Conditional Tokens
ZFIL-TKN-STACKBASE is the checkpoint base-of-stack.
ZFIL-TKN-SREGISTER is the current S register.
ZFIL-MAP-CHECKPOINTLIST is the CHECKPOINT list passed to CHECKPOINTMANY.
ZFIL-TKN-OLDPRIMARY is the old primary process ID.
Effect
The operation fails. If the backup process took over, the system continues normally.
Recovery
If an error occurred, check ZFIL-VAL-CHECKPOINTSTATUS for information about
CHECKPOINTMANY.
If the backup process took over, this is an informative message only; no corrective action is
necessary.
7: ZFIL-VAL-CHECKSWITCH
A call to the procedure CHECKSWITCH returned a nonzero file-system error code. Either an error
was detected or a backup takeover occurred.

Unconditional Tokens
ZSPI-TKN-ERROR is the standard SPI error token, whose value consists of the fields Z-SSID and
Z-ERROR. Z-SSID is the subsystem identifier ZFIL-VAL-SSID. Z-ERROR is the file-system error code
returned in the error parameter of FILEINFO; it is always is zero because CHECKPOINT does not
return an error code.
ZSPI-TKN-PROC-ERR is the procedure in which the error occurred. Its value is
ZFIL-VAL-CHECKSWITCH (7).
ZFIL-TKN-CHECKPOINTSTATUS indicates the status of the call to CHECKSWITCH. This token returns
a status word in the following form:
MeaningValue

There is no backup or the primary process cannot communicate with the backup;
then
<0:7>=1
file-system error number<8:15>=
Takeover from the primary; then<0:7>=2
