Hi,

The problem I have is I want to restore my AIX machine. I have created a mksysb tape from my tape drive rmt0 and I changed the bootlist using this command "bootlist -m normal rmt0 hdisk0".

However, when I display the bootlist "bootlist -om normal", it shows '-' hdisk0. I googled and found this :If a device specified in the boot list is no longer present on the system, a `-' is displayed instead of a name.

I can use my tape drive to create a mksysb tape successfully and its state is available after doing a lsdev -Cc tape.

So my question is how do I resolve this? Thanks

Anyone can help pls? Because I need to restore my AIX system and it just keep giving me LED c43 which I suspect is also due to the bootlist showing rmt0 as "-". Thanks.

C43 means "Diag boot cannot be accessed", you find a complete list of boot codes in your copy of the "Maintenance Handbook" or online here. The correct name for these codes is "three-digit-code", under which you will find it in Google (i searched for "three digit code rs/6000").

IMHO you should not put the tape drive in your normal boot list. AIX maintains 3 different boot lists and "normal" means quite that - a normal boot. It is highly unlikely that you want to boot from tape under normal conditions. You can put several devices there because you might have a mirrored rootvg and you want to boot from either disk regardless of the other one being broken or not.

As i take it you have an old RS/6000 hardware box (otherwise 4.2.1 wouldn't boot at all) the following should do:

- put the key in "secure" position and power on.
- wait until the display shows "200"
- insert the tape with the mksysb
- turn the key into "Maintenance" position and press the reset button

The system should boot now from the tape into maintenance (single user, diag) mode. Follow the menus there to restore your system.

I found a document describing the process, which seems to be accurate. To be honest i can't remember too well, as it is at least 10 years since i last booted a pre-Regatta system.

Finally, a word of moderation: we do not like to see someone bumping up threads, even more so after only one day.
