Appendix C: Using the Adaptec RAID Configuration Utility ● 92
The location information of a disk drive is determined by three types of connections:
● 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 72.
● 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 72.
● 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 73.
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:
1 Start the ARC utility (see page 85).
2 Select the controller you want, then press Enter.
3 When the ARC utility menu appears, then press Ctrl+P.
4 Select Controller Log Information, then press Enter.
The current event log opens.
