It seems that only controller c1 is being used for disks in the below output.
From the below c1t1d0 is missing. The "dmesg" output or /var/adm/messages should shed some light to confirm this.
cfgadm -fc unconfigure c1::dsk/c1t1d0 ( i seriously doubt this will work,since this is not showing up in cfgadm output)
To start the led blinking. ( Not all boxes support these , please check syntax too)
luxadm /dev/cxtxdx led_blink
luxadm /dev/cxtxdx led_off
luxadm /dev/cxtxdx led_on

one another hint which may be useful. ( Not technicall at all
)
Try "iostat -En" to identify the working disk serial number & try to match with the existing disks , if the serial number is displayed in the front of the disk you can identify it easily ( in our environment the serial number is pasted on the front as well as on top of the disk)
