RE: [Panicsel-developers] hwreset -o option

[Cress, A. R <and...@in...>]

Neil,

Well, the utility should report this as an error, rather than ok.
The status was ok, but the completion code =3D 0xcc indicates that
the firmware said that the data field was invalid (the 0x05 byte,
pertaining to the -o option). =20

In the IPMI spec in Table 22-4, the 0x05 value for chassis control
says that this is a soft-shutdown via ACPI, and that it is optional.
The Langley platform firmware doesn't implement this option.

The way that ISM does an OS shutdown on this platform, is to do=20
"init 0" and set up a watchdog event for the IPMI reset with a=20
timeout that allows enough time for the shutdown to complete (about 50
sec).

I guess I could've implemented that in hwreset, but I had thought that
this=20
method would be more IPMI-generic. =20

Hmmm.  The best thing would be to use the IPMI DeviceID to determine
which method to use.  Since we know that several platforms don't=20
implement this reset option intrinsically, we could detect the platform=20
type for those and use the other method.
I'll put in that code.

Andy

Subject: [Panicsel-developers] hwreset -o option




 Hi,

 When I try to use hwreset with the -o option on a langley server
 it reports that the IPMI reset succeeded ok but in fact no
 reset occurs. I'm unclear whether the "Invalid data field" in=20
 the verbose output indicates a malformed ipmi request or a
 problem with the imb ipmi driver.

 Thanks,

  Neil
