Hi Folks: I wanted to let you know that the 3ware drivers in 9.0 are somewhat out of date. Also, under 9.0 AMD, there is a simple bug in sd.c with regards to signed vs unsigned ints, which limits the size of the SCSI disk system to under 1 TB (1 TB - 1 byte will work, but 1 TB will overflow). See https://www.3ware.com/kbadmin/attachments/sd.c.patch for the patch to sd.c, and look at the knowledgebase article "Q10753 - Software Configuration: Does 3ware have support for 64-bit Linux operating systems?" on http://www.3ware.com/KB/kb.asp. They mention 'There is a bug with 64-bit Linux 2.4 kernels where SCSI disk targets greater than 1 Terabyte in capacity cannot be accessed beyond one Terabyte (1 TByte). The resultant output for the error is: "I/O error: device 08:00 sector X" ' Please include the latest 3ware drivers and the this patch for 9.0 AMD64 kernels if possible. Thanks!
