Host manager (HST) messages describe system software conditions associated with host links and internal overlays.
Some messages specify two Ethernet code elements:
Ethernet error codes are described in Table 6-1.

HST messages are described in the following manner:
HSTnnn: Message
Explanation An explanation of the message.
Action A description of the action the user should take.
HST001: Host Manager Initialization Complete
Explanation The host manager processing subsystem was successfully initialized as part of the overall system initialization. All host links defined in the system database are now active.
Action None required.
HST002: Host <host link name> Has Failed Due To: [error name]
Explanation The host link specified failed due to the condition described in the message. This condition can be a physical failure or a protocol violation. No host commands can be processed or reports generated by the system over this link. The message details the internal processing failure. One of the following general socket errors was detected:
Action Further information contained in message HST013 can be used to diagnose the fault. HST002 will appear together with HST013.
HST003: Host <host link name> Restored
Explanation The host link specified was restored to service. This is an advisory message.
Action None required.
HST004: Host Interface <host link name> Has Failed
Explanation The host interface specified (internal, SIO Port 3, SIO Port 4, or Ethernet) failed due to a physical condition (such as the host link connections being physically severed). This condition may affect only a single link or multiple links in the case of Ethernet sockets. Communication between the host and VCO cannot take place over the specified interface. This message may be preceded or followed by other messages indicating the reason for the failure.
Action Take corrective action as appropriate, indicated by the accompanying messages.
HST005: Activate Request For Active Overlay
Explanation The host manager subsystem received an erroneous internal activation request for the TeleRouter overlay (TeleRouter currently enabled). This condition does not affect system processing.
Action None required.
HST006: Deactivate Request For Inactive Overlay
Explanation The host manager subsystem received an erroneous internal deactivation request for the TeleRouter overlay (TeleRouter currently disabled). This condition does not affect system processing.
Action None required.
HST010: Initialization Of Ethernet Interface Has Failed
Explanation The system was unable to establish one or more Ethernet socket connections during system initialization. No Ethernet communication can be performed.
Action Check the physical connections and communication parameters defined in the Host Configuration screen.
HST011: Ethernet IPC <host link name> [error name] $[error code number]:[error code text]
Explanation An internal interprocessing communication fault occurred within the Ethernet subsystem. Refer to Table 6-1 for error code descriptions. The message details the internal processing failure. One of the following general socket errors was detected:
Action Socket write and read errors most often occur as a result of slow reading on the part of the host system. The Ethernet buffer for a connection is not large. If the host experiences delays in keeping the buffer properly emptied, it can fill quickly and inhibit the ability of the VCO to write additional packets to the buffer. When this occurs, ensure that the network segment is not being disrupted by excessive amounts of other traffic which keep the host system from accessing the VCO. Additionally, the host system must not be preoccupied with other tasks with higher priority than reading from the VCO.
HST012: Host <host link> Login Attempt From - [host name]
Explanation The Ethernet socket connection specified in the message was established. This condition only occurs when Password Checking is enabled via the System Features screen.
Action None required.
HST013: Host <host link name> [error name] $[error code number]:[error code text]
Explanation An interprocessing communication fault occurred on the Ethernet connection specified. The message details the processing failure. Refer to Table 6-1 for error code descriptions. The indicated socket (host name) detected one of the following error conditions:
Action
Socket write errors and socket read errors:
Socket write and read errors most often occur as a result of slow reading on the part of the host system. The Ethernet buffer for a connection is not large. If the host experiences delays in keeping the buffer properly emptied, it can fill quickly and inhibit the ability of the VCO to write additional packets to the buffer. When this occurs, ensure that the network segment is not being disrupted by excessive amounts of other traffic which keep the host system from accessing the VCO. Additionally, the host system must not be preoccupied with other tasks with higher priority than reading from the VCO. Other socket errors can occur if the configuration is not correct or an attempt to bind to the socket uses incorrect configuration information. Verify all socket configuration information in the VCO Host Configuration screen and in the host system. If problems persist, use a network analyzer to identify the problem.
Admin request errors:
A system administrator logged into the system and changed the data in at least one of the fields in the System Configuration screen.
HST014: Internet Host Ping Failure
Explanation A host that is configured for ping processing (from the Host Configuration screen) is not responding to the pings from the system. Ethernet communications with the specified host may not be possible.
Action Verify physical connections between the VCO and the network segment. Verify host configuration information in the VCO and the host system.
HST015: Internet Host Ping Failure Has Cleared
Explanation This alarm is raised when HST014: Internet Host Ping Failure has cleared. Ethernet communications with the specified host have been restored.
Action None required.
HST016: Network of Host <host link> [host name] Unreachable
Explanation The SDS/VCO is trying to communicate with a host that is configured outside the SDS/VCO system's network. Ethernet communications between the VCO and the specified host is not possible.
Action Verify the host configuration parameters in the VCO. Ensure that the appropriate Ethernet configuration is entered on the VCO. Ensure that the host system is on the appropriate Ethernet segment and is configured with the correct IP address. Verify all physical connectivity.
