Snapshot properties
When you select the Snapshots component a table shows each snapshot's name, serial number, source
volume, snap-pool name, amounts of snap data, unique data, and shared data, and vdisk name.
• Snap data is the total amount of data associated with the specific snapshot (data copied from a source
volume to a snapshot and data written directly to a snapshot).
• Unique data is the amount of data that has been written to the snapshot since the last snapshot was
taken. If the snapshot has not been written or is deleted, this value is zero bytes.
• Shared data is the amount of data that is potentially shared with other snapshots and the associated
amount of space that will be freed if the snapshot is deleted. This represents the amount of data written
directly to the snapshot. It also includes data copied from the source volume to the storage area for the
oldest snapshot, since that snapshot does not share data with any other snapshot. For a snapshot that
is not the oldest, if the modified data is deleted or if it had never been written to, this value is zero
bytes.
Schedule properties
When you select the Schedules component a table shows each schedule's name, specification, status, next
run time, task type, task status, and task state.
A second table shows details including the last error message (if any), source volume name and serial
number, prefix, number of times run, and the last item created.
Configuration limits
When you select the Configuration Limits component a table shows the maximum quantities of vdisks,
volumes, LUNs, disks, and host ports that the system supports.
Licensed features
When you select the Licensed Features component a table shows the status of licensed features.
Version properties
When you select the Versions component a table shows the versions of firmware and hardware in your
system.
Viewing the system event log
In the Configuration View panel, right-click the system and select View > Event Log. The System Events
panel shows the 400 most recent events that have been logged by either controller. All events are logged,
regardless of event-notification settings. Click the buttons above the table to view all events, or only critical,
warning, or informational events.
The event log table shows the following information:
• Severity.
Critical. Alerts you that the system or a vdisk has a failure that requires immediate attention.
Warning. Warns you that the system or a vdisk has a problem that you should correct as soon as
possible.
Informational. Informs you that either a change was made to the system or a problem occurred that
the system corrected; no action is required.
• Time. Date and time when the event occurred, in the format yyyy-mm-dd hh:mm:ss. Time stamps have
one-second granularity.
• Event ID. An identifier for the event. The prefix A or B identifies the controller that logged the event.
• Code. Event code that helps you and support personnel diagnose problems. For event-code
descriptions and recommended actions, see the Event code reference appendix.
• Message. Information about the event.
