Appendix C: Using the ARC Utility 78

Direct attached drives—The connection is determined by the cable connected to a device, for example CN1 (connector 1) is connected to DEV1 (device 1). For more information, see

Direct-Attach Connections on page 61.

Storage Enclosure Processor (SEP) managed devices—The connection is determined by an active backplane. Box0 (enclosure 0) is connected to slot0 (disk drive slot 0 in the enclosure). For more information, see Backplane Connections on page 61.

Expanders—The connections is determinded by an expander. Exp0 (expander 0) is connected to phy0 (phy 0 within a connector). For more information, see SAS Expander Connections on page 61.

Note: Devices other than disk drives (CDROM, tape drives, etc...) are listed in order after your system disk drives.

Viewing the Event Log

The BIOS-based event log records all firmware events, such as configuration changes, array creation, and boot activity.

Some events are not stored indefinitely—the event log is cleared of any non-persistent events each time you restart your computer; additionally, once the log is full, new events overwrite old events.

To view the event log:

1Start the utility (see page 69).

2Select the controller you want, then press Enter.

3When the utility menu appears, then press Ctrl+P.

4Select Controller Log Information, then press Enter.
