Syntax

In the following example, output of the symdev show command displays the following information about the specified diskless device:

• Device Configuration - shows the device as being an R21 diskless device.
• Device SA Status - always N/A. Diskless devices cannot be mapped to a host.
• Paired with Diskless Device - indicates if the device is in an SRDF relationship with a diskless SRDF device, and the device type for the SRDF partner of this device.
