Description Tape drives or other SCSI devices may not appear at boot time in the /proc/scsi/scsi file
although they are connected properly (Linux-system specific).
Explanation This problem is caused by the current generic SCSI driver in both supported Linux distributions,
Red Hat Enterprise Linux and SUSE LINUX Enterprise Server.
Workaround Proceed as follows:
1. Add a call to the HP utility hp_rescan by adding the following line to the file
/etc/rc.d/rc.local:
hp_rescan -a
This will update the file /proc/scsi/scsi.
2. Restart the host of the FSE server.
3. Invoke the following command to verify that the host sees the applicable devices:
cat /proc/scsi/scsi
