Re: Disk read Error

Hi,

Do you get any i/o errors from the disk anywhere other than cstm info?

You can use dd to verify the disk integrity

#dd if=/dev/rdsk/c1t5d0 of=/dev/null bs=1024k

The above command will read the entire disk and produce the output. It will give error if any bad sectors are there.
Best wishes,

Ganesh.

Re: Disk read Error

This may be an early indication of disk failure. It is always better to plan for a disk replacement before it becomes completely dead.

Re: Disk read Error

apart from read error ,in terms of a write error I believe there is nothing so much except replace HDD.

As Ganesan said run the below command
#dd if=/dev/rdsk/c1t5d0 of=/dev/null bs=1024k

What is the output of this command.
Did you see any errors ?
