HP P2000 G3 MSA System Event Descriptions Reference Guide 9
Event descriptions
Introduction
This guide is for reference by storage administrators to help troubleshoot storage-system issues. It describes
event messages that may be reported during system operation and specifies any actions recommended in
response to an event.
Events and event messages
When an event occurs in a storage system, an event message is recorded in the system’s event log and,
depending on the system’s event notification settings, may also be sent to users (using email) and
host-based applications (via SNMP or SMI-S).
Each event has a numeric code that identifies the type of event that occurred, and has one of the following
severities:
•Critical: A failure occurred that may cause a controller to shut down. Correct the problem immediately.
•Error: A failure occurred that may affect data integrity or system stability. Correct the problem as soon
as possible.
•Warning: A problem occurred that may affect system stability but not data integrity. Evaluate the
problem and correct it if necessary.
•Informational: A configuration or state change occurred, or a problem occurred that the system
corrected. No immediate action is required. In this guide, this severity is abbreviated as “Info.”
An event message may specify an associated error code or reason code. Error codes and reason codes
are outside the scope of this guide.
Event format in this guide
This guide lists events by event code and severity, where the most severe form of an event is described first.
Events are listed in the following format. Events that do not apply to P2000 G3 MSA System products are
not listed.
Resources for diagnosing and resolving problems
For further information about diagnosing and resolving problems, see:
•The troubleshooting chapter and the LED descriptions appendix in your product’s User Guide
•The topic about verifying component failure in the component’s replacement instructions document
These and other HP documents can be found on the Software Support/Documentation DVD shipped with
your product or at http://www.hp.com/go/p2000/manuals. For links to additional information about your
product, see http://www.hp.com/go/p2000 or http://www.hp.com/go/msa. For product support and to
download drivers, firmware, and software, see http://www.hp.com/support.
For a summary of storage events and corresponding SMI-S indications, see Events sent as indications to
SMI-S clients on page 62.

10 Event descriptions
Event descriptions
1
Warning If the indicated vdisk is RAID 6, it is operating with degraded health due to the failure of two disks.
If the indicated vdisk is not RAID 6, it is operating with degraded health due to the failure of one disk.
The vdisk is online but cannot tolerate another disk failure.
If a dedicated spare or global spare of the proper type and size is present, that spare is used to
automatically reconstruct the vdisk; events 9 and 37 are logged to indicate this. If no usable spare disk is
present, but an available disk of the proper type and size is present and the dynamic spares feature is
enabled, that disk is used to automatically reconstruct the vdisk; event 37 is logged.
Recommended actions
•If a spare of the proper type and size is present, or if the dynamic spares feature is enabled,
reconstruction automatically starts and event 37 is logged. Replace the failed disk and configure the
replacement as a dedicated or global spare for future use.
•If no spare is present and the dynamic spares feature is disabled (that is, event 37 is NOT logged),
configure an available disk as a dedicated spare for the vdisk or replace the failed disk and configure
the new disk as a dedicated spare for the vdisk. That spare is used to automatically reconstruct the
vdisk; confirm this by checking that events 9 and 37 are logged.
•If the replacement disk was previously used in another vdisk and has a status of leftover (LEFTOVR),
clear the disk's metadata so you can assign the disk as a spare.
•Confirm that all failed disks have been replaced and that there are sufficient spare disks configured for
future use.
3
Error The indicated vdisk went offline.
One disk failed for RAID 0 or NRAID, three disks failed for RAID 6, or two disks failed for other RAID
levels. The vdisk cannot be reconstructed.
Recommended actions
•The CLI trust command may be able to recover some or all of the data on the vdisk
4
Info. The indicated disk had an uncorrectable error and the controller reassigned the indicated block.
Recommended actions
•Monitor the error trend and whether the number of errors approaches the total number of bad-block
replacements available.
6
Warning Vdisk creation failed during initialization.
Recommended actions
•Compare the vdisk count with the configuration limit for the maximum number of vdisks.
• If you reached this limit, either purchase additional storage or remove unneeded vdisks.
• If you have not reached the limit, see “Resources for diagnosing and resolving problems” in the
SMU help for the System Events panel, or the CLI help for the show events command.
Info. Recommended actions
•No action is required.
