Monitoring Event Logs

Monitoring Event Logs

The ServeRAID controller stores, in the event logs, information concerning various unexpected events.

There are three types of event logs: a device event log, a hard event log, and a soft event log.

To view the event logs:

1.  Click on the adapter (or controller) on the Main Screen of the Administration and Monitoring utility program.

    A screen similar to the following appears.
   

    
   
2.  Select the appropriate button at the bottom of the screen for the event log you want to view.

Device Event Log: The Device Event Log contains event counters for each attached physical device.

Soft Event 
SCSI devices detect these events and reports them to the ServeRAID controller through Check Condition status.

Predictive Failure Analysis (PFA) 
A device has signaled the ServeRAID controller that it might fail in the near future.

Hard Event 
The ServeRAID controller detects these events. Most likely, these events are caused by the ServeRAID controller.

Misc Event 
The ServeRAID controller detects these events. Most likely, these events are caused by the SCSI device, such as selection timeout, unexpected bus free, or SCSI phase event.

Note: Under normal operating conditions, the event logs will contain entries that are not errors.

Hard Event Log: You can view the Hard Event Log.

Logical Drive Number	The number of the logical drive.
Blocked	No - The logical drive is accessible.
	Yes - The logical drive is not accessible.
Part of Array	The identifier of the logical drive's disk
	array (A, B, C, D, E, F, G, H).
Part of Merge	The identifier of the logical drive's merge group (1 through 254)
Date Created	The date that the logical drive was created
State	The current drive state (see 'Logical Drive States' for more information).
Size	The size in megabytes.
RAID Level	RAID level (0, 1 or 5).
Write Policy	WT - Write-through
	WB - Write-back
Read Ahead	Off - Disk Read-Ahead is inactive
	ON - Disk Read-Ahead is active
Stripe Unit Size	The size of each stripe unit per hard disk (8, 16, 32, 64).
Number of Chunks	The number of hard disk drives that make up the logical drive.
Stripe Order	The channel and bay number of the physical drives that make
	up the logical drive

Monitoring the Physical Device Information: You can monitor the physical device information by clicking on the desired device button on the Main Screen of the Administration and Monitoring utility program.

When you click on the device button, a screen similar to the following appears.

 

Descriptions of the information that appears on this screen are as follows:

Channel	The channel to which the device is connected.
Bay	The bay number of the device on a channel (1 to 16).
SCSI ID	The SCSI ID (0 to 15).
Vendor	The drive manufacturer.
Serial Number	The drive manufacturer's identifier.
Size	The size of the drive in megabytes.
State	The current drive state (see 'Physical Device States' and
	'Logical Drive States' for more information.)
Soft Event	The number of soft events reported from the device event log.
Hard Event	The number of hard events reported from the device event log.
Misc Event	The number of miscellaneous events reported from the device event log.
Parity Event	The number of parity events reported from the device event log.
PFA	Yes - Device indicates predictive failure analysis event.
	No - Device does not indicate predictive failure analysis event.
