Before You Begin; Configuring Partner Firmware Update; Verifying Component Failure - Seagate RealStor 5005 Series Hardware Installation

TIP: The illustrations show IOM module replacement within the top slot (A) as you view the enclosure rear panel. To
replace an IOM in the bottom slot (B), you would first rotate the module 180º about its longitudinal axis, so that it
properly aligns with its connectors on the back of the midplane. See also

Before you begin

Removing a controller or expansion module from an operational enclosure significantly changes air flow within the
enclosure. Openings must be populated for the enclosure to cool properly. Leave modules in the enclosure until ready to
install a replacement. If replacing both controllers in a dual-controller enclosure, use the SMC to record configuration
settings before installing the new controller modules. See
(page 90) for instructions on installing an additional controller module.
CAUTION: When replacing a controller module, ensure that less than 10 seconds elapse between inserting it into a slot
and fully latching it in place. Not doing so might cause the controller to fail. If it is not latched within 10 seconds, remove
the controller module from the slot, and repeat the process.
When two controller modules are installed in the enclosure, they must be of the same model type. When replacing both
controller modules in an operational enclosure, follow these guidelines:
1. Replace one controller as described in these instructions.
2. Wait 30 minutes: this pause ensures that the controller and its ownership of disk groups has sufficient time to
stabilize. See also
3. Check the system status and event logs to verify that the system is stable.
4. Replace the partner controller as described in these instructions.

Configuring partner firmware update

In a dual-controller system in which PFU is enabled, when you update firmware on one controller, the system
automatically updates the partner controller. Disable partner firmware update only if requested by a service technician.
Use the SMC or CLI to change the PFU setting.
IMPORTANT: See the "Updating firmware" topic within the Storage Management Guide before performing a firmware
update.
NOTE: The SMC and CLI provide an option for enabling or disabling Partner Firmware Update for the partner controller as
described in the Storage Management Guide. To enable or disable the setting via the CLI, use the set advanced-settings
command, and set the partner-firmware-upgrade parameter. See the CLI Reference Guide for more information about
command parameter syntax.

Verifying component failure

Select from the following methods to verify component failure:
• Use the SMC to check the health icons/values of the system and its components to either ensure that everything is
okay, or to drill down to a problem component. The SMC uses health icons to show OK, Degraded, Fault, or Unknown
status for the system and its components. If you discover a problem component, follow the actions in its Health
Recommendations field to resolve the problem.
