If dynamic reconfiguration isn’t working, there are a number of things to check:

  • Is dr-max-mem enabled in OBP (>=1 for Solaris 2.6; check the text for Solaris 2.5)

  • Ensure that dr shows up in /etc/name_to_major once and only once.

  • Ensure that dr shows up in /etc/name_to_major once and only once.

  • Execute modinfo and look for the dr driver. Execute modload /platform/sun4u1/kernel/drv/dr if it’s not there.

  • Ensure all appropriate patches are installed.

  • Check if /devices/pseudo/dr@0:0 exists. If not, execute drvconfig -i dr to create it.

  • Ensure that /dev/dr exists and is linked to /devices/pseudo/dr@0:0
