where does the lmhostid come from?

Unread postby ratfink » Thu Jan 27, 2011 9:22 am

I know what it is, but I'm wondering what parts can be safely swapped on different machines without invalidating node locked licenses? I read somewhere that on O2s it is on the PCI riser. Right now I'm mostly wondering about the new (to me) Origin 2200 sitting in front of me. Is it on the mid plane? The MSC? Somewhere else? But it might also be useful for others to record this information for other systems all in one spot.

lmhostid is generated from the system ID which is stored in the NIC, on Origin2X00 and Onyx2 the NIC is located on the midplane under nodeboard N1, towards the bottom of the midplane.

Origin200 = NIC the MSC (system controller board, the part with the buttons on it under the 5.25" bays)

Octane = NIC on the frontplane board.

These NICs aren't network boards, they're small SEPROMs that look like lithium batteries. They can be removed and swapped if you need to replace the part they're on or want to change your serial number for another reason.

Indigo2 8-pin DIP ROM on the serial/keyboard port riser board.

Indigo: on the backplane

Personal IRIS: 8-pin DIP PROM on the board with the power and fault LEDs.

Indy: stored in the Dallas chip in a similar fashion to the Sun hostid. It is equal to the Ethernet MAC address listed on the back yellow/orange label if you need to reset it.

Onyx/CHALLENGE: The hostid/serial number is stored on the system controller in a Dallas chip. Can be reprogrammed using the PROM monitor
