9.10.2 Operation after Baseboard Replacement
If the baseboard is replaced due to an error when the on-board SCSI array controller function is used for 
this server, the logical drive of the array controller is initialized again after replacement. This is because 
the data integrity information showing whether data was written correctly in the past is stored in the 
baseboard. As the information is lost due to replacement, the initialization is automatically executed to 
ensure the data integrity. This does not mean hard disk failure. 
For behavior of the initialization, see "Onboard SCSI RAID User’s Guide 1.4 Rebuilding/Initializing a 
Logical Drive".
9.10.3 Rebuild Operation by Automatic Recovery of HDD
When the on-board SCSI array controller function is used for this server, if the retry count against 
recoverable hard disk error exceeds the threshold, automatic rebuild function runs to check the entire 
disk. While the automatic rebuild function is running, the hard disk failure lamp blinks, and the front 
maintenance lamp comes on due to the ServerView function. 
 
A log "A manual rebuild has started on logical drive." remains in Log Information Viewer on GAM. 
During automatic rebuild, hard disks can be accessed, but the access performance is affected. The 
performance may be lowered up to 54%. After automatic rebuild is completed, the hard disk can be used 
in the redundant state. But, the hard disk should be replaced as soon as possible. 
 
If the above symptom (lamp, message on GAM) occurs although hard disk is not replaced, please 
contact the maintenance person or system administrator. 
* For automatic rebuild events, ServerView notification are not executed. However, if automatic rebuild 
fails, ServerView notification is done as hard disk failure.
9.10.4 Notes on Use of Domain Controller Function
In the case of disk array configuration with the on-board SCSI array controller in this server, if it is used 
as a domain controller for Windows Server 2003 x64 Editions, Windows Server 2003, or Windows 2000 
Server, the following warning message may be logged in the OS event log during startup.
For this server, the writing cache is always disabled, and never becomes enabled for the RAID logical 
drive configured with SCSI array controllers. However, this message indicates that the logical drive 
cache configuration is not correctly recognized. Even if this message is logged, the system operation is 
not affected, and data is not damaged.
Type: Warning
Source: Disk
Description: The driver detects a valid writing cache of 
\Device\Harddisk0\DR0. The data may be damaged.
