You can install DLCs separately or in a group. A DLC device manager is automatically added into the kernel and set to the "Available" state for each type of DLC installed. Installation can be verified by issuing the lslpp command as follows:
lslpp -h dlctype
where dlctype is one
of the following:
Information about an installed DLC can be displayed through Web-based System Manager, the System Management Interface Tool (SMIT), or the command line. On heavily used systems or communications ports, it might be necessary to change the DLC attributes to fine-tune the DLC performance. If receive performance is slow, and the system error log indicates that ring queue overflow is occurring between the DLC and its device handler, increase the DLC queue depth for incoming data. Finally, it is advisable to remove an installed DLC from the kernel when it is not needed for a lengthy period of time. This removal does not deinstall the DLC from the system, but allows kernel resources to be freed for other tasks until the DLC is needed again. Instructions for all of these tasks are in Managing DLC Device Drivers .
