Pinned topic Unreadable Sectors Detected

‏2012-05-29T18:23:22Z |
hi guys

I have a DS5300 latest Firmware.
but it's reporting "Unreadable Sectors Detected" we already replaced drives that were indicated as being the problem with the unreadable sectors...

now the problem is corrected since we check the Unreadable Sector Error Logs is empty... and we already cleared any error with the command line... and still the Storage is alerted, just in case we already tried removing and re-add the storage and same thing...

Check this screen shots

Any idea how to solve this alarm?

thanks a lot

    Could you fix the problem?

    I have the question. I have already replaced fail disks related to fail sectors so I have to clear them. My question is:

    What happen after that this window?? Look picture attached (I repeat I have just replaced the failed disks)

    there will be any checked (immediately) or simply unreadable log will be clear (immediately)??

    Hi Kopper / Rogelio,

     

    Did you managed to solve your problem with the Unrecoverable Sectors? We're currently having the same issue with one of our DS3400.

     

    Regards.

    Hi Guys, I had a similar problem with a DS5300 (Not exactly the same as you). I had  a "degraded path error" in the recovery guru section of the storage manager even after clearing all the error logs. This happened after a drive failure and as far as I understand this was a firmware issue. We have firmware version 7.34 (for some compatibility issues with the hosts we have connected at this time, we can´t  upgrade the firmware). We openend a PMR with IBM and at the end, they told me to boot up the controllers (One at a time) and the problem with the error dissapear.

     

    Hope this helps

    I'm running DS4800 SAN with 8 enclosures, 128 disks.

    I don't seem to get this "Unreadable sector(s) detected" alert when only a single disk fails and I just replace it.

    However recently I had 2 disks in the same enclosure fail about a week apart.

    Even after replacing both disks and the RAID was automatically repaired and the "Hot Spare in Use" deactivated, I got a persistent alert about unreadable sectors.

    I'm guessing that the vxworks operating system doesn't like having 2 disks failed in the same enclosure and same array.

    Recovery Guru says scary stuff about creating support logs, call IBM for support, blah blah blah.

    But the solution is simple: Just clear the logs and the amber warning light goes off.

    In IBM System Storage DS utility just click Advanced > Recovery > Unreadable Sectors.

    Take a good look at it to make sure the logs make sense.

    Then click "Clear" and the alerts go away and the system goes back to Summary "Optimal" green and life is good again....
