The number is indeed the CPU that OBP session is running on. This can change on from "0" to any of the available CPUs in the LDom or Dynamic Domain. As why it would change from one CPU to another, may be a change in newer OBP versions that are able to take advantage of multiple CPUs or threads?
FYI, the ILOM code runs on the service processor. The OBP is loaded from the ILOM into a domains run-time environment which consists of the vCPUs and Memory allocated. So the OBP in each LDom is independent and will execute on the CPUs that are present in that domain. This is very similar to how OBP works on the dynamic system domains on the E10k, Sun Fire 3800 - 25k, and the M4000 -M9000. *-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-* Octave J.

Since no one else has posted a more authoritative reply, here's mine: I think the number is the CPU or maybe CPU/core. I don't know why it would change over time though. Maybe it's down to timing, if you changed the hardware in some way. -- This message posted from opensolaris.org _______________________________________________ sysadmin-discuss mailing list [email protected] http://mail.opensolaris.org/mailman/listinfo/sysadmin-discuss _______________________________________________ sysadmin-discuss mailing list [email protected] http://mail.opensolaris.org/mailman/listinfo/sysadmin-discuss
