Discovering MAC addresses in OpenBoot PROM:
Enter OpenBoot Prom
Method 1: simple result
ok .enet-addr
0:3:ba:xx:xx:xx
Method 2: slightly more information
ok .idprom
Format/Type: ... Ethernet: 0 3 ba xx xx xx Date: ... Serial: ... Checksum: ...
Method 3: in-depth result
ok show-devs
Look through results for 'ethernet', 'network' or similar words. There will probably be multiple network devices.
ok cd /pci@1f,0/ethernet@5
ok .properties
You will receive an output of device properties, look for:
local-mac-address 00 03 ba xx xx xx
Repeat as necessary.
Thanks!
ReplyDeleteThanks for the info! I've been struggling with getting MAC address from one of my LDom guests. Apparently, the first two methods gave me the same MAC that was in the OpenBoot banner, but that didn't work with my AI server. Only the third method gave me the right answer and everything worked fine.
