Power-on self-test

When you turn on the Storwize V7000 system, the node canisters perform self-tests.
A series of tests is performed to check the operation of components and some of the options that have
been installed when the units are first turned on. This series of tests is called the power-on self-test
(POST).
If a critical failure is detected during the POST, the software is not loaded and the fault LED is
illuminated. To determine if there is a POST error on a canister, go to "Procedure: Understanding the
system status using the LEDs" on page 42.
When the software is loaded, additional testing takes place, which ensures that all of the required
hardware and software components are installed and functioning correctly.

Understanding the error codes

Error codes are generated for the Storwize V7000 by the system error-log analysis and system
configuration code.
Error codes help you to identify the cause of a problem, the failing field-replaceable units (FRUs), and the
service actions that might be needed to solve the problem.

Event codes

The Storwize V7000 software generates events, such as informational and configuration. An event code or
number is associated with the event and indicates the reason for the event.
Informational events provide information about the status of an operation. Informational events are
recorded in the event log, and depending on the configuration, can be notified through email, SNMP, or
syslog.
Description
An error notification is sent to indicate a problem that must be corrected as soon as
possible.
This notification indicates a serious problem with the Storwize V7000. For example, the
event that is being reported could indicate a loss of redundancy in the system, and it
is possible that another failure could result in loss of access to data. The most typical
reason that this type of notification is sent is because of a hardware failure, but some
configuration errors or fabric errors also are included in this notification type. Error
notifications can be configured to be sent as a Call Home email to the IBM Support
Center.
A warning notification is sent to indicate a problem or unexpected condition with the
Storwize V7000. Always immediately investigate this type of notification to determine
the effect that it might have on your operation, and make any necessary corrections.
A warning notification does not require any replacement parts and therefore should
not require IBM Support Center involvement. The allocation of notification type
Warning does not imply that the event is less serious than one that has notification
type Error.
An informational notification is sent to indicate that an expected event has occurred:
for example, a FlashCopy operation has completed. No remedial action is required
when these notifications are sent.
