Zone definition tables:
The Zone commands
manage entries in the Zone definition tables
which manage the overall zoning process.
Definition tables are indexed by unique keys
(
zone_name
). All definition tables are
repositories for their respective data and
participate in establishing the configuration by
executing the
ZoneCommit
command.
The integrity of these tables is essential to the data
integrity of the Diamond-VT. If the Zone
definitions are faulty problems can occur.
Although Zone command processing provides a
level of command and configuration validation,
you must be very careful managing
configurations with any zoning system.
Validation of the command line is performed
before the command is deemed acceptable to be
executed.
These descriptions are generalizations.
• Configuration inaccuracies occurring before
application or operating system data is written to
the drives may have no impact on the Diamond-
VT, but results after an operating system or
application have written to the drives are
unpredictable.
• Incorrect Zone entries can include mis-
specification of resources to a zone.
• Verify each command line is properly formed
(number of parameters, proper spelling of
keywords).
• For commands defining entities, the name being
defined must not already be defined.
• If you want to undefine an entity, the name being
undefined must already be defined. (A warning
will be displayed if the name to be undefined
doesn’t exist.)
• World wide port names are validated according
to basic format rules. Content verification of
WWPN occurs at runtime.
• LUN must be in the range defined by the
RAID<n> configuration.
• Errors detected in the CLI command line are
described in Exhibit 7.3-1.
• Errors detected while writing the Active Zone
Configuration result in an error message and no
change to the zoning configuration. The Active
configuration continues to match the persistent
configuration.
• Errors detected while reading the Active Zone
Configuration result in an error message and the
zoning configuration remains unchanged.
