Xserve RAID: Reset Controller

Unmount any Xserve RAID volumes hosted by the RAID (especially Xsan volumes).  Press the reset button  on the back of the controller module for about ten seconds.  You should see the controller restart and then the controller should be reset.  Sometimes you need to reset both controllers.  You don’t have to reset the whole controller to just reset the password.  To do that, you can press the reset button for about 1-2 seconds and then try to authenticate through RAID Admin to reset the password.  By default the password to view the Xserve RAID, once reset is public and to edit settings, the default password is private.  By default the IP address is DHCP.  If you plug directly into the RAID then provided you’re both on DHCP it should show up in your list in RAID Admin, which uses Rendezvous.  If you’re not on the same subnet though, it may not open up properly, even if it shows you the RAID in RAID Admin.
