Hi irshad,

>> UX:vxfs fsck: ERROR: V-3-20005: read of super-block on
>> /dev/vg01/lv_data02 failed: I/O error
The description of the error -

UX:vxfs command: ERROR: V-3-20005: message
->Description
The command attempted to read the superblock from a device, but the read()
call failed. The error message will include the platform-specific message
for the particular error that was encountered, such as "Access denied" or
"No such file or directory".

->Action
The corrective action depends on the particular error.

In this case, there is a IO error on the filesystem.
