HP StorageWorks Fabric OS 5.0.0 MIB Reference Guide (AA-RW1QA-TE, May 2005)

230 FibreAlliance MIB objects
connUnitEventObject
OID 1.3.6.1.3.94.1.11.1.8
Description This is used with the connUnitEventType to identify the object to which the event refers. It
can be the OID of a connectivity unit or of another object, like connUnitPortStatus.
Note Always set to null.
connUnitEventDescr
OID 1.3.6.1.3.94.1.11.1.9
Description The description of the event.
Note Same as the string displayed in the system error log. The system error log can be viewed
using the errShow or errDump commands.
Note For Fabric OS v4.x, the format of error messages has changed. This field now uses the
message title and number (for example, WEBD-1006) and the message text. Previously,
this field used the task ID and all of the message number and message text. For more
information on error messages, refer to HP StorageWorks diagnostics and system error
messages reference guide.
Connectivity unit link table
connUnitLinkTable
OID 1.3.6.1.3.94.1.12
Description A list of links known to this agent from this connectivity unit to other connectivity units: X
is switch data and Y is other end.
Note The link table is intended to organize and communicate any information the agent has
that may assist a management application to discover the connectivity units in the
framework and the topology of their interconnect: the goal is to assist the management
application by mapping the elements of the framework in addition to listing them.
With this goal, the agent should include as much as it possesses about any links from its
own connectivity units to others, including links among its own units.
An agent should include partial information about links if it is not able to fully define
them in accord with the following structure; however, the information must include either
a nonzero connUnitNodeId—or a nonzero connUnitPortWwn—for each end of the link.
If the agent is able to discover links that do not directly attach to members of its agency
and its discovery algorithm gives some assurance that the links are recently valid, it may
include these links.
Link information entered by administrative action may be included even if not validated
directly if the link has at least one endpoint in this agency, but it should not be included
otherwise.
A connectivity unit should fill the table in as best it can. One of the methods to fill in
would be to use the RNID els command (ANSI document 99-422v0). This command
queries a port for the information needed for the link table.
This table is accessed either directly, if the management software has an index value, or
using the getNext command. The values of the indexes are not required to be
contiguous. Each entry created in this table is assigned an index. This relationship is kept
persistent until the entry is removed from the table or the system is reset. The total number
of entries is defined by the size of the table.
