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.
