Hot-Plug Hard Drive; Before You Begin; Verifying Component Failure - HP 418800-B21 - StorageWorks Modular Smart Array 70 Storage Enclosure Maintenance And Service Manual

Hot-plug hard drive

Before you begin

CAUTION:
Before removing the failed component, make sure that you have the replacement part available.
•
Removing a component impacts the airflow and cooling ability of the device.
Do not remove more than one component or blank from the enclosure at a time. Doing so impacts
•
the airflow and cooling ability of the device. To avoid possible overheating, insert the new or
replacement component as quickly as possible. If the internal temperature exceeds acceptable limits,
the MSA70 may overheat and automatically shut down or restart.
Parts can be damaged by electrostatic discharge. Use proper anti-static protection.

Verifying component failure

Use the following methods to verify component failure:
Check the host log or run an ADU report for hard drive errors.
•
Check the hard drive status LEDs as identified in the following table:

Fault/UID LED Interpretation
(amber/blue)
The drive has failed, or a predictive failure alert has been
and blue received for this drive; it also has been selected by a
management application.
The drive is operating normally, and it has been selected by a
management application.
Amber, flashing A predictive failure alert has been received for this drive.
regularly (1 Hz)
Replace the drive as soon as possible.
Off The drive is online, but it is not currently active.
Amber, flashing Do not remove the drive. Removing a drive may terminate the
regularly (1 Hz) current operation and cause data loss.
The drive is part of an array that is undergoing capacity
expansion or a stripe size migration, but a predictive failure alert
has been received for this drive. To minimize the risk of data
loss, do not replace the drive until the expansion or migration is
complete.
Off Do not remove the drive. Removing a drive may terminate the
current operation and cause data loss.
The drive is rebuilding, or it is part of an array that is undergoing
capacity expansion or a stripe size migration.
The drive is active, but a predictive failure alert has been
regularly (1 Hz) received for this drive. Replace the drive as soon as possible.
The drive is active and it is operating normally.
Steadily amber A critical fault condition has been identified for this drive and the
controller has placed it offline. Replace the drive as soon as
possible.
Amber, flashing A predictive failure alert has been received for this drive.
regularly (1 Hz) Replace the drive as soon as possible.
