http://src.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/uts/intel/io/dktp/disk/cmdk.c#cmdkattach It fails when the number of blocks on the disk is greater than 0x7fffffff. sd: The code for sd performs the same check but it does log an error when this occurs. http://src.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/uts/common/io/scsi/targets/sd.c Line 7953: /* 32-bit kernels can't handle this */ scsi_log(SD_DEVINFO(un), sd_label, CE_WARN, "disk has %llu blocks, which " "is too large for a 32-bit " "kernel", capacity); Can anyone explain why i386 and amd64 are handled the same way in sd.c? Why isn't amd64 treated separately as it is a 64 bit architecture?
