1. Overview
1.1 Web-based Promise Array Management Professional
Web-based Promise Array Management Professional (hereafter abbreviated for WebPAM PRO)
is a Web-based application that locally or remotely manages N8103-105 Disk Array Controller
provided by Promise.
WebPAM PRO only supports Mozilla Firefox 1.5 or later (when monitoring from the Linux
environment) and Microsoft Internet Explorer (IE) 6.0 or later (when monitoring from the
Windows environment) as its browser. After installing WebPAM PRO, the following features
become available in the system.
Creating or deleting the following logical arrays on the graphical operation screen of
the browser
– RAID0 (data striping with one or more hard disk drives)
– RAID1 (data mirroring with two hard disk drives)
– RAID5 (data striping with parity with more than two hard disk drives)
– RAID1 spanning (same as RAID10. Data mirroring and striping with four hard disk
drives)
Checking consistency among logical drives (redundancy check)
Checking media error in disks (media patrol)
Auto-recovering degraded logical drives if entered into the state (rebuild)
To manage N8103-105 remotely from the management computer, WebPAM PRO must be
installed in the machine to which N8103-105 is connected. These two computers must be set to
allow communication with each other via TCP/IP. HTTPS or SSL is used for communication via
TCP/IP in order to endure security and encrypt transfer data.

1.2 Precautions
Be sure to read the following notes and precautions before using WebPAM PRO:
It is strongly recommended to provide media patrol or redundancy check routinely for
all logical drives and HDDs to be connected. Whether the media patrol or the
redundancy check is used may be determined as follows depending on the environment
of your system.
Redundancy
check
Media patrol Environment in which your system is subject to comparatively
Environment in which your system is always subject to load.
--- Redundancy check can continue at a constant rate under
heavy system load
small load in any period including the night.
--- Media Patrol has lower priority than other tasks in the system,
so it may make little progress under heavy system load
The above action allows you to find subsequent defects (due to degradation such as
aging) in files of low access frequency and unused areas as soon as possible. In
rebuilding after replacement of a HDD due to a failure, subsequent defects may be
found in remaining HDDs. In such a case, the system cannot be recovered. Thus,
detecting subsequent defects as early as possible is extremely effective as preventive
maintenance. Periodical redundancy check or media patrol is effective to keep the
stable operation of your system. It is strongly recommended to take the action once per
week or at least once per month. For the detailed explanation and routine action, see
the description on the scheduling of the redundancy check or media patrol in this
manual. Note that a media patrol task has been scheduled to be done on AM0:00 every
Wednesday by default.
Setting for security is required when you log on to WebPAM PRO first time. See
"Appendix A First Logon."
To start WebPAM PRO, more than 255 colors must be selected in the screen setup.
A message that indicates “Unknown”may be registered in the Event Frame of
WebPAM PRO when the system is under heavy load such as the case when mutilple
background activities are running at the same time. Even in that case, all the
background activities are properly done and will successfully be finished, and the
messages will be registered in syslog. Please close WebPAM PRO and then restart it.
The “HTTP 500 Error” window may be displayed when some load is added during
operation of WebPAM PRO or, in particular, while multiple background activities are
running. In this case, refresh the screen from the Refresh tab. For the Refresh tab, see
Section 3.3.

2. Installation/Uninstallation
2.1 Operation Environment for WebPAM PRO
The following operation environment is required for the proper operation of WebPAM PRO.
- Hardware
NEC EXPRESS5800 server available for the “N8103-105 Disk Array Controller (SAS)”
- Software
RHEL AS/ES 4 Update 5 or later
ML4SP2 or later
IMPORTANT:
Only users authorized as root are permitted to install
and uninstall WebPAM PRO.
If you have used Web-based Promise Array Manager
(WebPAM, N8103-101/103 management utility), be
sure to uninstall WebPAM before installing WebPAM
PRO. You cannot use WebPAM PRO with WebPAM.
For uninstalling WebPAM, see "Web-based Promise
Array Manager User’s Guide (Linux Version)”.
2.2 Installing WebPAM PRO
1. Untar the WebPAM PRO installation module.
Ex.) As the WebPAM PRO installation module is “WPPInst-1.00.tar.gz”:
# tar -zxvf WPPInst-1.00.tar.gz
2. Execute the WebPAM PRO installation script as follows:
# ./WPPInst.sh –e
3. Check that WebPAM PRO has been successfully installed.
WPP: Installation completed. Please reboot the system.
After installation completed, restart the system.
- 3 -
2.3 Uninstalling WebPAM PRO
IMPORTANT: Follow the procedure described in this
chapter to uninstall WebPAM PRO.
NOTE: WebPAM PRO is required for managing the
RAID system. Do not uninstall WebPAM PRO unless
you have to uninstall for maintenance including the
upgrade of the utility.
1. Go to the folder that WebPAM PRO has been installed.
# cd /opt/Promise/WebPAMPRO.
2. Execute the WebPAM PRO uninstallation script as follows.
# ./WPPUninst.sh

3. Operation
This chapter describes how to start WebPAM PRO and operations on screens appearing after
starting WebPAM PRO.
3.1 Starting and Exiting WebPAM PRO
IMPORTANT:
For a specific controller, do not start more than one
web browser or more than one tab in a browser
concurrently.
You need a certificate for security when logging in for
the first time. Install the security certificate according
to Appendix A.
Opening the WebPAM PRO screen with Internet
Explorer 7 always causes [Certificate Error] to appear
at the top of Internet Explorer. However, this does not
affect proper operations of WebPAM PRO.
When using Internet Explorer 7, a certificate warning
is always displayed on the upper right of the Internet
Explorer screen. This has no effect on WebPAM Pro
operation.
The default user name and password are
"administrator" and "password," respectively. At the
first logon, enter "administrator" and "password" as
the user name and password, respectively. For
changing the administrator’s password after the logon,
see "3.4 Managing Users." The user name and
password for logon to WebPAM PRO are accounts
exclusively used for WebPAM PRO. They are
different from the user name and password used for
logon to OS.
When you start WebPAM PRO first time, messages
with the date of 1970s may be registered. This has no
effect on WebPAM PRO operation.
NOTE: Depending on the OS used, browser, and/or color
scheme, the images shown in this manual may be
different from the actual images.
