Hi.. I am currently doing a project on Virtual tape device along with a couple
of my friends at Sun Microsystems. We are trying to simulate the tape device
systems which is used in companies to take data backups. The idea is that we
should be able to use hard drives/flash drives and make them behave as a tape
device. For this we are writing a pseudo tape device driver and using the LDI
(Layered Driver Interface) to communicate with the hard disk/ flash disk. The
media which we use is abstracted from the pseudo device driver by the LDI
interface. We are writing a header which keeps track of the current read and
write head and several other data. We should make changes in the header after
every read/write/ioctl operation. For this we should perform 'seek' operations
on the read/write head of the hard disk to move from the data back up area and
the header. Since this is in the kernel level fseek functions will not be of
any use. Can anyone kindly help me by suggesting any soluti
on to our problem?
Thank you in advance,
