2. In ServeRAID Manager select the system with Defunct (DDD) drives.
3. Right click on the system and choose “Save printable configuration and event
logs.” These logs are saved into the installation directory of ServeRAID Manager,
usually
Program Files\RAIDMAN
. The log files are saved as
RAIDX.log
where
X
is
the controller number.
4. Open the correct log for the controller with Defunct Drives and find the heading
“ServeRAID Defunct (DDD) event log.”
5. Mark hard disk drive online in order, starting from the bottom of this log.
6. Rebuild the last drive.
When the operating system is not accessible, to determine the correct order to
software replace, follow the following steps:

7. Rebuild the last drive.
Using and understanding the ServeRAID Monitor Log
The ability to read the ServeRAID log, generated by ServeRAID monitor, is a most
important part of recovering an array when one or more drives are marked Defunct
(DDD). From the ServeRAID log, you can determine in what order drives went
Defunct (DDD), and, if multiple drives are Defunct (DDD), which one is the
“inconsistent” or “out-of-synch” drive. The ServeRAID log is created by running
either ServeRAID monitor or Netfinity Manager. ServeRAID monitor is available
from the IBM web site:
http://www.ibm.com/pc/files.html
Search on “ServeRAID.”
Netfinity Manager is part of ServerGuide, which is shipped with every IBM server.
The following is an excerpt from a ServeRAID log created by ServeRAID monitor:
