To Install the SunATM Software

●

Install the SunATM software as described in the Solaris Sun Hardware Platform
Guide included on the Sun Computer Systems Supplement CD-ROM.

The Solaris Sun Hardware Platform Guide contains the software package installation
instructions specific to the Solaris operating environment supported by the software.

The software from the SunATM packages will be installed in the following
directories:

■

SunATM Device Drivers and Utilities (SUNWatm) go into:

■

/kernel/mod

■

/kernel/mod/sparcv9

■

/kernel/drv

■

/etc/init.d

■

/kernel/drv/sparcv9

■

/etc/opt/SUNWconn/atm

■

/etc/rc2.d

■

/etc/opt/SUNWconn/bin

■

SunATM Runtime Support Software (SUNWatmu) goes into:

■

/opt/SUNWconn/atm

■

/opt/SUNWconn/man

.

Note –

Man pages contained in the

SUNWatmu

package will be installed in

/opt/SUNWconn/atm/man

and will have symbolic links in

/opt/SUNWconn/man

.

(To view these man pages, add the

/opt/SUNWconn/man

directory to your system’s

$MANPATH

environment variable.) Interim API examples will go into

/opt/SUNWconn/atm/examples

.

■

SunATM Interim API (

SUNWatma

) goes into:

■

/opt/SUNWconn/atm/include

■

/opt/SUNWconn/atm/lib

■

/opt/SUNWconn/include

■

/opt/SUNWconn/lib

.

Note –

The SunATM adapters are not currently supported on diskless, dataless, or

autoclient systems. The

root

and

/usr

file systems must be local for SunATM to

operate.
