Installing and Removing Hard Disk Drive (HDD) -SCSI HDD-
121
NOTE: Hard disk drives cannot be replaced while the system 
is in operation, unless a RAID controller is installed.  Be sure 
to unplug the power cable before proceeding to replacement.
By setting a spare disk (hot spare), a disk array can be auto-
matically recovered using the spare disk when a hard disk 
drive fails.
See “MegaRAID Software Guide.”
The installation and replacement of a hard disk drive requires 
special technology and knowledge.  Toshiba recommends 
that you ask your authorized MAGNIA service provider to 
replace the hard disk drive.
Especially, pay careful attention when replacing the hard disk 
drive while the system is in operation.
An error in the replacement procedure may damage the 
server or destroy and lose important programs or data.
See “Before starting operation” on page 48 before replacing a hard 
disk drive while the system is in operation, and replace it by fol-
lowing these steps:
NOTE: When no RAID controller is installed or no hard disk 
drive is replaced during system operation with the RAID con-
troller installed, confirm a faulty disk using the status indicator 
of each hard disk drive before turning off the system power, 
and turn off the power for replacement.
Remove the front panel.
