¾ Zoning: Verify the Expander(s) are zoned properly so that the

ExpressSAS Raid card and the SAS/SATA drives have access to one

another. If there are pre-existing zones setup, be sure to add the

ExpressSAS Raid to the zone.

¾ Port Visibility: Verify the Expander can see the ExpressSAS Raid card

on the port(s) in question. Refer to the Expanders manufacturer’s guide

for more detail on this step.

¾ Speed Auto negotiation: Verify the Expander is set to “Auto” negotiate

transfer speed.

B.) Error Log Capabilities

The ATTO ExpressSAS Raid driver logs all failure related information to an event

log. The user can control the classification of events that are recorded via a

command line argument for Linux.

The driver records events broken into the following classifications.

• FATAL Records various fatal situations within the driver and controller.

• SAS Records SAS errors as reported by the controller.

• ISP Records errors as reported by the FW of the controller.

• LOOP Records event notifications as reported by the FW.

• INFO Records events related to the starting and restarting of the driver.

We recommend Event Logging only be active for troubleshooting purposes as

performance will be affected. Also, when in this mode of operation, all flags be enabled.

To enable the advanced event logging features of the ATTO ExpressSAS Raid

Controller in a Linux environment please do the following:

• Stop any operations or programs using the esasraid driver such as: mounted

drives, Configuration Tool, or attocfg module.

• Remove the driver (rmmod esasraid)

• Load the driver with event logging enabled (modprobe esasraid

event_log_mask=0xfffffff)

• The output can be obtained from dmesg.

To disable event logging under Linux, simply remove the driver with the event log mask

and reload the driver normally.
