Hi,
If a RAID controller presents more than 256 LUNs to a host on the same
bus what is the proper LUN format?
00 00 00 00 00 00 00 00 to 00 00 00 00 00 00 00 FF for the LUNs 0 to 255
and
40 00 00 00 00 00 01 00 to 40 00 00 00 00 00 3F FF for the LUNs above
255
or
40 00 00 00 00 00 00 00 to 40 00 00 00 00 00 3F FF for all the LUNs
Also, for the LUNs above 255, is it possible to use 00 00 00 00 00 00 01
00 to 00 00 00 00 00 003F FF format?
Thanks,
Marian
