In default configuration, the Quantum ATL P-Series tape library is
controlled by a host computer through a SCSI differential bus that uses
the SCSI-2 medium changer command set. There is also an RS-232
diagnostic port interface.
Through the installation of the FC230 Router with Prism
Architecture™, you can easily convert the ATL P-Series library from a
SCSI host interface to Fibre Channel. This document describes the
FC230 router, including configuration procedures common to ATL PSeries libraries.
Note:The term “ATL P-Series” refers to the following ATL Tape
Library™ models: P2000, P3000, P4000, and P7000.
Fibre Channel
Description
For a complete description of ATL P-Series library operating
procedures, refer to the appropriate ATL P-Series Library User’s
Guide.
Fibre Channel is a serial data transfer architecture for use with
0
computers and mass storage devices. Fibre Channel is rapidly
emerging to challenge SCSI as the interface of choice for host-tostorage applications.
Fibre Channel advantages include:
•Up to 500-meter connection range
•1 GB/S data transfer rate
•Support of up to 126 devices on a loop
•Support of 24-bit addressing for over 16 million devices in pointto-point mode or fabric
•Operating system independence
•Interconnect flexibility
•Full direct connectivity between all ports on a network, increasing
the total throughput of all devices on a network
FC230 Router
Operation

Once the FC230 router is installed and tested, the library operates
exactly the same as a ATL P-Series library with a SCSI host interface.
The look, feel, and operation of the library’s graphical user interface
(GUI) panel remains unchanged.
Key to Successful
Configuration of the
FC230
0
The FC230 must be configured using the on-board FC230 router
Services software. The key to successfully configuring the FC230
Option is to know how many:
•SCSI buses are present in the library
•SCSI devices are connected to each bus
FC230 Router Configuration0
The FC230 router configuration includes the following steps:
•Connect a Service PC to the Library
•Start the FC230 Services Software
•Upgrade the FC230 Firmware
•Scan the SCSI Buses

CLI Command Types0
Fibre Channel CLI commands have four types of operation:
•Immediate—causes an immediate action; not preceded by a get or
set operation
•Get—returns the current value of a parameter (abbreviated “g”)
•Set—changes the value of a parameter (abbreviated “s”).
This section provides a list of currently available Fibre Channel
Services Software commands. Most commands are available for both
the FC230 and FC310 bridges; shaded commands are supported by the
FC230 bridge only.
CommandDescriptionDefaultSyntax
AddressMapSets the current operating mode of
the FC ports
AutoMap (Immediate)Automatically maps all currently
operational SCSI devices attached to
the Fibre Channel bridge across 1, 2,
and all 3 ports, as defined by the
user.
BootFibreDelaySets the time in seconds for the Fibre
Channel bridge to wait before
announcing its presence to the Fibre
switch.
BootScanPortsUsed to specify which FC port
should be used to assign devices
within a boot scan.
Addressmap B (port failover)
overrides this command.
ClearEvent
(Immediate)
DisplayEvent
(Immediate)
Clears the contents of the event log.clearevent
Displays the contents of the event
log. The log is filtered by the current
switch settings as described in the
DispEvent section.
Aset addressmap [A | B [1 | 2]]
get addressmap
automap < [fp] | [fp [fp]] | [fp [fp [fp]]] >
(Typing automap by itself distributes maps
across all 3 ports.)
Set the switches which control the filtering performed when
displaying events. Switches have the following meanings and
settings:
(subsystem) switch: mask that controls which subsystem
events are displayed. The mask is a byte value with the
following bit patterns corresponding to the currently
supported subsystems:
0x01 FCP Processor /i960
Interaction
0x02 SCSI Processor/i960
Interaction
0x04 Ethernet (Future)
0x20 NVRAM & Flash
To display the events from several different subsystems, use a
mask value equal to the logical OR of the corresponding
subsystem values. To display events from all subsystems
enter the value 3Fh for the mask.
(event_level) switch: mask that controls what reporting level
events are displayed. The mask is a byte value with the
following bit patterns corresponding to the currently
supported reporting levels:
0x01 Info; general information
0x02 Warning; unexpected situation/condition
0x04 Critical; operation limited/curtailed
0x08 Failure; hard failure
0x10 Other; otherwise not categorized
0x20 Debug; tracking events
To display events from several different reporting levels, use a
mask value equal to the logical OR of the corresponding
reporting levels. To display events for all reporting levels
enter the value 3Fh for the mask.
(status) switch: has the following two values which
correspond to the status of the events to be displayed:
all All events, regardless of their status values are displayed.
ngood Only events with a status other than good are
displayed.
set dispevent [subsystem] [event_level]

Reserve (Immediate)
Reservation of the FC230 is implicit; once the configuration
image is changed by any user of services (Serial/Ethernet/
Etc.,) the FC230 becomes RESERVED. Performing a
SaveConfiguration, RestoreConfiguration or FcRestart
RELEASES the FC230 so that other devices may access it.
When the FC230 services interface is reserved, set commands
are unavailable, but get commands are available. Note that at
least one service interface always has access to the FC230 at all
times. This interface always reports a RELEASED status, since
it may issue set commands.

XCDevices
Allows the user to obtain information about the devices used
in a particular Extended Copy command. The Extended Copy
command to query is specified by the CmdNumber for the
command as presented in the SCStatus CLI command. The
‘DeviceType’ field displays the SCSI device type for each
device. The ‘VendorId’, ‘ProductId’, and ‘Serial Number’
fields display the SCSI Inquiry data identifying the device.
Note that the SerialNumber field displays up to 16 of the least
significant digits of the device serial number. the
‘DataDirection’ field specifies whether a device is a data
source, a data destination, or both as specified in the segment
descriptors of an Extended Copy command; the field can take
on the values [Source | Destination | Both].
Retrieves any SCSI sense data returned by an Extended Copy
command as the result of an error. The Extended Copy
command to query is specified by the CmdNumber for the
command as presented in the XCStatus CLI command. The
‘SCSIStatus’, ‘SenseKey’, ‘ASC’, and ‘ASCQ’ fields display the
sense data returned by the Extended Copy command. If a
device involved in the command’s data transfer also returned
sense data, that device’s serial number is displayed in the
‘DeviceId’ field and that device’s sense data is displayed in
the ‘DStat’, ‘DSK’, ‘DASC’, and ‘DASCQ’ fields. Any field that
does not contain valid data is filled in with 00.
XCStatus
Allows the user to poll for the status of Extended Copy
commands issued to the FC. The ‘CmdNumber’ field presents
a unique identifier for a particular Extended Copy command.
The ‘ListId’ field displays the List ID specified in the CDB of
the Extended Copy command. The ‘HostId’ field displays the
8-byte Node Name of the Fibre Channel host that issued the
Extended Copy command. The ‘Status’ field displays the
current state of the Extended Copy command, which can be
[Initializing | Active | Done | Error]. The ‘Transferred’ field
displays the amount of data transferred by the Extended
Copy command in MB.
