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)
