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