jbconfig
jbconfig - jukebox resource configuration toolSYNOPSIS
jbconfig [ -s server ] [ -l ]
DESCRIPTION
The jbconfig program provides an interactive script for configuring a
jukebox (Media Autochanger Device) for use with a NetWorker server.
The script pauses periodically for you to enter a response to a prompt.
If you want to accept the default choice displayed in braces, press
[RETURN] or [ENTER].
After the jukebox is configured, use the nsrcap(1) command or the Reg-
istration window to enter the enabler code for your Autochanger Soft-
ware Module. You must have a separate enabler code for each jukebox you
want to use with NetWorker.
OPTIONS
-s server
Specifies the controlling server, when jbconfig is being used
from a storage node. To define a jukebox resident on a storage
node, the jbconfig command must be run on the storage node. See
nsr_storage_node(5) for additional information on storage nodes.
-l Performs a complete LUN search for all SCSI adapters in the sys-
tem when performing Autodetection. This argument is accepted on
all systems, but does not have any effect on HP-UX systems. Due
to the method used to scan for available devices on HP-UX sys-
tems, all accessible devices are always shown, and the -l option
has no additional effect. On all other systems, the normal
behavior is to start checking at LUN 0 for SCSI deivces. The
first empty LUN found will end the search for a given target ID.
With the -l option, all LUNS present on all target IDs for all
SCSI busses in the system will be checked for jukeboxes. This
can take a very long time and should therefore only be used when
necessary. For example, a Fibre Channel adapter can support 126
target IDs, each of which may have 80 or more LUNs. Checking
all LUNs on this single adapter may take over 10 minutes.
CONFIGURATION DIALOG
The first question jbconfig will ask you, is to select a type of juke-
box to install.
1) Configure an AlphaStor/SmartMedia Jukebox.
2) Configure an Autodetected SCSI Jukebox.
3) Configure an Autodetected NDMP SCSI Jukebox.
4) Configure a SJI Jukebox.
5) Configure a STL Silo.
What kind of Jukebox are you configuring? [1]
Enter the number corresponding to the jukebox type you are
Interface) based jukebox connected to a system that NetWorker
can automatically detect.
Autodetected NDMP SCSI Jukebox is any SCSI (Small Computer Sys-
tem Interface) based jukebox connected directly to a Network
Data Management Protocol (NDMP) Server, that NetWorker will
automatically detect, with the provided NDMP hostname, user-id,
user-password, and jukebox handle. (See example).
An SJI Jukebox is a Standard Jukebox Interface compliant juke-
box. This is a list of well known SCSI based jukeboxes, plus
any additional third party jukebox devices that adhere to this
protocol that the you may have added to the system.
If you select the second choice (Install an Autodetected SCSI
Jukebox), jbconfig will print out a list of jukeboxes it detects
on the system.
For example:
These are the SCSI Jukeboxes currently attached to your
system:
1) scsidev@0.2.0: other, Vendor <AIWA>, Product
<AL-17D>
2) scsidev@2.2.0: DLI Libra Series
3) scsidev@1.4.1: ARC-DiamondBack
Which one do you want to install?
When this message appears, enter the number corresponding to the
jukebox that you wish to configure. Note that if jbconfig was
able to detect only one SCSI jukebox on the system, it will go
ahead and select that jukebox as the one to be configured with-
out waiting for the user to make the selection. This also
applies to situations where there are multiple SCSI jukeboxes on
the system and all but one are already configured in NetWorker.
Even in this case jbconfig goes ahead and automatically selects
the one that has not yet been configured without waiting for the
user to make a selection.
If you choose to install an SJI compliant jukebox, jbconfig will
print a list of known SJI Jukeboxes and will prompt you for the
appropriate type that you want to configure.
For example:
Enter the number corresponding to the type of jukebox you
are installing:
1) ADIC-1200c/ADIC-1200d
2) ADIC-VLS
3) ARC-DiamondBack
4) Breece Hill
5) DLI Libra Series
6) Quantum DLT/Digital DLT
7) EXB-10e/EXB-10h
8) EXB-10i
9) EXB-60
10) EXB-120
11) EXB-210
12) EXB-218
21) ATL/Odetics SCSI
22) HP-Optical 630MB/1.3GB
23) other
Choice?
When this message appears, enter the number corresponding to the
appropriate model, for example, if you are installing an HP
optical jukebox select the number "22".
For all jukebox types, jbconfig prompts you for the name you
want to call this jukebox. This is a convenient way for you to
identify the jukebox for yourself and NetWorker, for example,
'Engineering Autochanger'. NetWorker will store this name as a
NetWorker resource (see nsr_resource(5)). When defining a juke-
box attached to a storage node, jbconfig prefixes the hostname
of the storage node to the beginning of the names using the
remote device syntax ("rd=hostname:"). See nsr_storage_node(5)
for additional information on storage nodes.
For all jukebox types, jbconfig prompts you for a description of
this jukebox. This is another convenient way for you to identify
the jukebox for yourself, for example, 'Engineering 4 Drive DLT
Autochanger on Rack #2'.
