[Linux-PowerEdge] [BUG] iDRAC6 SM-CLP UUID formatting error

[Sven Ulland]

Dell reps, would you be able to forward this bug report to the
appropriate team within Dell? I doubt it'll get through the normal
support channels.

Affected version: iDRAC6 firmware version 3.42 (Build 3) and older.

The SM-CLP shell prints the wrong system UUID, likely due to a mistake
in the endian handling in libcmpiOSBase_ComputerSystemProvider.so.1.0.
Here's how it looks in comparison to the SMBios system UUID:

SM-CLP:
-> show admin1/system1
[...]
OtherIdentifyingInfo={
   4c4c4544-04d-5a10-8058-cac04ca8474a,
   PowerEdge M610:CN<removed>00MB,
   7:1:9,
   <removed>Y4J
}

SMBios system UUID, as reported by dmidecode and similar tools:
44454c4c-4d00-105a-8058-cac04ca8474a

The first three parts are mangled, and a leading zero is missing. See
the SMBios v2.7.1 spec, section 2.7.1 for details on the UUID encoding.

On a side note, it seems the iDRAC6 smclp shell does not support the
<verb> <target> <property> syntax required by the spec:

-> show /admin1/system1 OtherIdentifyingInfo
COMMAND SYNTAX ERROR :
show /admin1/system1 OtherIdentifyingInfo
