hi,exports

The command "sar -d 5 5" reports nothing
the result is:
14:10:59 device %busy avque r+w/s blks/s avwait avserv
14:11:04

Hi,

What O/S version 10.20 11 ?
# uname -a

What patch level are you on?
# swlist -a revision | grep XSWGR

How many disks are in your system?

Gives us something to start with, as there
certainly seems to be a problem with the
'sar' program itself.

Hi
Try another sar command i.e.

sar -c 5 5

Does that give an output.

Hi,
It seems that, on my systems running HP-UX 11.0, whenever ther is NO activity on disks, 'sar -d' gives no answer...
Try 'iostat 5 5' which seems to be more verbose.

Hi,
It is normal..
If there is no activity on device it will show blank.
Man page of sar also confirms that
"-d Report activity for each block device, e.g., disk or tape
drive. One line is printed for each device that had
activity during the last interval. If no devices were
active, a blank line is printed."

Hope this is clear
