FCSCAN — Fibre Channel Device Scan Utility

Any changes to the fibre channel topology in order to add or delete switches/hubs should be done while the
system is not running MPE/iX. After a topology change, it may be necessary to reconfigure even existing FC
devices in the system because their hardware paths may have changed. It is always recommended that after a
topology change, the System Administrator should run FCSCAN utility with “-h” option, find out the new
hardware paths for devices and make appropriate changes in SYSGEN configuration to reflect the changes.
Although online topology change is not recommended, MPE/iX does support dynamic addition or deletion of
fibre channel devices within the existing topology. This is covered in detail under the section on FCSCAN
output with “-h” option.
