Installing the NIO CommKit Host Interface

Remove the Existing CommKit Version

If you are already connected to a CommKit network, you need to remove the

old version of the CommKit software before you install this version. If you

install this version without ﬁrst removing the old version, you may leave the

system in an unusable or inconsistent state.

The older CommKit version may be installed on HP-UX 9.x or on HP-UX

10.x. or 11.x.

Removing CommKit From HP-UX 10.x/11.x

1 On the CommKit server, log in as superuser.

2 Notify all users that the system is being shut down:

# /etc/wall

message

3 Back up any site-specific CommKit files you may have—for example, dksrvtab

(or srvtab files), dkhosts, and dkuidtab:

# tar -cvf

deviceFileName

dksrvtab dkhosts dkuidtab

...

You may also have other site-speciﬁc ﬁles that you wish to back up. This

separate backup allows you to restore the conﬁguration ﬁles easily under HP-

UX 10.x or 11.x, which has a different ﬁle system than HP-UX 9.x.

4 Stop all of the CommKit server and dkdaemon processes that are currently

running:

# dkitrc stop

5 Start the interactive swremove utility:

# /usr/sbin/swremove

6 Use the arrow keys to select the CommKit partition.

The product number, release number, and partition name vary with different

CommKit releases.

7 Select Actions > Mark For Remove from the menus to mark the CommKit

filesets for removal.
