Reassign one of the drivers to a different interrupt level.
a. Modify the driver’s
.conf
file to reassign the interrupts for one or more drivers to a different
level.
This example reassigns the igb driver to level 5 by adding the following line to
/kernel/drv/igb.conf
.
interrupt-priorities = 5;
b. Reboot the system.
The server displays POST messages, and interrupts are assigned to the new level.
c. View the boot messages or the contents of
/var/adm/messages
for the error messages
similar to those shown in Step 1.
If no error messages appear, the procedure was successful.
After reassigning the interrupts, to view the reassigned interrupts, run the
mdb -k
command.
The following example shows the system from Step 3 after igb has been reassigned to interrupt
level (IPL) 5. As a result, the system is able to assign 24 interrupts to ixgbe.
# devfsadm -C
# mdb -k
