how to access MP when I connect to telnet?

After, I login to rx7420 server via telnet, then I don't know how I switch to login MP.

If you have any suggestion, please tell me.

Shalom,

The MP is accessed normally on its own IP address.

You may need to connect a PC via null modem cable and set it up first.

The toggle between MP mode and console mode is Ctrl-B

The MP is a separate LAN card and must be configured with a LAN address as well as getting a separate LAN cable. The MP is a separate computer and is always running even when HP-UX is shutdown. You configure the LAN address with a terminal connected to the serial console port.

SEP is correct
Highlight that Press Ctlr+B is very importance. and ^Ecf to get write permission

It was my experience to find that the MP is a lot more than just a secure console port. When upgrading the firmware to the MP failed, I found my machine would no longer boot. Luckily I had a backup of the MP settings.

What else does the MP do or hold that makes it so critical to the machine?

Just like a PC BIOS or any other 'smart' device with firmware, if an upgrade fails, you can lose the device, sometimes permanently.

It is actually a separate computer (an AMD chip) that runs all the time, even when HP-UX is halted. It has it's own memory, LAN card, serial port and probes into the CPU hardware. It is tightly integrated into the self-test and configuration of the partitions, CPUs, and boot code. You were lucky that the firmware upgrade failure did not require replacement of the entire MP board.

I was told by HP Engineering that this device was like any other device; the setting need to be backed up incase of failure. This was news to me. I've never seen that the MP settings needed to be backed up.

After years of upgrading firmware for everything from computers to routers to firewalls to wristwatches to tape drives to SAN switches, etc, you can safely assume that the download will destroy everything. If it doesn't, consider yourself lucky. If it fails - and you don't have a backup - well...
