Purpose
Displays the status of CPs that are allocated to TDP.
Syntax
The DI and DIS abbreviations are deprecated.
where:
- IFP
- Specifies that a summary of the “desired” status of all active CPs be displayed.
- IFPnnnn
- CP whose information is to be displayed as IFPnnnn, where nnnn is the device number of the even-numbered CP device, in three or four hexadecimal digits.
- STATE
- Option that is used for diagnostic purposes only and should be used in consultation with Teradata customer support personnel.
Usage Notes
When the DISPLAY IFP form of the command is executed, for each active CP, TDP displays a summary line containing:
- CP name
- The desired status of the CP. Normally this reflects the completion of the last command affecting the CP (STARTED or STOPPED) or that the command is ongoing (STARTING or STOPPING). If the CP is unavailable on the Teradata Database, HALTED or HALTING can appear. Other possible states are:
- COMM LOST indicates that communication has been lost
- SYNC’ING indicates that communication is being restored
- TEMP ERROR indicates that an I/O error occurred
- PERM ERROR indicates that the CP is not currently configured on the Teradata Database
- QUIESCED indicates the number of consecutive requests sent to the Database on a CP without receiving any responses exceeded the value indicated by the DISPLAY LIMIT NORESP command.
When the DISPLAY IFPnnnn form of the command is executed, TDP displays the name and status of the specified CP, plus the number of blocks, messages, packets, and bytes that the CP has sent to, and received from, the Teradata Database.
Note that the DISPLAY IFP command displays the “desired” status, for example, a status that has been set with the START CP or STOP CP command. It might not reflect the current or actual status of the CP it reflects only what the CP has been set to.
