HP-UX

So the array/mirror doesn't include the OS? everything is on the array/mirror BUT NOT the OS.... corrrect?

I took a look at "man arraydsp" ... I have to dig a little bit more in this.

How safe is this mirror? it's exactly the same thing that we have for PC?

Please let me know ... this is so very important for the company that I work for.

Thank you!!!

I cant help you here...
I dont have such a subsystem, I only once had to help a friend in a bank which had one a long time ago...( I deal with mostly HDS, and had some clarion in older days...)
look at this:
HP 12H
You will see why it is called autoraid... and why I believe the main concern I see is your unique boot disk...
Now since you have no HP sysadmin, dont you think its an opportunity for you to get to know bit more on HP-UX and its administration anyway it will always be a pleasure giving you help/advice and maybe one day it will be my turn asking some help about oracle issue or SAS issue...
If you need more
feel free to ask

Best regards

You are right .... I do see this as an opportunity to learn as much as possible about HP-UX.

If there is something that I can help you with please let me know, I will be glad to do it.

I plan to create a system recovery tape this Saturday using this command:
make_tape_recovery -x inc_entire=vg00

How do I use this tape in case of crash of the operating system? do you know?

Since you are on HPUX 11.00 you can use make_recovery -A (-d /dev/rmt/1m, no need if this is the default tape...) - Av if you sit next to console and want to watch the progress...

>How do I use this tape in case of crash of the operating system? do you know?

You would have to choose at boot to to boot from tape, that is at IPL type sea (search) at choose the sequential device
It will then ask interact? choose n
It will then display something like:
:tape (0/12/0/0.3.00.0.0.;0)INSTALL
...
then you have 10 seconds to interrupt the process otherwise it will reinstall the OS...
Unfortunately its a long time since last time I went through the complete process and you will have to wait till Im at home to look through my notes...

It is a good thing to test your recovery tape already to see if it boots ...
Then you may have to use it to modify filesystem size ( and reinstall after...) for you dont have OnlineJFS... but even you had it, you would need to go through using the tape for / /stand and the swap since they have to be contiguous...

I was able to find a complete description:
man make_tape_recovery

Please don't waste your time ... I have now samples and as I said a full documentation about the process. Thank you so much
