Assumptions This guide is for the person who installs, administers, and troubleshoots servers. HP assumes you are qualified in the servicing of computer equipment and trained in recognizing hazards in products with hazardous energy levels. Preparing for Changes Most problems occur when something - HP ProLiant DL170e | Error Prevention Guide - Page 5
can easily determine whether version updates are available for server BIOS, drivers, and agents. Server Design Design the server setup to minimize the impact of downtime. For example, on enterprise class servers, high availability features such as Hot-Pluggable RAID memory functionality and Hot-Plug - HP ProLiant DL170e | Error Prevention Guide - Page 6
a plan of action before the server fails, planning for failures of different hardware parts. • Check hard disk space periodically. It is recommended that hard drives have a minimum of 15 percent free space. • Scan for viruses weekly. Use the latest virus-scanning utilities available to be sure that - HP ProLiant DL170e | Error Prevention Guide - Page 7
SCSI controllers, hot-pluggable redundant power supplies, hot-pluggable fans, hot-pluggable drives, SCSI cables, network adapters, Processor Power Modules (PPMs), and perhaps even complete I/O, media, processor, and memory modules, if the server is modular. • Restock spare parts as they are used - HP ProLiant DL170e | Error Prevention Guide - Page 8
for dust on external server parts, such as fans. • Check the server after power disruptions due to acts of nature. Refer to the "Recognizing Power Problems Caused by Acts of Nature" section in this guide. Recognizing Power Problems Caused by Acts of Nature Some power problems are caused by acts - HP ProLiant DL170e | Error Prevention Guide - Page 9
on the specific power capabilities of the server, refer to the server documentation. To obtain the most accurate power capacity and assessment of power margin, use the power calculator provided on the ActiveAnswers website at http://activeanswers.compaq.com/aaconfigurator 10 Error Prevention Guide - HP ProLiant DL170e | Error Prevention Guide - Page 10
supply IMPORTANT: The power redundancy described in this section is not the same as protection provided by a UPS. In the event of a catastrophic power failure affecting each power cord providing power to the server, the server loses power and shuts down. To provide complete power protection, HP - HP ProLiant DL170e | Error Prevention Guide - Page 11
power to layers, reducing the life expectancy of the device parts being removed or replaced. Preventing Tape Drive Errors HP StorageWorks Library and Tape Tools Use HP StorageWorks Library and Tape Tools (L&TT) to update tape drive firmware, as well as manage and diagnose problems with the tape drive - HP ProLiant DL170e | Error Prevention Guide - Page 12
, HP recommends you schedule a routine cleaning every 100 hours of use to keep the tape drive in good working order. The drive also needs cleaning when the drive Status LED displays long flashes with short pauses. Refer to the device documentation for more information. Error Prevention Guide 13
