RAID Device[183]: scrub error detected LBA[1805275136] NumBlocks[4096], ignoring...

Staybox,

 

What you will need to start with verifying the validity of the error, you can do so with the following process.

 

Run the following

 

Raid scrub error Show

 

then review the details of the specific errors with 

 

raid scrub error display <RAID Scrub Error Index> <Controller HSN>

 

validate that the error has a common datapoint to the raid scrub error show command results

 

raid scrub debug showbuffer

Check if the miscompare is on Meta Data with identifier :

 

 raid scrub error display <RAID Scrub Error Index> <Controller HSN> 0 1 ascii 

 

If that all looks good then you can attempt to scrub the Error object to validate that the Scrub Error remains active:

 raid device scrubstripe <RAID Index> scrubstripeaddress <LBA>

 

Check for Scrub Errors on a disk object level:

 

 disk select index ScsiDevice Operstatus RAIDScrubErrors LastSurveyTime
 
Update the Error tables to validate if errors remain after the above (primarily after re-scrubbing individual LBAs).

 

 snap global refreshscruberrors

 

Details the sensecounts for a specific SCSI Device, giving further detail as to what physical objects are responsible for the errors being witnessed.

scsi I device sensecounts show **or** scsi I device sensecounts show where scsidevice <impacted device>

 

Now if all that validates the error and the objects have been confirmed as Metadata, Rescrub of the Error LBA returns with Miscompare, and no major abnormalities are visible, perform the repair actions:

 raid device ScrubStripe <RAID Index> ScrubStripeAddress <Error LBA> ScrubStripeRAIDScrubErrorAction Repair

 

Validate that the LBA now scrubs as clean:

raid Device ScrubStripe <RAID Index> ScrubStripeAddress <Previous Error LBA>

 

Clean up the RAID Scrub Error Object:

raid scrub error delete <Index> <Controller ID> 

 

 

 

After that let me know how it goes and if this helps.
