Issue Description
Related information about the product and version: the T3500
The customer installs Linux SLC 4.6 science in the T3500 that is configured with the Areca RAID card. During operation, two RAID groups in the OS reports scsi timeout.
Alarm Information
None
Handling Process
Modify the value of scsi timeout in the Linux SCL 4.6. For details, see 3.10 Setting the Timeout of SCSI Devices Of The T3500.

----End

Root Cause
The value of scsi timeout in the customer's Linux SCL 4.6 is small so that when the disk response to I/O times out, the OS reports scsi timeout before the hard disk is offline.
