Parameters
ErrorMode
Optional. Specified as a decimal representation of a hexadecimal bitmask. Values must be specified in decimal format. The following table shows the possible values.Value Name Description 0 (0xnnnn0000)
DAERH_ABORT
Default. The abort-on-error mode stops the command file from processing further.
32768 (0xnnnn8000)
DAERH_IGNORE
The ignore-on-error mode continues by processing the next command when an error occurs.
32769-33023 (0x000080xx where xx!=00 is the number of retries)
DAERH_RETRY_WITHIGNORE
The retry-on-error with ignore mode retries the offending command up to 255 times. If the number of retries exceeds the retry count, this mode continues processing the next command.
1-255(0x00xx where xx!=0 is the number of retries from 1-255)
DAERH_RETRY_WITHABORT
The retry-on-error with abort mode retries the offending command up to 255 times. If the number of retries exceeds the retry count, the command file processing halts.
65536 – 4294901760(0xFFFFnnnn where FFFF is the delay mask in seconds)
DAERH_DELAYMASK
The delay error mode value is added to either the DAERH_RETRY_WITHIGNORE or the DAERH_RETRY_WITHABORT value to cause a delay between retries. This value is in seconds and has a range between 1 and 65535.
Note
Parsing errors, especially the passing of not valid command parameters, generates an error in DAERH_ABORT error mode. With logging enabled, an appropriate error message is output to the log file.
