ATTO Technology FibreBridge 1180E/D Installation and Operation Manual
8.1.8 Serverless backup commands
Serverless Backup is an application that allows data to be copied between two storage devices (Fibre
Channel disks, SCSI disks and SCSI tapes) with minimal intervention from a server.
Serverless Backup uses the Extended Copy
command compliant with T10/99-143rl to allow a
“copy manager” (the FibreBridge) to execute all
of the read and write operations necessary to
move data. Blocks of data are moved directly
from the Fibre Channel storage through the bridge
to SCSI tape or from SCSI storage through the
bridge to the SCSI tape, all at Fibre Channel and
SCSI speeds.
CLI commands are case insensitive (upper and
lower case allowed anywhere).
Commands generally follow a standard format:
[Get | Set] Command [Parameter 1 | Parameter 2] followed by
the return or enter key
XCDevices
Allows the user to get information about the devices used in a particular Extended Copy command specified by the CmdNumber as presented in the
XCStatus CLI command (see below).
Limits:
DeviceType
displays SCSI device type
VendorId, Product Id, SerialNumber
display SCSI inquiry data for each device
DataDirection
specifies whether a device is a data source, a data destination or both.
Action:
none
Information:
get XCDevices [CmdNumber]
Return: [lineCount]

XCError
Retrieves any SCSI sense data returned by an Extended Copy command because of an error.
Limits:
CmdNumber
is the data returned by the XCstatus command (see below).
SCSI Status
,
SenseKey, ASC
and
ASCQ
fields display the sense data returned by the Extended Copy command
If a device also returns sense data, the device’s serial number will be displayed in the
DeviceId
field; its data will be displayed in the
DStat, DSK, DASC
and
DASCQ f
ields.
Any field that does not contain valid data will be filled in with 00.
Action:

HostId
field displays 8-byte Node Name of FC host that issued Extended Copy command
Status
indicates current state of Extended Copy command [Initializing|Active|Done|Error}
