The following storage has been known to report this issue:

Customer is trying to map new LUNs greater than 256 from the IBM Violin array but the Solaris qlc driver fails to configure them.

This is what is logged in the messages file:
Max_LUN=16384 decodes to 0x3FFF , first 2bytes =0xFF = 256
So the Qlogic qlc driver is reporting LUN 300 exceeded maximum LUN 256
