8.4.6 Setting Queue Depth for AIX LUNs Discovered
At this time, Violin does not ship ODM predefines for the Violin Array for DMP. As a result, LUN queue depth
needs to be set for each of the LUNs discovered by Violin Array. Violin provides a script for this purpose.
Please copy and paste this into a shell script and execute it.
echo " checking for a Violin Enclosure managed by DMP"
ENCL=`vxdmpadm listenclosure all | grep -i vmem | awk '{print $2}'`
if test "$ENCL" = "VMEM"
then
echo ""
echo "Optimizing queue depth settings for discovered Violin LUNs"
echo ""
for disk in `vxdisk path | grep -i vmem | awk '{print $1}' 2>/dev/null`
do
chdev -l $disk \
-a clr_q=no \
-a q_err=no \
-a q_type=simple \
-a queue_depth=255 -P
echo "set queue depth to 255 for" $disk
done
else
echo "VIOLIN DMP enclosure is not detected please install the Array Support
for Violin Arays"
