Accessing the HP 16500B File
System

Accessing the HP 16500B File System
This chapter shows you how to:
•Mount the file system via NFS.
•Access the file system via FTP.
This chapter assumes that the HP 16500B mainframe is physically connected to
your local area network. If it is not connected, refer to the
HP 16500L
Administrator’s and Service Guide
for information on how to connect the
system.
Control User vs. Data User
You can access the HP 16500B file system as either the control user or
a data user.
Control User
•The control user can send programming commands to the
HP 16500B.
•The control user has read and write access to the HP 16500B file
system.
•There can only be one control user at any time. If you attempt to
access the HP 16500B file system as the control user when another
control user is already accessing the HP 16500B, or when someone
is using TELNET to access the command parser SOCKET, the
access will fail.
Data User
•The data user cannot send programming commands to the
HP 16500B.
•The data user has read-only access to the HP 16500B file system,
except under the \system\disk\hard and
1-2

\system\disk\flexible directories (the HP 16500B disk
drives) where read-write access is permitted.
•Multiple data users can access the HP 16500B.
Password and File Protection
There is no password protection built into the HP 16500L. The
HP 16500B operating system files, under the subdirectory system on
the HP 16500B hard disk, are not write protected.
CAUTION Do not delete the operating system files. If the files are deleted, the
HP 16500B will not operate the next time it is re-booted. If you accidentally
delete any of these files, copy them from the flexible disks labeled "16500
Operating System" back onto the hard disk, into the directory called
\system.
Accessing the HP 16500B File System
1-3

To mount the file system via NFS
The HP 16500B must be turned ON and completely booted up before you can
mount the file system. Once power is applied to the HP 16500B and the System
Configuration menu is displayed, allow an additional 15 seconds before
attempting to mount the system.
Be sure to unmount the HP 16500B’s file system before turning the HP 16500B’s
power OFF. If you don’t do this, you may get a "stale NFS file handle" error
message the next time you try to mount. If you get this message, unmount the
file system and try mounting again.
From Computers Running the UNIX Operating System
The syntax of the mount command is typically:
mount [symbolic name|IP address]:/[control|data] /[directory
name]
The symbolic name is the host name of the HP 16500B as set up by your
system administrator. Typically, this name is found in the /etc/hosts file on
your computer or returned by a name server. It is equivalent to the
HP 16500B’s IP (Internet Protocol) address.
The control or data option specifies the type of user you want to access the
HP 16500B as.
The directory name is the name of an empty directory in your computer’s file
system to which the HP 16500B’s file system will be mounted.

Example To mount, as the control user, the HP 16500B named "16500sys" to a
directory on your computer named "/logic", enter the following command at
the UNIX command line:
mount 16500sys:/control /logic
After you have entered this command, you will be able to see the
HP 16500B’s file system under the /logic directory on your computer.
To unmount:
umount /logic

From Computers Running the MS-DOS Operating System
To use the HP 16500L in an MS-DOS environment, you need to install a program
on your PC that allows you to use NFS protocol. One example is PC-NFS by
SunSoft Inc.
To mount the HP 16500B file system from a PC running MS-DOS, you must
create a logical drive that points to the HP 16500B file system. A typical
MS-DOS command to do this would look like one of these two examples:
net use [drive name] [host name|IP address]:/[control|data]
net use [drive name] \\[host name|IP address]\[control|data]
The choice of drive name is up to you.
The host name of the HP 16500B is set up by your system administrator.
Typically, this name is found in the hosts file on your computer or returned
by a name server. It is equivalent to the HP 16500B’s IP (Internet Protocol)
address.
The control or data option specifies the type of user you want to access the
HP 16500B as.
Example To mount, as the control user, the HP 16500B whose IP address is
"15.6.254.150" to the logical drive "L:", enter the following command at the
MS-DOS prompt. In this example, the PC-NFSapplication is used.
net use L: 15.6.254.150:/control
After you have entered this command, you will be able to see the
HP 16500B’s file system under the "L:" logical drive on your computer.
To unmount:
net use L: /d

From Computers Running MS Windows
To use the HP 16500L in an MS Windows environment, you need to install a
program on your PC that allows you to use NFS protocol. One example is
PC-NFS by SunSoft Inc.
To mount the HP 16500B’s file system from a PC running MS-Windows, use
the Network Connections menu in the Disk options of File Manager.
Example To connect to the HP 16500B system from the File Manager in MS-Windows,
Version 3.1, perform the following steps:
1Open File Manager and select Disk. Then, select Network
Connections.
2In the "New Connection" section of the pop-up menu, click on the
Drive Letter selection box and select the drive name you wish to use.

3In the Path field, type the name of the server that the HP 16500B
system is mounted on, followed by the HP 16500’s name or IP
address. At the end of the path, specify which kind of connection
you would like to establish, either "control" or "data".

To access the file system via FTP
To access the HP 16500B’s file system using ftp, enter the following
command on your computer:
ftp [symbolic name|IP address]
The symbolic name is the host name of the HP 16500B as set up by your
system administrator. Typically, this name is found in the hosts file on your
computer or returned by a name server. It is equivalent to the HP 16500B’s
IP (Internet Protocol) address.
When the connection is made, you will be prompted for a login name. Enter
"control" or "data" depending on the type of user you want to access the
HP 16500B as.
If you are prompted for a password, just press the Return or Enter key.
There is no password protection built into the HP 16500L.
Example To access, using ftp, the file system of the HP 16500B named "16500sys",
enter:
ftp 16500sys
login name: control
