Offline Diagnostics
NOTE:
Connect a keyboard, mouse and monitor before you perform the
following procedure.
Offline diagnostics requires your solution to be offline, which means out of
production and not serving data. This is generally helpful to troubleshoot
low-level hardware issues.
It uses the following Dell native tools:
• MP Memory
• Dell Diagnostics
MP Memory
MP Memory is a Dell-developed, MS DOS-based memory test tool. This tool
is efficient for large (greater than 4 GB) memory configurations. The tool
supports single-processor or multiprocessor configurations, as well as
processors using the Intel Hyper-Threading Technology.
MP Memory operates only on Dell PowerVault servers that are Intel
processor-based. This tool complements Dell 32-Bit Diagnostics tests and
helps provide complete, comprehensive diagnostics on the controller in a
pre-operating system environment.
Dell Diagnostics
Unlike many diagnostic programs, the Dell Diagnostics helps you check your
computer's hardware without any additional equipment and without
destroying any data. If you find a problem you cannot solve by yourself, the
diagnostic tests can provide you with important information you will need
when talking to Dell service and support personnel.
CAUTION:
Use the Dell Diagnostics only to test Dell systems. Using this program
with other systems may cause incorrect system responses or error messages.
To run Dell diagnostics:
1 Insert the Dell PowerVault NX3500 Resource media into the controller's
DVD drive and reboot the controller.
The controller boots to the DVD.
