Memory Troubleshooting Best Practices for HP ProLiant
Servers
Accurately troubleshooting 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 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.
This white paper covers the following topics:
•
Why Should I Troubleshoot Every Memory Problem?
