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:
