This article describes the general process of changing or showing the characteristics of a 128-port asynchronous adapter. For a detailed discussion of configuring the 128-port asynchronous adapter and RAN, refer to "Configuring a RAN with SMIT".
Note: To make the remote asynchronous nodes detectable by the adapter, you must power-cycle the nodes affected by the configuration changes and select the Configure Devices Added After IPL option from the SMIT Devices menu.
To display the characteristics of a defined and available 128-port asynchronous adapter, enter the lsattr command at the command line, specifying the -l Name and -E flags. For example, to display the characteristics of a 128-port asynchronous adapter, enter:
lsdev -Cc adapter
Find the name of the defined adapter (for example, cxma0 ) in the displayed output from the lsdev command, and enter:
lsattr -El cxia0
lsattr -El cxma0
lsattr -El cxpa0
See the lsattr and lsdev commands for a detailed description and optional flags.
To change the characteristics of a defined and available128-port asynchronous adapter, enter the chdev command at the command line, specifying the -l Name flag. In addition, specify (multiple instances of) the -a Attribute=Value flag to change attribute values, or specify the -f File flag to retrieve attribute values from a file, or specify a combination of both.
For example, to change a defined 128-port Micro Channel asynchronous adapter named cxma0 to use an 8-wire cable on adapter line 1, enter:
chdev -l cxma0 -a line1_cabletype=8
To change a 128-port ISA adapter named cxia1 to use an 8-wire cable on adapter line 1, enter:
chdev -l cxia1 -a line1_cabletype=8
For an 128-port PCI adapter named cxpa0 to use an 8-wire cable on adapter line 1, enter:
chdev -l cxpa0 -a line1_cabletype=8
Specify the -P flag if the configuration changes should be applied only to the database. This allows the database to be changed for a 128-port asynchronous adapter that is in use, so that changes take effect the next time the system is started.
See the chdev command for a detailed description and other optional flags.
Consult the following list to find out the Attribute name for attributes that can be changed in the -a Attribute=Value flag for the characteristic to change. For example, specify -a commode_21c2=direct to change the communication mode of node 2 for the line 2 cable to direct communication transmission.
