Take Corrective Action; Table 6 Corrective Action For Fault Conditions - Seagate Exos CORVAULT Hardware Installation And Maintenance Manual

Take corrective action

After you follow the process above and isolate the fault to an area of the storage enclosure or to a particular module, use
the following chart to determine the type of corrective action you should take.

Table 6 Corrective action for fault conditions

A fault condition related to
the hardware in the main
bay
A fault condition related to
the hardware in the
auxiliary bay
the hardware in the rear
panel area
Recommended action
1. Scan the enclosure event log for specific information for the fault.
2. For system application faults, refer to
page 59.
3. If the above actions do not resolve the fault, isolate the fault to the failing
component identified in the rear panel area and follow the instructions below.
1. Inspect SAS expander modules for a fault amber LED that is on. If so, replace the
SAS expander module as soon as you have a replacement.
2. Inspect the LEDs on the main bay disk drive modules for these conditions:
Both disk drive module LEDs are off.
l
A disk drive module fault amber LED is on, not flashing.
l
3. Select one of the following actions:
If both LEDs are off, verify that the disk drive module is fully inserted, the
l
latch is fully engaged, and the storage enclosure is powered on.
If the fault LED is on, narrow the fault to the disk drive module, a
l
connection, or both.
4. Scan the enclosure event log for specific fault information and follow
recommended actions.
5. If the above actions do not resolve the fault, replace the faulty disk drive module
or cable and connector as soon as you have a replacement.
1. Inspect controller fan modules for a fault amber LED that is on. If so, replace the
controller fan module as soon as you have a replacement.
2. Inspect the LEDs on the four (4) disk drives.
3. Select one of the following actions:
If both LEDs are off, verify that the disk drive module is fully inserted, the
l
latch is fully engaged, and the storage enclosure is powered on.
If the fault LED is on, not flashing, then narrow the fault to the disk drive
l
module, a connection, or both.
4. Scan the enclosure event log for specific fault information and follow
recommended actions.
5. If the above actions do not resolve the fault, isolate the fault, and then replace
the disk drive module as soon as you have a replacement.
1. Inspect the FRUs in the rear panel for fault condition LEDs: the controller
modules (CMs), the system fan modules, and the power supply units (PSUs).
2. Scan the enclosure event log for specific fault information and follow
recommended actions.
3. Narrow the fault to a FRU, a connection, or both, then follow the recommended
actions for the related FRU.
