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
