Hi guys,
I have been seeing these error on my Sun Explorer portal,

I did read some posts regarding the same, some says they are not harmful and can be fixed to "0" after reboot, so they can be avoided.
is that true?

below is my snapshot showing the same .

Please advise.

If you don't believe others, why are you going to believe what we tell you here? Again, it depends on what those devices are...if they're local disks, you MAY want to look deeper. If not, the errors may be something you can ignore. Have you contacted Sun, and asked them to look at the trace files?

Greetingz!

First, let me address this...

That's not a 'fix'. That's called "avoiding the problem".
All errors reported by iostat -En are reset to zero if you reboot. That doesn't mean the actual problem causing the errors has been fixed.

Hard Errors are typically because of controller, cable, or disk problems.
Since every disk is reporting the problem, I want to say you have a controller going out.
However, it looks like you have two controllers (one onboard, and one Raid 5?)

Keep in mind, any errors on the local disks, excluding CD-ROM/DVD-ROM drives, are worth investigating further.

Example

Here's a server that's been up for 229 days

Code:

user@server$ uptime
  9:32am  up 229 day(s),  8:44,  2 users,  load average: 0.69, 0.66, 0.67
user@server$ iostat -En
