Purpose
Use the discoverdev
command to detect NDMP-attached devices. The command also detects changes in configuration for NDMP-attached devices. Based on this information, discoverdev
automatically updates device configuration for the administrative domain.
Oracle Secure Backup detects and acts on the following kinds of changes:
Devices that were not previously configured but have appeared. For each such device, Oracle Secure Backup creates a new device with a temporarily-assigned name and configures a device attachment for it.
Devices that were previously configured for which a new attachment has appeared. Oracle Secure Backup adds an attachment to each existing device.
Devices that were previously configured for which an attachment has disappeared. Oracle Secure Backup removes the attachment from each device.
Oracle Secure Backup detects multiple hosts connected to the same device by comparing the serial numbers reported by the operating system. Oracle Secure Backup also determines whether any discovered device is accessible by its serial number; if so, it configures each device attachment to reference the serial number instead of any logical name assigned by the operating system.
