Using I/O Configurator Commands
The I/O configurator commands let you list, modify, add, and delete four types of objects: classes, devices,
paths, and volumes. You can also use the I/O configurator to modify addresses with the MADDRESS command.
In addition to the specific functions, shown in Table 5-1, the I/O configurator includes the commands that are
common to all SYSGEN configurators: CLEAR, EXIT, HELP, HOLD, and OCLOSE.
Viewing the Current Configuration
To get information about the current configuration, either displayed on screen or printed, using the LCLASS,
LDEV, LPATH, and LVOL commands as described in Table 5-2.
