4.
When migrating encrypted data to a new server, be sure to follow the recovery procedures in the
operating system documentation.
Server response time is slower than usual
Action: Be sure the hard drive is not full, and increase the amount of free space on the hard drive, if needed.
It is recommended that hard drives should have a minimum of 15 percent free space.
Memory problems
General memory problems are occurring
Action:
• Isolate and minimize the memory configuration. Use care when handling DIMMs ("DIMM handling
guidelines" on page 59).
o Be sure the memory meets the server requirements and is installed as required by the server. Some
servers may require that memory banks be populated fully or that all memory within a memory bank
must be the same size, type, and speed. To determine if the memory is installed properly, see the
server documentation.
o Check any server LEDs that correspond to memory slots.
o If you are unsure which DIMM has failed, test each bank of DIMMs by removing all other DIMMs.
Then, isolate the failed DIMM by switching each DIMM in a bank with a known working DIMM.
o Remove any third-party memory.
• To test the memory, run HP Insight Diagnostics (on page 48).
Server is out of memory
Action:
1. Be sure the memory is configured properly. Refer to the application documentation to determine the
memory configuration requirements.
2. Be sure no operating system errors are indicated.
3. Be sure a memory count error ("Memory count error exists" on page 81) did not occur. Refer to the
message displaying memory count during POST.
Memory count error exists
Possible Cause: The memory modules are not installed correctly.
Action:
1. Be sure the memory modules are supported by the server. See the server documentation.
2. Be sure the memory modules have been installed correctly in a supported configuration. See the server
documentation.
3. Be sure the memory modules are seated properly ("DIMM handling guidelines" on page 59).
4. Be sure no operating system errors are indicated.
5. Restart the server and check to see if the error message is still displayed.
6. Run HP Insight Diagnostics (on page 48). Then, replace failed components as indicated.
