recover hpux using make_tape_recovery

[BEN-10]

hi all ...

i backup my system once a month using make_tape_recovery.

can someone guide me on how to recover my system using my make_tape_recovery tape?

recently i boot to single mode
then i type BO P0 and it recover back my system ...
and then i left the server until it boot back normally.

is it the proper way on using it ?
is there a procedure on using make_tape_recovery ?

tq for the time ...

yes. when already completed you can found: < SERVER NAME > OK/ Failure.

and the server will be reboot again. and your restored completed.


thanks

This is the correct way of doing it... If server has finished the recovery without any errors and rebooted in multiuser mode from the disk then backup was fine and has been restored successfully.

Hi BEN-10,

Yup, that's the correct way to recover back your system to the same level as the one that has been backup with make_tape_recovery command.

Boot system from make_tape_recovery
- Interrupt system on the way up
- Search for bootable device (see ipl)
- boot P# (Sequential)
- Do not interact with IPL
- Just let the recover run as the way it is

Hope this information can help.

Cheeers,
AW.

Shalom Ben,

There is an option to intervene at the console keyboard. This is useful if you need to adjust the size of filesystems at recovery time (perhaps root was too small).

The procedure posted is good only for PA-RISC. Post back if its an itanium system. Output of the model command would be helpful if you are unsure.

Hi,

Yes it is the method to recover a PA-RISC system.

To install a system recovery image from a tape, use
the below procedure:

Step 1. Load the system recovery tape in the tape drive.
Step 2. Boot the system.
Step 3. Interrupt the boot sequence by pressing Esc.
Step 4. Select the tape drive you want to use, and then boot from it.
Step 5. Allow the installation process to complete.

On Itanium-based systems it is bit different and you need to have the latest firmware which supports the boot tape option.

Below are step:
Processor is starting autoboot
To discontinue press a key within 10 seconds.

When you see this message, press the key. You will see a menu of commands such as this.

---------------------- Main Menu --------------------------
Command Description
------- -----------
BOot [PRI|ALT|] Boot from specified path
PAth [PRI|ALT|] Display or modify a path
SEArch [Display|IPL] [] Search for boot device
COnfiguration menu Displays or sets boot values
INformation menu Displays hardware information
SERvice menu Displays service commands
Help [|] Displays help for menu or cmd
RESET Restart the system
----------
Main Menu: Enter command or menu >

Commands can be abbreviated using uppercase letters as shown. For example, the search command can be abbreviated as sea. From this menu, you can use the boot command to boot the system from a tape driver containing the Core Operating System. But before that, you need to know the device name for the tape driver drive attached to your system. The search command is used to list all bootable devices attached to the system. This includes disk drives, tape drives, and tape driver drives. The search command will show you an output like the following.

Main Menu: Enter command or menu > search
Searching for potential boot device(s)
This may take several minutes.
To discontinue search, press any key
(termination may not be immediate)

Path Number Device Path (dec) Device Type
----------- ----------------- -----------
P0 10/0/6 Random Access Media
P1 10/0/5 Random Access Media
P2 10/0/4 Random Access Media
P3 10/0/3 Random Access Media
P4 10/0/2 Random Access Media
P5 10/0/1 Random Access Media
P6 10/4/4.2 Toshiba tape driver Device
P7 10/4/4.1 Sequential Access Media
Main Menu: Enter command or menu >

On some systems, the output for the search command may be different. This command shows the path number, device path, and type of device. Path numbers are used to refer to a particular device when using commands that operate on devices. Device paths show the physical path associated with the device. The physical path of the device represents a system slot to which the device is attached. Random Access Media shows disks and tape driver drives. The Sequential Access Media type is usually used for tape drives.

Once you get this information and figure out which path number represents your tape driver drive, you can use the boot command to boot the system from the tape driver. If your tape driver is represented by P6, the boot command will be as follows:

Main Menu: Enter command or menu > Boot P7

You can also use device paths to boot the system instead of device numbers. After you issue the boot command, the system will ask you if you want to interact with the Initial System Loader (ISL). You have to answer no (N) at this point. This message is like the following.

Main Menu: Enter command or menu > Boot P7
Interact with IPL (Y or N) ?> N

Your Install and Core OS tape driver must be present in the drive at this moment. The system starts loading software from the CD and automatically goes into installation mode. A message appears on your screen similar to the following.
