Dell PowerEdge 2550 - Manual (Page 37)

Warning Messages
A warning message alerts you to a possible problem and asks you to take corrective action before the system continues a task. For example, before you
format a diskette, a message may warn you that you may lose all data on the diskette as a way to protect against inadvertently erasing or writing over the
data. These warning messages usually interrupt the procedure and require you to respond by typing y (yes) or n (no).
Diagnostics Messages
When you run a test group or subtest in the Dell Diagnostics, an error message may result. These particular error messages are not covered in this section.
Record the message on a copy of the Diagnostics Checklist (see "
Getting Help "), and then follow the instructions in that section for obtaining technical
assistance.
Alert Log Messages From the Dell OpenManage™ Server Agent
The optional Dell OpenManage Server Agent management application program generates alert messages that appear in the Simple Network Management
Protocol (SNMP) trap log file. To see the trap log, select any enterprise under the SNMP trap log icon. Alert log messages consist of information, status,
warning, and failure messages for drive, temperature, fan, and power conditions. More information about the Alert Log window and options is provided in the
Dell OpenManage Server Agent documentation found on the Dell OpenManage Server Assistant Applications CD.
SCSI Hard-Disk Drive Indicator Codes
If a redundant arrays of independent disks (RAID) controller such as the optional PowerEdge™ Expandable RAID Controller (PERC) 3/Di is installed in the
system, three light-emitting diode (LED) indicators on each of the hard-disk drive carriers provide information on the status of the SCSI hard-disk drives (see
Table 3 -3 ). The SCSI backplane firmware controls the drive online and drive failure indicators.
Figure 3-1. Hard-Disk Drive Indicators
Table 3 -3 lists the drive indicator patterns established by the SCSI backplane firmware. Different patterns are displayed as drive events occur in the system.
For example, in the event of a hard-disk drive failure, the "drive failed" pattern appears. After the drive is selected for removal, the "drive being prepared for
removal" pattern appears, followed by the "drive ready for insertion or removal" pattern. After the replacement drive is installed, the "drive being prepared for
operation" pattern appears, followed by the "drive online" pattern.

NOTE: For the full name of an abbreviation or acronym used in this table, see "Abbreviations and Acronyms."
NOTE: Warning messages are generated by either the application program or the operating system. See "Finding Software Solutions" and the
documentation that accompanied the operating system and application program for more information on warning messages.
NOTE: If you have not enabled the integrated RAID controller or installed a RAID controller card, you will see only the "drive online" and "drive bay
empty" indicator patterns.
Condition Indicator Code
Identify drive All three drive status indicators blink simultaneously.
Drive being prepared for removal The three drive status indicators flash sequentially.
