Yes, you have a defective disk. It appears that this disk is part of a disk mirror so the other disk is still working. That means that your system is still working. But you'll need to get the bad disk replaced as soon as possible. The details are very different depending on how the disk is connected.

Re: syslog error

Hi madhuchakkaravarthy


YOu have a LUN with problems.

The system is responding because the LUN ha redundancy.


I don't know what type of storage you use.

But you need to identify the problem it the lun and replace the affected disk's.

Re: syslog error

Look for bolt messages in your syslog.log file. My guess would be that you have a bad disk(s). If the disk is in an array you may have lost the array as well. Take a look at the "When good disks go bad" pdf to see if there's something in it that would help.
