5.1.3.1.1. Setting Up Remote Movers with mkhpss

The mkhpss utility may be used to copy the files needed for a remote Mover from the root

subsystem machine, to create the files which may not be copied, to install the required files on

the remote Mover machine, and to configure the inetd to run the remote Mover.

To create the necessary files, run mkhpss on the root subsystem machine. From the Root Subsystem
Machine menu, select the Create Config Bundle option. From this window, set the desired name of the
config file bundle and push the Create Config Bundle button.
To install the files and configure the inetd on the remote Mover machine, transfer the created config
bundle to the remote Mover machine and run mkhpss on the remote Mover machine. From the
Mover/Client Machine menu, select the Install Config Bundle item. On this window, set the appropra te
name of the bundle file and push the Install Config Bundle button.
Next, select the Mover/Client Machine menu Configuration submenu, and from this, the Securit y
Services item. From this window, select the authentication mechanism (Kerberos or Unix) using the
drop down menu of the Authentication Mechanism field. For Kerberos, complete the remaining fields
on the window and push the Configure Security Services button to set up the required files. For Unix,
there is nothing further to configure on this window.
Next, still under the Mover/Client Machine menu Configuration submenu, select the Othe r Services
item. On this window, select the checkbox for “Configure any Movers for this machine”. This checkbox
instructs mkhpss to add the proper lines for the Movers to /etc/services. It also inst ructs it, depending
upon the operating system type, either to modify the /etc/inetd.conf file or to add the appr opriate
configuration file to the /etc/xinetd.d directory to support the Movers. On thi s same window, select the
checkbox for “Set any system parameters necessary for HPSS”; this configures the local system settings
described in section 5.1.3.1.1: System Configuration Parameters on IRIX, Solaris, and Linux on page
106. At this time, there are no additional system parameters to set for AIX, so it is not actually necessary
to select this checkbox for AIX hosts.
5.1.3.1.2. Mover Configuration to Support Local File T ransfer
The Mover local file transfer (LFT) protocol allows the Movers to t ransfer data directly between a UNIX
file system and HPSS.
Caveats:
•This transfer can only occur if both the Mover and the clients have direct access to the UNIX
filesystem on which the file resides.
•If the multinode features of the Parallel FTP Client are used, the UNIX filesystem must be global
