Appendix C: Using the Adaptec RAID Configuration Utility 114

Identifying Disk Drives

You can identify disk drives by viewing the list of disk drives on your system. Only physical drives that display during POST are shown.

To identify a disk drive:

1Start the ARC utility (see page 105).

2Select the controller you want, then press Enter.

3Select Disk Utilities.

The Disk Utilities view will provide you with the following information:

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 92.

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 92.

Expanders—The connections is determined by an expander. Exp0 (expander 0) is connected to phy0 (phy 0 within a connector). For more information, see SAS Expander Connections on page 93.

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 ARC utility (see page 105).

2Select the controller you want, then press Enter.

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

4Select Controller Log Information, then press Enter. The current event log opens.
