Hi all,
i have run iostat -em, and get below result. Can i know what is this output meaning, and how to fix that problem.
iostat -em
---- errors ---
device s/w h/w trn tot
sd7 0 1 0 1
sd8 1 1 0 2
sd9 0 1 0 1
sd10 0 0 0 0
sd13 0 0 0 0
st11 0 0 0 0
Do you mean iostat -en? Anyway, this information is available to anyone who reads the man page:
-e Display device error summary statistics. The total
errors, hard errors, soft errors, and transport errors
are displayed.
-n: shows the device names in the descriptive format. (cxtxdx instead of sd0, so that we can actually see which disk has the errors).
-m: reports on filesystem mountpoints. I doubt if this will be much use with the '-e' switch.
Thank you for your reply, if this command show that error on HW, how can i troubleshooting HW error, and where is exactly place of this error
