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.
Parameter
init_link
num_cmd_elems
