thanks for that, ill try and place a call with technical support today.

It means that Physical Disk 0:1 should be replaced.

 

The best reference I know of for sense keys, codes and qualifiers is on the T10 web site. The list of common codes and values is the index to this information. You start by looking up the sense key - 3 is "Medium Error". You then go to the list of ASC/ASCQ (Sense Code / Sense Qualifier) - it's easiest to use the Hypertext ASC/ASCQ numerically sorted page. Click on "0C/00 Write Error" on that page (Sense Qualifier of 00 is the general case), and you can then read off that Sense Code 0C / Sense Qualifier 02 is "Write Error - Auto Reallocation Failed".

 

 

Your controller tried to write to a sector on Physical Disk 0:1. The write failed (so the data was lost - hopefully this is RAID and you have redundancy) because the sector was faulty and the drive couldn't allocate a spare sector, probably because it had run out of spare sectors.

 

Once you get to the point of reallocations failing, the drive is in real trouble. It may well fail completely in very short order - and I would be looking to replace it immediately. If the server is still under warranty, contact Dell - they will probably send you an exchange drive.

 

 

I don't know your hardware and hence your drive numbering; on a 2950 III with a PERC 6/i all the Physical Disks are 32:, as 32: is the enclosure number of the internal backplane. The slots are numbered 0 to 6 on the front panel, and that matches the PERC's Physical Disk numbering. To be doubly sure, you should be able to use the RAID controller's software to 'locate' the disk in question - which will flash the status LED in a distinctive pattern. Exactly how you do this depends on the software you're using to manage the controller.

 

Of course, the drive may already be showing an abnormal status LED pattern because of the likelihood of imminent failure.
