I searched the archives and didn't find any noice about the Exabyte and wanted to tell someone that it was broke for me. I got a CDB trace? that is not telling me much, but if anyone is interested its attached. I used the following script: ------------------------------------------ dump -0ub 32 -af /dev/nrsa0 /exports sleep 60 mt -f /dev/rsa0 rewind ------------------------------------------ I've got both 2644 and 2618 firmware if someone want me to test something. /Johan > Ken > -- > Kenneth Merry > ken@plutotech.com > ___________________________________________________________ Internet: johan@granlund.nu I don't even speak for myself --Message-Boundary-7355 Content-type: text/plain; charset=US-ASCII Content-transfer-encoding: 7BIT Content-description: Text from file 'sa0.log' Oct 25 00:15:28 phoenix /kernel: Waiting 2 seconds for SCSI devices to settle Oct 25 00:15:28 phoenix /kernel: (pr Oct 25 00:15:28 phoenix /kernel: obe6:ahc0:0:6:0): INQUIRY.
