Modifying Input/Output (I/O) Configurations
Using the SYSGEN I/O Configurator
Printing the Configuration Information
You can use the OFFLINE option to send the output of the listing commands, LCLASS, LDEV,
LPATH or LVOL, to the file SYSGLIST. Using OFFLINE does not immediately generate printed
output. The information is sent to SYSGLIST until you either enter the OCLOSE command or
exit SYSGEN. Exiting SYSGEN or using OCLOSE closes SYSGLIST and prints the file.
For example, to print information about all devices with device class DISC and LP on your
system, do the following:
1. At the I/O Configurator prompt (>io) enter:
io>LCLASS (DISC,LP) DEST=OFFLINE
Or, you can enter the command this way:
io>LCLASS (DISC,LP) OFFLINE
2. To close the file SYSGLIST and print the information, enter
io>OCLOSE
Sample Configuration Data
Example 5-4 shows the kind of information you might see if you entered the LDEV
command, without additional parameters, at the I/O configurator prompt on an N-Class
system.

LVOL Lists the attributes of the specified volume, which
is one disk pack. Each volume is a member of a
volume set and contains a volume label, a label
table, and a free space map. When you enter the
LVOL command for a specific volume, you will see
the volume's LDEV number, the amount of
transient and permanent space it has, its class
status, and the volume class it belongs to.
