returned in the error parameter of FILEINFO; it is always zero, since CHECKPOINTMANY does
not return an error code.
ZSPI-TKN-PROC-ERR is the procedure in which the error occurred. Its value is
ZFIL-VAL-CHECKPOINTMANY (6).
ZFIL-TKN-CHECKPOINTSTATUS indicates the status of the call to CHECKPOINTMANY. This token
returns a status word in the following form:
MeaningValue
No error<0:7>=0
There is no backup or the primary process cannot communicate with the
backup; then <8:15>=file-system error number
<0:7>=1
Takeover from the primary; then<0:7>=2
(primary stopped)<8:15>=0
(primary abnormally failed)<8:15>=1
(primary's processor failed)<8:15>=2
(primary called CHECKSWITCH)<8:15>=3
Invalid parameter; then<0:7>=3
(error in stack-base parameter)<8:15>=1
n > 1 (error in word[n-2];<8:15>=n,

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.
