Tape Device Names

A tape device can be assigned a logical name by the host operating system (such as
nrst0a), but it also can have a worldwide name, such as
nr.WWN[2:000:0090a5:0003f7]L1.a. On some platforms, such as a
Channel tape drive
name might vary at each operating system restart. Oracle Secure Backup supports
such tape devices, but they must be referred to by their worldwide name, which does
not change across operating system restarts.
Any substring of the raw device name for the attachment that is the string $WWN is
replaced with the value of the WWN each time the tape device is opened. For example
a usable raw device name for a
is nr.$WWN.a, specifying a no-rewind, best-compression tape device having the
World Wide Name found in the device object.
The WWN is usually automatically discovered by the
Oracle Secure Backup. However, you can enter it manually if necessary.

About Configuring Tape Drives and Libraries

This section explains how to configure a tape drive or tape library for use with Oracle
Secure Backup. You can add a tape device in one of two ways:
Manually
■
A tape device connected to a media server on which Oracle Secure Backup is
installed must be added to the administrative domain manually.
Automatically discovery
■
Oracle Secure Backup can automatically discover and configure each secondary
storage device connected to certain types of NDMP servers, such as a Network
Appliance filer.
For both tape drives and tape libraries, you can configure the following attributes:
The name of the tape device
■
The attachment, which is the description of a physical or logical connection of a
■
tape device to a host
Whether the tape device is in service
■
For tape drives, you can configure the following additional attributes:
The tape library in which the tape drive is housed, if the tape drive is not

Note: You must add the media server role to a host before adding
any tape devices whose attachment point references that host. Oracle
Secure Backup does not do this automatically.
