iostat -En errors

UNIX Solaris
1

I all,

I would like to know what are the causes of :

-soft error
-harderror
-transport error

and how to avoid and repare them.

I got the iostat out put below:

atng-mm01% iostat -En | grep -i hard
c0t0d0           Soft Errors: 1 Hard Errors: 0 Transport Errors: 0 
c0t0d1           Soft Errors: 1 Hard Errors: 0 Transport Errors: 0 
c2t0d0           Soft Errors: 0 Hard Errors: 0 Transport Errors: 0 
c2t1d0           Soft Errors: 0 Hard Errors: 0 Transport Errors: 0 
c1t0d0           Soft Errors: 126860 Hard Errors: 0 Transport Errors: 190295 
c0t0d2           Soft Errors: 1 Hard Errors: 0 Transport Errors: 0 
c0t0d3           Soft Errors: 1 Hard Errors: 0 Transport Errors: 0 
rmt/0            Soft Errors: 0 Hard Errors: 0 Transport Errors: 0

the c1t0d0 is a DVD

Errors reported on CD / DVD drives can be ignored unless you experience real issues while using them.
