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 Fibre
Channel tape drive or tape library connected to a Network Appliance filer , the logical
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
$WWN
is
replaced with the value of the WWN each time the tape device is opened. For example
a usable raw device name for a
Storage Area Network (SAN) Network Appliance filer
is
nr.$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 device discovery function in
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
standalone

Secure Backup Attach Points" on page 2-18 to learn how to create
attach points for tape devices on Solaris 10 systems
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.
