    It could be a reservation conflict (if SENSE DATA contains '0118' in the first row) or something else. One needs to look SESNE DATA you did't post it from the 'errpt -a'.

    Hi,
    You need to immediately make a support call unless you don't care about the data.
    Backup up all the data from that disk.
    Start finding a replacement or migrate data from the disk to others.

    It might turn out to be a temporary problem but better safe than sorry.

      Thanks both,

      the disk is comming from storage and storage guys are saying nothing wrong with storage so I am really confused about this.

      pasting the same data

        http://publibfp.boulder.ibm.com/epubs/pdf/c2343293.pdf

        Page 89

        This is a command timeout, just above the sense data it should tell you the path ID.

        If all the errors are only on one path, and there is more than one path, then you have a SAN connection problem on that path. If the connection is direct then the adapter, connection or storage is probably failing.
