Hi, I wanted to increase the number of sectors that could be requested/Written per SCSI READ(10)/WRITE command , and varying MAX_SECTORS in blkdev.h helped me to do it. However I could not request more than 256 sectors and could not write more than 1024 inspite of changing MAX_SECTORS to higher numbers. Why is that? There is probably some other variable that should be varied. Please let me know. I am working on the UNH iSCSI initiator driver , and am on kernel 2.4.29 .
