Hi all. This is my 1st post, so hopefully I'm at the right place. I have a RedHat 6.2 based PII with an internal IDE and a differential SCSI - aix7xxx based. The SCSI is connected to a box that pretends to be a S/390 (3090?) disk to a mainframe. It allows me to read MF disk formatted data via specialized software that understands the MF VTOC, etc. When the MF changes data on the device, I can't tell Linux to flush the cache without rmmod and insmod of the driver, which kills any current xfers. This code originally assumed a raw disk on SCO, but I don't have raw devices here. 1) Are raw devices a reality? 2) Is there a non-destructive command I can use to invalidate the cache associated with specific disks? With ALL disks? Thanks for reading this far Barry Roomberg ______________________________________________________________________ Philadelphia Linux Users Group - http://plug.nothinbut.net Announcements - http://lists.nothinbut.net/mail/listinfo/plug-announce General Discussion - http://lists.nothinbut.net/mail/listinfo/plug
