However I could not request more than 256 sectors and could not write more than 1632 inspite of changing MAX_SECTORS to higher numbers. (request_bufflen stands still at 835584 for every command) 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 . Sai __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
