Subagent Backup Process
Subagent Backup Process
The IPX/SPX Subagent can run as a process pair. At startup, you can use the -b
startup parameter to start a backup process in the CPU you specify. You can also use
the tdmNwSaBackupCPU object to enable or disable the existence of a backup
process. If the primary subagent process fails, the backup process takes over.
Several MIB objects are related to the backup process:
•
The tdmNwSaBackupCPU value can be assigned a value of -1 to disable a backup
process or a value of 0 through 15 to change the CPU in which the backup process
runs.
•
The tdmNwSaBackupPID value is the process ID of the backup process.
•
The tdmNwSaBackupState value determines whether the backup process is
connected to or disconnected from the subagent process.
•
The tdmNwSaBackupStateReason provides the reason for the value of
tdmNwSaBackupState
•
The tdmNwSaSwitchToBackupNow object can be assigned the value
forceBackupTakeover to cause the subagent backup process to take over and
a new backup process to be created.
First Failure Data Capture
The IPX/SPX Subagent is instrumented to send messages to the HP
Tandem Failure Data System (TFDS) when it detects internal inconsistencies.
Standards Compliance
The MIB used by the IPX/SPX Subagent supports one of the five groups defined by
Novell, the ipxSystem group. All the objects in the ipxSystem group are supported, but
only for read-only access. More information on compliance with Novell’s MIB
definitions appears in Novell MIB Objects on page 13-18.
All other definitions in the IPX/SPX Subagent’s MIB are defined by HP and fully comply
with RFC 1155, RFC 1212, and RFC 1213.
