Maintenance and Service Guide
Hot-Pluggable Hard Drives
Hot-Pluggable hard drives used in combination with the Compaq Smart SCSI Array Controller
can be replaced while the power is still on.
NOTE:
It is not necessary to set the SCSI ID jumpers on a Compaq replacement Hot-
Pluggable hard drive.
The SCSI ID is set automatically by the backplane board and the
Hot-Pluggable tray when the drive is installed.
CAUTION:
Before removing any Hot-Pluggable hard drive, read the guidelines listed in
the following section.
Important Guidelines About Replacing
Hot-Pluggable Hard Drives
When a drive configured for fault tolerance is replaced, the replacement drive will
automatically begin being restored when it is installed.
When a drive is in the process of being
restored, the
On-line
LED will flash green.
The LED will continue to flash until the drive is
completely restored.
Figure 2-8.
Hot-Pluggable Hard Drive LED Indicators
When replacing Hot-Pluggable hard drives, these guidelines must be followed:
n
Never remove more than one drive at a time.
When a drive is replaced, the controller uses
data from the other drives in the array to reconstruct data on the replacement drive.
If more
than one drive is removed, a complete data set is not available to reconstruct data on the
replacement drive(s).
n
Never remove a working drive when another drive has failed.
Drives that have been
failed by the controller are indicated by the amber
Drive
Failure
LED on the drive tray.
Permanent data loss will occur if a working drive is removed when replacing a failed drive.
