Betreff: Probleme de reset de chaine SCSI
Bonjour,

J'ai des problèmes de "reset du bus SCSI" sur une machine Linux Mandrake 5.3.
Le problème apparait de façon aléatoire visiblement, mais plus souvent lorsque je fais un backup sur bande.
A la lecture des messages ci-après pourrier vous m'aider ou me conseiller dans l'analyse et la résolution du problème ?
Merci d'avance,
Dominique.

Note: J'ai 4 disques SCSI: 0,1,2, (rien en 3) et 4.
Un lecteur CD SCSI en 6 et un lecteur SCSI de bande en 5 (st0)
