the Active configuration will be copied into the Planned configuration.

To determine what is in the Planned configuration, type ZoneInfo Planned.

Active configuration is persistent and establishes the Diamond zoning configuration after power- up.

The Planned configuration becomes the Active configuration after successful execution of the ZoneCommit command. The Active

configuration is replicated as the Planned configuration after the successful ZoneCommit, after power-up and after ZoneRetrieve. This replication eases incremental modifications to the current zone configuration: you only need to enter changes. Modifications to the Planned Configuration made before ZoneCommit are not persistent and are lost in the case of power-up.

To determine what is in the Active Configuration,

type ZoneInfo.

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

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

LOGICAL UNIT NOT SUPPORTED: 25 00 00

LOGICAL UNIT NOT READY: 04 03 00

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

The Logical unit is not in an accessible zone

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 ZoneCommit 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)

52 Zones
