the Diamond zoning configuration after power-

The Planned configuration becomes the Active

configuration is replicated as the Planned 
configuration after the successful

replication eases incremental modifications to the 
current zone configuration: you only need to enter 
changes. Modifications to the Planned 
Configuration made before

persistent and are lost in the case of power-up. 

To determine what is in the Active Configuration, 
type 

Several factors must be considered when 
configuring a Diamond-VT with zones:

•  Be careful when changing Diamond-VT zoning 

configurations. Internal validation logic cannot 
detect misconfigurations.

•  The Diamond-VT zoning may be driven by 

external applications which handle 
considerations such as aliasing of parameters. 

•  Stopping or pausing I/O operations during 

zoning changes is the responsibility of the host 
computer, external to the Diamond-VT.

•  You must refer to a device by a consistent LUN 

across zones in accordance with Fibre Channel 
specifications.

•  RAID configuration changes require planning 

and preparation independent of whether any 
zones are enabled. Such changes affect data 
integrity, and any write to an incorrect LUN may 
result in data corruption.

•  Degraded operation and RAID rebuilding occur 

at a lower level than the Zoning features. SCSI 
command operation continues to operate, and 
you can modify the Zoning configuration via the 
ZoneCommit command at any time.

•  Zone validation of switch/fabric routing is not 

supported. The Diamond-VT operates within a 
SAN environment including host systems, host 
bus adapters, switches and other devices. The 
Operating System you use may limit zoning 
flexibility in your SAN.

•  You may create up to 32 zones. Each zone may 

have up to two ports, up to 24 devices and up to 
32 hosts.

Commands sent to a device may be rejected with sense key, code, qualifier as follows: 

LOGICAL UNIT NOT CONFIGURED: 68 00 00

No such LUN exists; the initiator does not have access 
to this LUN

LOGICAL UNIT NOT SUPPORTED: 25 00 00

The Logical unit is not in an accessible zone

LOGICAL UNIT NOT READY: 04 03 00

The Logical unit is in an accessible zone, but is not 
ready; it may be offline or busy

If the logical unit inventory changes for any reason, including completion of initialization, 
removal of a logical unit, or creation of a logical unit, the device server generates a Unit Attention 
command for all initiators, telling them a 

 procedure has been successful. The device 

server sets the additional sense code to 

REPORTED LUNS DATA HAS CHANGED: 3F 0E 00 (LUN has been added to or removed from the zone)
