Chapter 8

Installing Drivers and Setting Up the Server

8.1

Installing the Driver

Install the necessary drivers and patches following the Fibre Channel card installation guide.

8.2

Setting Up the Driver Parameters

8.2.1

For AIX Configurations (Configurations other than a VIOS/VIOC Configuration)

Use the "smit" command and other commands to set the driver parameters.

If an "fscsiN" entry (where "N" is a number) corresponding to the Fibre Channel card is displayed, delete

the hdisk device (child device of the fscsiN device) temporarily using the "rmdev" command to change the

fscsiN device parameter.

The deleted hdisk device (child device of the fscsiN device) is recreated after the server is rebooted or

when the "cfgmgr" command is executed. Enter the target fscsi number for "N".

For a SAN Boot configuration, apply the change only to the database without deleting the hdisk device

and then reboot the server.

# rmdev -p fscsiN

Set the parameter as shown in the following table.