For SJI jukebox types, jbconfig prompts you for the name of the
control port associated with the jukebox being configured. For
Silos, this could be the name of the host running the silo soft-
ware (for ACSLS & DAS) or the name of the 3494, depending on the
type of Silo. For Autodetected SCSI jukeboxes, jbconfig detects
the correct name and goes ahead with the configuration. This
name is in the form of libscsi devices (see libscsi(1)). For
SJI compliant jukeboxes, no such detection is done. The name you
enter should either be the device name for the jukebox as
described in any third party SJI compliant driver installed, or
the format used for autodetected jukeboxes. A list of attached
autochangers can be obtained by running the changers(1) command.
Once a control port is entered, jbconfig will check to see if
the model selected is a SCSI or SJI based jukebox. If the juke-
box model is a SCSI or SJI based jukebox, jbconfig will attempt
to query the jukebox about various internal parameters (for
example, number of slots and drives). If this query fails, it is
possible that there is a device driver installation problem or a
hardware problem.
Next, if the jukebox contains tape devices, you are asked if
automated cleaning of devices in the jukebox should be turned
on. If automated cleaning is enabled, the jukebox and all
devices in the jukebox are configured for automated cleaning.
On successful installation, the information that pertains to
device cleaning for the jukebox and all its devices are dis-
played. Note that with the introduction of the Common Device
Interface (CDI), NetWorker now has two events that will cause an
automatic cleaning to occur: schedule-based cleaning, with
devices being cleaned after a certain (configurable) amount of
time has elapsed, and on-demand cleaning, where cleaning is ini-
tiated by TapeAlert warnings issued by the devices. Schedule-
based cleaning is always active when autocleaning is enabled.
At this point, the user has an option of either going ahead with
automatic configuration of the jukebox, accepting all detected
information and default choices as correct, or choosing to cus-
tom configure some or all aspects of the configuration, includ-
ing configuring devices as NDMP or shared devices, configuring
drives that were not detected by jbconfig, or changing the model
type of any of the detected devices. The user can choose to go
the custom configuration route by answering 'yes' to the follow-
ing question:
Do you want to change the model(s) or configure them as shared
or NDMP drives? (yes / no) [no]
If the user chooses the custom configuration option, the user is
given a choice of configuring the drives as NDMP and/or shared
drives. Answering 'yes' to either of the prompts will take the
user to other relevant questions about NDMP and/or shared drive
configuration.
If the user chose 'yes' to configuring NDMP devices, jbconfig
proceeds to prompt the user for this information. NDMP devices
require a user name and password to be entered for each device.
The user name and password correspond to the entries set in the
NDMP server.
If the user chose 'yes' to configuring shared drives, the user
is prompted for multiple device paths for each physical drive in
the jukebox. These device paths would typically be located on
different storage nodes within a data zone, under the control of
one NetWorker Server. Drives or device paths on remote nodes are
to be entered in the "host:<device-path>" form. It's not neces-
sary that all drives in a jukebox be shared drives; entering a
null response to a prompt for additional device paths for a
drive skips that drive and takes you to the next step in the
configuration. A unique 'hardware-id' of the form '<jukebox
name> - <drive no>' is automatically assigned to each shared
instance of a drive. The 'hardware-id' is how NetWorker keeps
track of shared devices. See nsr_device(5) for a description of
the hardware-id attribute.
Next, jbconfig prompts the user for the model of the drives
being configured. In case jbconfig has been able to detect the
model type(s), it will display this information and ask for con-
firmation. If not, it lets the user configure the model for each
drive.
If you selected Autodetected SCSI jukeboxes, NetWorker deter-
mines the name of each media device by sending inquiries for
information to the jukebox. Not all jukeboxes support this capa-
bility, but many do (for example, the Exabyte 210). This
inquiry does not take place when the owning host is different
than where jbconfig is running.
If configuring devices on a remote storage node, jbconfig asks
the user if s/he wants to configure the node on which the device
is being configured as a Dedicated Storage Node (DSN). A DSN is
a node which allows only data from the local host to be backed
up to its devices. See nsr_device(5) for more details on DSN.
ume names should match bar code labels. With NetWorker 7.0 and
later, jbconfig tries to set these attributes either by querying
the jukebox for information or making intelligent guesses. For
Silos, the 'bar code reader' and 'match bar code labels'
attributes in the jukebox resource are set to 'yes' by default.
If it is a jukebox, jbconfig queries the jukebox for this infor-
mation. If both features are supported by the jukebox, it sets
both fields to 'yes.' If both features are not supported, it
sets both fields to 'no.' However, if the jukebox reports that
it can handle volume tags, but has no bar code reader, jbconfig
still sets both fields to 'yes,' since some jukeboxes with bar
code readers tend to report this way. At the end of the instal-
lation jbconfig prints out this information and the user can use
the 'nwadmin' GUI to edit the jukebox resource to set the fields
to 'No' if he so desires.
If the above two fields are set, the label templates will not
be used by the jukebox, and each media volume must have a read-
able bar code label. Note that on some small jukeboxes, like
the HP 1557A or the SONY TSL_A500C, setting 'bar code reader' to
'yes' may cause problems with the labeling. The solution is to
set the appropriate attributes to 'No' as described above.
If the jukebox has been configured successfully you will see the
following message:
