Using Linux Server Blade Utilities |
This chapter provides information on using the following utilities with Linux server blades:
Use this utility to detect memory problems on a server blade. See Performing Memory Diagnostics on a Server Blade.
Use this utility to upgrade the BIOS. See Upgrading the BIOS.
This section tells you how to use the memdiag utility to detect memory problems on a server blade.
The memdiag utility uses ECC functionality to report any errors on DIMMs installed in the server blade. If a fault is reported by memdiag, you may need to replace the faulty DIMM. It is recommended that you run memdiag on any server blade that is experiencing problems.
Note - The memdiag utility is installed on the server blade as part of the PXE boot installation process. See Chapter 4 for information on performing a PXE boot installation. |
1. Log into the blade for which you want to perform a memory test.
where n is the number of the slot containing the blade.
2. Run memdiag from the /usr/local/bin directory:
Starting Tests Starting Memory Test Testing 512M PASS Memory Test Starting ECC Test Testing 512M PASS ECC Test Ending Tests |
In this example no ECC errors were reported on the server blade.
3. Check the output for memory and ECC failures.
