NAS e7000 v2 Maintenance and Service Guide
Do not replace multiple degraded drives at the same time, since the fault tolerance can be
compromised. 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 or drives,
and permanent data loss can occur.
Caution: Do not turn off any external unit when the server containing. A Smart Array
controller is powered up. Also, do not power up the server before powering up the drive
enclosure. If these ordering rules are not followed, the Smart Array controller may mark the
drives in this enclosure as failed, resulting in permanent data loss.
Caution: Remove or replace a hard drive only when the drive failure LED is amber. Data
loss can occur if a drive is removed when the drive online LED is green. Refer to "Hot-Plug
SCSI Hard Drive LEDs" in Chapter 4 for more information.
Caution: Remove or replace only one hard drive at a time. The controller relies on other
drives to reconstruct data on the replaced drive. Drive reconstruction is active when the
drive online LED is flashing green.
