Replacing a hard disk drive during operation
If the server uses a RAID controller for redundancy, the operation
is continued by a spare device without stopping the system even if
one of the hard disk drives that configure a disk array fails.
(Downgraded operation)
NOTE: If the RAID controller is not installed, you can not
replace magnetic disks during operation. Be sure to unplug
all the power cables when replacing magnetic disks if the
RAID controller is not installed.
When the Power Console Plus (for MR518/MR520) is not
installed, even with the RAID controller installed, a faulty hard
disk drive can be replaced, but a disk array cannot be recov-
ered (rebuilt).
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 “RAID Controller's User’s Guide.”
As a RAID0 disk array is not arranged in a redundant configu-
ration, it cannot be recovered and spare disks cannot be set.
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. (Services will be provided for a
fee.)
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.
