hi, the virtual scsi device is hosted on Linux 2.4 and solaris 10 (x86) is the initiator. Disk formating and mountig is working fine but as soon as we try and run dd 1Gb.... the initiartor copies around 41Mb and after that 'data overrun' ctio-error is recieved on the target side (qla2300)... we are extracting information like data length and lun from the atio/iocb... scsi cdb is also giving the same parameters... can some one advise me why exactly is the error coming? can it be due to mis-calculated data length on the target side? ___________________________________________________________ Yahoo!
