1.2 Precautions
Be sure to read the following notes and precautions before using WebPAM PRO:
 We strongly recommend to routinely perform a media patrol or redundancy check for all the
logical drives and HDDs connected. Depending on your system environment, use either the
media patrol or the redundancy check.
Redundancy
check
Environment in which your system is always subject to load.
--- Redundancy check can continue at a constant rate under
heavy system load.
Media patrol Environment in which your system is subject to a comparatively
small load during a period of time, 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 as soon as possible any subsequent defects (due to
such degradations as aging) in files of low access frequency and unused areas.
When rebuilding after the replacement of a defective HDD, subsequent defects may be
found in the remaining HDDs, preventing the system from being recovered. This
explains why detecting subsequent defects as early as possible is extremely effective in
terms of preventive maintenance.
To ensure the stable operation for your system, we recommend to perform either
synchronization or media patrol once per week or at least once per month.
For more information, refer to the description on the scheduling of the synchronization
or media patrol in this manual. Note that a media patrol task is by default scheduled for
AM0:00 every Wednesday.
 To use the NEC ESMPRO Manager report monitoring or the express report service, the
NEC ESMPRO Agent must be installed before the installation of WebPAM PRO. Install the
ESMPRO modules supplied in the “SAS Array Management Software” CD-ROM and also
perform update of WebPAM PRO SNMP module also in that CD-ROM.
 To use WebPAM PRO with the Internet Explorer, some default settings of Internet Explorer
must be changed. Change the default settings following the instructions in "Appendix A
Preparation for Using WebPAM PRO on Internet Explorer."
 After installing WebPAM PRO, always install the Standby/Hibernation Lock following the
instructions in the Appendix C. This RAID system does not support power control features.
 To start WebPAM PRO, the display setup must be higher than 255 colors. If this is not the
case, a popup requesting more than 255 colors is displayed and MSM does not start.
 The timestamp displayed in the WebPAM PRO screen may be later than the actual
timestamp. Please see the timestamp in the OS application log when you check the event
messages.
 The message “This page contains both secure and nonsecure items. Do you want to display
the nonsecure items?” may be displayed during WebPAM PRO operation. In this case, click
OK to continue the operation.
 The “HTTP 500 Error” window may be displayed particularly while multiple background
activities are running. In this case, refresh the screen using the Refresh tab. For the Refresh
tab, see Section 3.3.
