Download Sun Blade 6000 Disk Module Administration Guide

A single disk drive failure does not cause a data failure if the disk drives are
configured as a mirrored RAID volume. When there is no hot spare assigned to the
mirror, the failed disk drive can be hot-swapped; when the new disk drive is
inserted, the contents are automatically rebuilt from the rest of the array with no
need to reconfigure the RAID parameters.
If the mirror was configured with a hot spare, the mirror is automatically rebuilt
with the hot spare.
Caution – Possible data loss: You can remove the failed disk while the mirror is
rebuilt to the hot spare, but you must not insert a new disk in its place until the
rebuilding of the mirror is completed. While data is being rebuilt, the green LED on
the rebuilding drive will blink slowly. The rebuild process can take a number of
hours for large mirrors.
The Sun Blade 6000 Disk Module disk drives can be replaced by users.
▼ To Remove a Hard Disk Drive.
1. Observe the LEDs on the faces of the disk drives and identify the defective
disk drive.
2. Execute the software commands appropriate to the software that you are using
to prepare the hard drive for removal.
Caution – Do not operate the system with empty slots. Always insert a filler into an
empty slot to reduce the possibility of module shut down.
SAS disk drives in the Sun Blade 6000 Disk Module are hot-pluggable, so you can
remove a SAS disk drive when the disk module is installed in the chassis, as well
as when it is out of the chassis. See FIGURE 5-2 and FIGURE 5-3.
Note – When you return the disk drives to their slots, you should return each disk
drive to the same slot from which it was removed. Use an adhesive note or another
method to temporarily label the disk drives when you remove them.
