4. On one node, use the RAID Manager GUI’s Recovery application to restore the
controller online.
Note – You must use the RAID Manager GUI’s Recovery application to bring the
controller online. Do not use the Redundant Disk Array Controller Utility
(rdacutil) because it ignores the value of the System_LunReDistribution
parameter in the /etc/raid/rmparams file.
For information on the Recovery application, see the Sun StorEdge RAID Manager
User’s Guide. If you have problems with bringing the controller online, see the Sun
StorEdge RAID Manager Installation and Support Guide.
5. On one node that is connected to the StorEdge A3500/A3500FC system, verify that
the controller has the correct SCSI reservation state.
Run the scdidadm(1M) repair option (-R) on LUN 0 of the controller you want to
bring online:
# scdidadm -R /dev/dsk/cNtXdY
6. Set the controller to active/active mode and assign LUNs to it.
For more information on controller modes, see the Sun StorEdge RAID Manager
Installation and Support Guide and the Sun StorEdge RAID Manager User’s Guide.
7. Reset the System_LunReDistribution parameter in the /etc/raid/rmparams
file to true.
For the procedure on changing the rmparams file, see the Sun StorEdge RAID
Manager Installation and Support Guide.
8. Restart the RAID Manager daemon:
# /etc/init.d/amdemon stop
# /etc/init.d/amdemon start
