Reconfiguring I/O Device Nodes
You might need to change the connection between the CMP modules and the
onboard devices described in
TABLE: Devices controlled by CMPs in 2P systems on
page 164 or TABLE: Devices controlled by CMPs in 4P systems on page 165 in one of
the following circumstances:
■ A CMP module has completely failed, you need access to a PCIe slot or device
which was attached to that CMP module, and you are unable to temporarily
replace the failed module or move an existing module over from a different slot
until the failed CMP is replaced.
■ You are upgrading from a 2P to a 4P system.

▼ Reconfigure the I/O and PCIe Fabric
The reconf.pl script reconfigures the PCIe fabric to reconnect the PCIe slots and
onboard devices to the CMP nodes as efficiently as possible. The reconf.pl script
also reconfigures the Solaris device names to match the new connections between the
CMP modules and the PCIe devices and slots. Use the reconf.pl script to reattach
each PCIe slot and onboard device to its nearest available CMP module.
To use the reconf.pl, you must have the following:
■ Solaris OS JumpStart™ server
■ Net install image
■ The reconf.pl script
Do the following:
