Hello Ayman,
We tried to make the IPMI plug-ins as general purpose as possible, but
sometimes a bit of modification is required to make them play well with
specific hardware.
To check if the daemon is receiving and processing the IMPI events for
hot swap as Lars suggested, you can add the following parameters to
the libipmidirect handler stanza in your openhpi.conf file:
logflags = "file" # "" means logging off; also use "file stdout"
logfile = "ipmidirect" # log file name prefix; ${logfile}.log
logfile_max = "10000" # maximum log file size in kilobytes
This will create a ipmidirect.log file that could be used to see what is
really going on.

This (your #5) appears to be a defect in the daemon. It is checking the
resource's ResourceCapabilities flag, and if
SAHPI_CAPABILITY_MANAGED_HOTSWAP is not set, it will always return
SA_ERR_HPI_CAPABILITY. According to the B.03.01 Specification, it should
instead be checking that SAHPI_CAPABILITY_FRU is set. Looks like this
was a change in behavior between the B.02.01 and B.03.01 HPI
Specifications.
I have submitted bug #2948127 for this.
