Factors to consider
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.
Status and Sense Data
Commands sent to a device may be rejected with sense key, code, qualifier as follows:
LOGICAL UNIT NOT CONFIGURED: 68 00 00
LOGICAL UNIT NOT SUPPORTED: 25 00 00
LOGICAL UNIT NOT READY: 04 03 00
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

• 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.
