Checking your queue depth with kdb.
Just say you
change the queue_depth on a hdisk
with chdev –P . This updates the devices
ODM information only, not its running configuration. The new value will take
effect next time I reboot the system. So now I have a different queue_depth in the ODM compared to the
devices current running config (in the kernel). What if I
forget that I’ve made this change to the ODM and forget to reboot the system
for many months? Someone complains of an I/O performance issue....I check the
queue_depths and find they appear to be set appropriately... [More]
