53 Diamond Storage Array
Configuring Zoning
CAUTION CAUTION
Be careful when changing Diamond-VT
zoning configurations. Internal validation
logic cannot detect misconfigurations
An unrestricted zone configuration, exactly
mimicking the LUN configuration, is created
internally after the first power-up or restart after
installation of the Diamond-VT. No special
operating modes are required and Zoning can be
easily installed with no impact on previous
configurations. The unrestricted zone can be
considered an all/all/all zone: all hosts, all ports
and all devices.
Examples of initial configurations are available in
Sample Zoning Command Sequences in the Appendix
on page ix.
To create a zone
1 The Diamond-VT must be configured to the
appropriate QuickRAID configuration before
applying the Zoning configuration.
Note
Interpretation of the Zoning command is a
single forward pass, so any entities referenced
in any command must have been previously
defined or you will receive an error message.
2 Type ZoneInfo Planned to determine the
status of a Planned Zone Configuration.
3 Type ZoneInfo to determine the status of an
Active Zone Configuration.
4 If you want to start fresh and create zones
without reference to the definitions in the
current Active Zone Configuration, type
ZoneClearAll to remove all entries from the
Planned zone definition table.
5 Create a new named zone. Type
Z o n e C r e a t e z o n e _ n a m e
6 Add the devices, hosts and ports you want to
include in the zone.
ZoneAddDevice zone_name device_lun
ZoneAddHost zone_name host_name
ZoneAddPorts zone_name port_number
7 Enable the zone, type
ZoneState zone_name enabled
8 Type ZoneCommit to make this Planned Zone
Configuration the Active Zone Configuration.
See Sample Zoning Command Sequences in the
Appendix on page ix.
If the Diamond pauses operation by using a
queue while a ZoneCommit command is
executing
1 The Diamond-VT completes any in-process I/O
requests received before the ZoneCommit
command was issued
2 The array performs the zoning changes
3 The array resumes I/O operations.
To remove zones
1 Remove the named zone. Type
ZoneRemove zone_name
2 Type ZoneCommit to commit this Planned
Zone Configuration to become the Active Zone
Configuration.
To change current zones
CAUTION CAUTION
Be careful when changing Diamond-VT
zoning configurations. Internal validation

3 Type ZoneInfo Planned to determine the
status of a Planned Zone Configuration.

5 If necessary, type ZoneRetrieve to overwrite
the Planned configuration with the current
Active configuration.
6 Create or delete named zones as outlined
above.
7 Add or delete devices, hosts and ports as
outlined above.
8 Type ZoneCommit to make this Planned Zone
Configuration the Active Zone Configuration.
