Additional Integrated Mirroring Guidelines
• The hard-drive status indicator does not display any status information until after the
operating system driver initialization has occurred. To check for status information of a hard
drive prior to operating system load, use <Ctrl><M> during POST. See the
Dell PowerEdge
Expandable RAID Controller 4/IM User’s Guide for more information. During normal
operation, the status indicator is off.
NOTE:
The hard-drive activity indicator functions normally before and after the operating system
driver initialization.
NOTICE:
If you use a drive with existing data, the data will be cleared before the hard drive is added to
a mirror.
• It is recommended that any replacement drives should be blank and not previously
configured.
• It is recommended that you replace hard drives in an integrated-mirror configuration with
drives of the same capacity.
• After removing a hard drive in a hot-pluggable environment, wait at least 30 seconds prior
to installing the new hard drive.
