Raid array Driver returning an Errored I/O, with errno5, on A1000 - Sun Solaris

Greetings, One or more of the hard drives in the A1000 seem to have bad sectors. I get the following error messages: Sep 29 01:24:11 biotools scsi: [ID 107833 kern.warning] WARNING: /pci6,4000/scsi4/sd5,2 (sd578): Sep 29 01:24:11 biotools Error for Command: read Error Level: Retryable Sep 29 01:24:11 biotools scsi: [ID 107833 kern.notice] Requested Block: 1712 Error Block: 1712 Sep 29 01:24:11 biotools scsi: [ID 107833 kern.notice] Vendor: Symbios Serial Number: > Sep 29 01:24:11 biotools scsi: [ID 107833 kern.notice] Sense Key: Hardware Error Sep 29 01:24:11 biotools scsi: [ID 107833 kern.notice] ASC: 0x84 (<vendor unique code 0x84>), ASCQ: 0x0, FRU: ...

    Default Raid array Driver returning an Errored I/O, with errno5, on A1000

    Greetings,

    One or more of the hard drives in the A1000 seem to have bad
    sectors. I get the following error messages:

    Sep 29 01:24:11 biotools rdriver: [ID 486355 kern.notice]
    ID[RAIDarray.rdriver.4003] The Array driver is returning an Errored
    I/O, with errno 5, on a1000_1,

    Lun 2, sector 1712



    I googled for any tips, and found the website regarding SCSI sense Key
    Description, but nothing more specific.



    I know, from the logs, where the bad sector is, on a1000_1, Lun2.
    However, there are four disks in this Lun ,so how do I isolate the
    problem?



    I have also noticed that these errors are spit out only when someone
    sshs to the server. What could be wrong? (Something related to
    /export/home I presume?)



    Thanks for your time and any help is greatly appreciated.

    Try using the `format` command and running diganostics from the interactive
    menus on each disk. There's a pretty good chance one of the disks will turn
    up as the culprit.

    Hmm, format of the lun MIGHT turn up the culprit, but what does healtck
    say? If its a truly bad disk, it will kick it out, and send an event to
    the RM6 and unless you configured it differently then most, a mail to root
    and an event message on the console.

    Try to parity check lun2

    Thats also done from the RM6 tool.

    Thankyou all for your input.
    I used the rm6 and found that LUN 2 was DEAD. Pretty bad ha!
    Fortunately, I had backed everything up and this LUN was not being
    used at all by the server. I revived the LUN and to my surprise the
    data was still there. Is it possible for a LUN to die because 2 of the
    disks failed and had to be replaced in a RAID 5 level? (at the same
    time).
    Regards,
    Shashank
