[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi James,

Here is the boot dump for an x260 with a 3 level cascading expander configuration using the aic94xx driver.  

HBA [94xx]-->expander [Vitesse]-->expander [Vitesse]-->expander [internal]--->end devices [4 disks]

tree /sys/class/scsi_host/host0/device output is also attached.

Regards,

Alexis
