Hello,

Can someone give me a few pointers please.

I have a pSeries server, every time it booted it went into the Diagnostic mode. I went into the boot device management and configured iot to boot from the hdisk0 then hdisk1 followed by cd0 and rmt0, however every time the server boots up it goes back into Diag mode??

There was a warning light on the front display that reported an issue with the power supply, I fixed this as it is due to the server being powered off with out a shut down.

In desperation to work out if it was a hardware related issue as I do not understand if the diag software is on the disk or a eprom I installed YellowDog Linux, this has been running all weekend no issues and even if it did not server a great hardware test was fun to do!

I am now stuck though, I insert the AIX Cd1 and reboot the server, it boots into YDL. Pressing F1 for sms or F5 or F6 for boot options does not work. nor does 1, 5-6 numbers either.

Is the sms and boot software held on the disk? and after installing YDL over writes it?

How do I get past this issue any ideas?

And how do I stop the Diag mode keep coming up instead of the hdisk0? was there a menu option I am missing.

Grave digging a bit, but in the interest of the Zero Reply Drive (http://www.linuxquestions.org/questi...-drive-758562/) I will reply.

The answer to your problem lies in the Service Processor of the server. The service processor is telling the server to boot into diagnostics mode instead of normal mode. There are multiple ways to fix this:

• If the server is managed by a v7 HMC server you can access the ASMI web interface via the HMC's web interface.
• If the IP address is set on the service processor, you can connect a network cable to the service processor's ethernet port and point your web browser to the IP address of the service processor to access the ASMI directly
  Note: I've had problems accessing the ASMI with IE6 and TLS 1.0 enabled
• With the server in standby, connect a DB9M-DB9M serial null modem cable to the first serial port of the server and the other end to a terminal or your PC then set the serial port to 19200 8-n-1.

The username/password is admin/admin (from memory) by default.
Then just go to the startup settings and change the boot mode and you're done.
