If EFI Is Not Available
If it is not possible to reach the EFI (from either the main disk partition or CD), then you must use the
following tools to help solve your problem:
• Front panel LEDs (page 52)
• Management processor (MP) (page 62)
— Console messages
— System event logs (SEL)
If the Operating System Will Not Boot
If your operating system will not boot, but you are able to reach the EFI (from either the main disk partition
or CD), then use the following tools to help solve your problem:
• Using the EFI shell, check the system logs and analyze any error messages. Refer to “Error Messages and
Event Logs” on page 58. Refer to Chapter 5 of this guide (Cable Connections) and to the hp Integrity
cx2600 Operation and Maintenance Guide for information about connecting a console and using the EFI
shell. (The hp Integrity cx2600 Operation and Maintenance Guide is included on the CD provided with
your system.)
• Offline Diagnostic Environment (ODE) (page 63)
• E-Diag Tools (page 64)
If the Operating System Will Boot
If your operating system is running and you are experiencing problems, use the following tools to help solve
your problem.
• Beep Codes (page 50)
• LEDs (page 51)
• Error Messages and event logs (page 58)
If Intermittent Server Problems Occur
Intermittent problems that occur during installation can usually be traced to power source problems, to a
loose connector, or to some other hardware problem. If you are experiencing intermittent problems, proceed as
follows:
• Check MP logs and analyze the problem. (Determine if there is more than one symptom and if the
problem is random.) Refer to “Management Processor (MP) Event Logs” on page 62.
• Verify that the DC power source is stable and within the –40 to –72 VDC range.
• Reseat all rear panel connectors.
• Reseat all hot-swappable fans and power supplies.
• Reseat all main memory DIMMs.
• Reseat all internal connectors (cable harness and board connectors).
