The SAN Volume Controller error
event log contains details of error events and informational events
that have occurred on the system. You also receive log data for the
commands that have been run.
Error data
Error data consists of two types
of events:
- An error event is logged when a failure condition is detected.
An error event has an associated error code. Each error code has a
service action that must be performed as soon as possible. The service
actions are automated through the Directed Maintenance Procedures.
- An informational event is logged when a significant change of
state occurs, for instance, a FlashCopy® completes.
Whether or not any action is required when an informational event
is logged depends on the environment in which the SAN Volume Controller is
deployed in. In some environments, some informational events are considered
a condition that must be rectified, for example, the space-efficient
VDisk space
warning.
Configuration data
Configuration data is
logged when a configuration event has occurred.
Audit log
An audit log records configuration
command actions that are issued through a Secure Shell (SSH) session
or through the SAN Volume Controller Console.
The log entries can provide information such as the user who issued
the action command, the name of the command, and a time stamp of when
the command was issued on the configuration node. The audit log records
only successful changes.
