Changes

Cause

The issue is due to a faulty IB_SSC

Solution

Replace the IB_SSC.

Unfortunately, since the LOM is down, is not possible to tell which I/O boat you have (PCI, PCI+, or PCI-X) via the 'showboards -v' output.

If Solaris host is up and running on the server, then is possible to have a look at the output for the following command:

# /usr/platform/`uname -i`/sbin/prtdiag -v

The I/O Devices section should hopefully provide some insight as to which I/O boat you have installed.

See the following docs for aid in understanding which type of IB_SCC is present:
