Matching Devices to Device Names

These topics explain how to identify drives and other devices on the server with names that are
recognized by or displayed by software and firmware. The same physical device is known by
different types of names in different contexts.

Importance of Matching a Physical Device to a Name

These are some situations when you must correlate a logical device name with the device's
physical location:
When downloading the OS over a network, you must specify the logical device name of the
■
drive in slot 0 (the default boot device).
When you run the Oracle Solaris format command, you must select one of the logical
■
device names presented in the output. To ensure that you select the correct drive for an
operation, you must correlate these logical device names with the physical drives.
When you see a system message that lists a drive's logical device name, you might need to
■
identify the physical slot in which the drive is installed.
