>Have you wondered, item number #2353.523:

How exactly does one convince a Solaris machine to reread its EMC SAN configs using Emulex and Powerpath without rebooting?

  1. Edit /kernel/drv/sd.conf and add the lun. We have two switches so each switch is bound to a different SCSI id. So you just add another lun.
  2. Issue a update_drv -f sd — per Emulex’s documentation
  3. Run devfsadm
  4. Run /etc/powercf -q — note that the -q means “quiet” mode, but powercf won’t seem to run without it (I guess its too polite to be loud in the server room)
  5. Run /etc/powermt config
  6. Run /etc/powermt save

Now, remember boys and girls, these are just my musings and if you’re foolish enough to try to use this as authoratitive information you really are on your own.

Do not taunt happy fun ball.
