror the whole volume group or at least all the OS.
All the same , the system backup tool IgniteUX doesnt backup only / ... (man make_tape_recovery(1M))

I think that there is no mirror on boot .... correct?
correct!
But now more tricky:
(1 bad point for HP...)
to be able to mirror you would need mirror-ux installed and it is not free if you dont have it....
What type of OS do you have?

I assume that is HP-Ux 11i on 64 bits? Why is this important?
Wow not 11i?
Type :
uname -r
model
What does it say?
root:/ uname -r
B.11.00
It is version 11 .... right?
root:/ model
9000/800/N4000-44
Meaning you have a N4000 with 440Mhz PA-RISC processor... installed in HPUX 11.00
When was end of support already?...
This is what you are missing (hpux11):
B2491BA B.11.00 MirrorDisk/UX
We didn't have any hardware support .... ever!
So I would go and use make_recovery -A but you do have a tpae on that box?

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...)

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...
