46 HP ProLiant DL360 Generation 4p Server (SAS Model) User Guide
In the online spare configuration, the ROM automatically configures the last
populated bank as the spare memory. If only banks A and B are populated,
bank B is the spare bank. If banks A, B, and C are populated, bank C is the spare
bank. If DIMMs in a non-spare bank exceed the limit for the single-bit
correctable errors threshold as defined by the Pre-Failure Warranty, the system
copies the memory contents of the failing bank to the spare bank. The system
then deactivates the failing bank and automatically switches over to the spare
bank.
For online spare memory support, you must observe the following guidelines:
• Dual-rank DIMMs can not be installed in any DIMM socket with online
spare memory enabled.
• The ROM must be up to date.
• DIMMs installed in a spare bank must be of equal or greater capacity than
the DIMMs installed in other banks.
For example, if bank A is populated with two 512-MB DIMMs and bank B is
populated with two 1-GB DIMMs, bank C must be populated with two 1-GB
or greater DIMMs in order for online spare memory support to function
properly.
After installing DIMMs, use RBSU to configure the system for online spare
memory support ("Configuring online spare memory" on page
67 ).
Installing DIMMs
1. Power down the server ("Powering down the server" on page 24 ).
2. Extend the server from the rack, if applicable ("Extending the server from the
rack" on page 25 ).
3. Remove the access panel ("Removing the access panel" on page 26 ).
4. If installed, remove the half-length expansion board.
5. Open the DIMM slot latches.
