in the troubleshooting process. When a system memory problem is suspected, check one or all of these common places to find information: • HP System Management Homepage (SMH) • HP Systems Insight Manager (HP SIM) • Server Logs • DIMM Slot LEDs IMPORTANT: When a memory error is detected, the firmware - HP ProLiant CL380 | System Memory Troubleshooting Best Practices for HP ProLiant - Page 3
. Therefore, further troubleshooting is necessary to determine which specific DIMM is failing. Use the LEDs as a tool in identifying that a memory problem may exist, but do not rely solely on the status of the LEDs to determine if hardware should be replaced.

Firmware Play in Troubleshooting Memory Problems? Many product issues that result in hardware replacement, including issues in which memory problems are suspected, are preventable or correctable with a firmware update. HP recommends checking for a firmware update before sending a part back to HP - HP ProLiant CL380 | System Memory Troubleshooting Best Practices for HP ProLiant - Page 14

System Memory Troubleshooting Best Practices for HP
ProLiant Servers
Accurately troubleshooting system memory issues in ProLiant server configurations is an important process that
can help prevent unnecessary replacement of hardware components. In addition, accurate problem diagnosis
prevents customers from experiencing unnecessary downtime while waiting for hardware that may not need
to be replaced.
Following standard troubleshooting guidelines and using them each time a memory issue is
suspected helps to establish this.
HP has developed several methods for troubleshooting memory problems in ProLiant servers.
The purpose of this white paper is to assist HP customers in troubleshooting system memory problems by
successfully isolating the specific DIMMs causing the problem. This helps to prevent nonessential replacement
of unaffected DIMMs or, in some cases, entire banks of memory. In addition, effective troubleshooting can
help determine if a firmware or other software download can resolve a problem without replacing hardware.
