I tried posting this to the redhat-list but have not got any responses yet so I will try it here : --- After having upgraded from 5.1 to 5.2 I can no longer position tapes on our two SCSI tapedrives using the mt utility. We have an Exabyte 8505 and a Quantum DLT-4000 on an Adaptec 2940 controller ( aic7xxx driver ) in a P-II. Commands like mt -f /dev/nst0 fsf 2 return immidiately ( without any errors ) but there is no tape movement. Only the `rewind' and the `offline' commands do something. Reading and writing tapes using tar works fine. The problem is not the mt binary itself since it does not matter whether I use the 5.1 ( mt-st v 0.4 ) or the 5.2 version ( mt-st v 0.5 ). The positioning commands all worked with 5.1 ( up to and including the 2.0.35 kernel ) but fail with any of the 5.2 kernels including the latest 2.0.36 ( dec8/98 ). st.c appears to be the same for the two kernels ( .35 and .36 ) but the underlying aic7xxx driver is quite different. If anybody else has experienced similar problems or have suggestions I would appreciate hearing from the. --- Some additional information : RedHat 5.2 uses version 5.1.4 of the aic7xxx driver. RedHat 5.1 used 5.0.19 ( I think ) --- ---- Peter Skensved Email : peter@SNO.Phy.QueensU.CA Dept. of Physics, Phone: (613) 545-2676 Queen's University, Fax: (613) 545-6813 Kingston, Ontario, http://sno.phy.queensu.ca Canada To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe aic7xxx" in the body of the message
