Replacing an expander module
If you do not have another drive available, contact Technical Support.
5. If there is another drive that is available to configure as a hot spare, decide which drive should be
used as the RAID rebuild target. Configure this drive as a Local Hot Spare for the RAID set.
Refer to "Making a local hot spare drive" in the
Harmonic SystemManager User Guide
for instructions.
NOTE:
Before configuring a drive as a hot spare, ensure that the drive has the correct
firmware version as determined by the SystemManager and displayed on the
Upgrade
Firmware
screen. If the drive does not have the correct version, contact Technical
Support for assistance.
Once a drive is configured as a Local Hot Spare, an automatic rebuild commences on this drive.
6. On the
RAID Utilities
screen, monitor the status for the RAID set.
The status should change from
Compromised
to
Rebuilding
immediately. If it does not, start the
rebuild manually by clicking on
Start Rebuild
.
7. Reconfigure all other hot spare drives as desired.
8. Periodically monitor the rebuild until complete.
Once complete, RAID set status changes to
Normal, Attached, Viable
.
What to do next
If you replaced a failed drive with a new drive from Harmonic, use the packaging materials (carton,
cushion, and electrostatic sensitive bag) from the replacement disk drive to carefully repackage the failed
drive and return it promptly to Harmonic for analysis. Contact Technical Support for a Return Authorization
Number (RA) before shipping the drive.
Replacing an expander module
Harmonic suggests that you label the SAS cables as you remove them from the expander module. This
will ensure the cables are correctly assigned in the new module.
CAUTION:
When replacing an expander module, the entire Spectrum system must be
shut down.
1. Power down the Spectrum system.
Refer to "Powering down a Spectrum System" in the
Spectrum System Installation Guide
for complete
instructions.
2. Disconnect the SAS cable(s) from the failed expander module.
3. Loosen the thumb screw to release the expander tray handle.
4. Open the tray handle to the left, and then pull the expander module out of the slot.
