The frame is p7 IH with AIX 71D Gold build, we have 316 diskless CNs and 2 SNs.
After rnetbooting, when I rebooting CNs by "rpower .. boot", some CNs ran into openfirmware, I reran rpower and it still stuck there. At last I ran rnetboot and it went up. I think it may related with the bootseq which should be set up by the postscripts : setbootfromnet.
I checked the CNs after it came up(Since it has be rpowered up, I am not sure if the output is still making sense):
Running postscript: setbootfromnet
0514-202 bootlist: Invalid device name (hf0)
But lsdev showed "Defined" of hf0, so may this confused the setbootformnet and made it fail, can you check it, Hua Zhong?
