iostat question

hcclnoodles · 10-13-2006, 05:47 AM

Hi there, can anybody help me to understand why on some of my solaris boxes when I type "iostat -En" (as root) it just returns to the next prompt giving me no output at all ? however if I type just "iostat" it gives me the expected single line output ?? heres a snippet ...

Code:

# iostat
   tty       cmdk0         cmdk1           cpu
 tin tout kps tps serv  kps tps serv   us sy wt id
   0    1  55   6    1  1768 192    1    7  3  0 89
#
#iostat -En
#

Any help would be greatly appreciated

Hi,

It should work (does here on a Sun Fire 480R, SunOS 5.9).

Does a iostat -E work?

If so, the -n options uses /etc/mnttab to translate from cXtYdZ to a more readable form.

Not much to go on, but maybe it helps.

I believe you do not get error statistics for IDE disks, while you got them for USB or SCSI ones.

OK Thanks ...Does anybody know what utility i would use to check for errors on IDE disks then ?

That's an iostat bug fixed in the very next Solaris Express release (build 50).
