The script can be used for I/O error logging and for extended processing of errors (include external program calls). The feature is available in the Prof. Edition only.
Script can be loaded or modified via Device I/O Parameters (button Script).
The file deviolog.txt is a simple script for I/O error logging.
The file ondevhsc.txt contains a brief description of available commands and some script examples.
Possible script lines are of the form:
IF CONDITION COMMAND
or
COMMAND
or
:LABEL
where CONDITION is an inequality or equality
(!=, >, <, >=, <=, =) of two quantities,
and quantity is either an integer constant (0, 1, ...)
or a variable (the list is below)
or a simple mathematical expression (operators +, -, *, %, /,
without parentheses, ignoring the mathematical order of operators),
e.g. %ERROR%=0
Comments are preceded by two minuses (--)
-- Variables (all are zero based):
-- %CONFIRM% - =1 if Confirm pressed, =0 if Cancel pressed
(dialog box appears and waits for user choice)
-- %DISKNUM% - disk number in RAID array
-- %TRYNUM% - i/o retry number
-- %LBA% - first i/o sector number
-- %SECNUM% - number of i/o sectors
-- %ERROR% - i/o error
-- %LINE% - current line number in script
-- %SERVICE% - i/o service type:
-- 0-ATA 1-ATAPI 3-BIOSINT13OLD 4-BIOSINT13
-- 5-DOSINT25 6-DOSINT73 8-DOSMSCDEX 9-DOSFILE
-- 11-WINFILE 12-WINSCSI 14-WIN9XINT13 20-LINUXFILE
-- %LASTRES% - result of the previous command
-- %LASTERR% - error of the previous command
--
-- Commands:
-- SHOWDLG - force device i/o dialog box popping up
-- WAIT - wait for user choice
-- DELAY N - delay for N msec
-- EXECCMD CMDLINE - execute external command CMDLINE using Command interpreter
(equals "cmd CMDLINE" in Windows)
-- EXECCMDQ CMDLINE - execute without creating new console window (quiet)
-- EXEC "FILENAME" CMDLINE - call external programm FILENAME with parameter CMDLINE
-- EXECQ "FILENAME" CMDLINE - call without creating new console window (quiet)
-- MSDOS - call Command processor (not supported in Linux)
-- GOTO LABELNAME - jump to label LABELNAME in script (to the string :LABELNAME)
-- RETURN - break script execution, handle error according to device I/O params
-- RETRETRY - break script as Retry button pressed
-- RETIGNORE - break script as Ignore button pressed
-- RETABORT - break script as Abort button pressed
-- ADDLOG "FILENAME" LOGLINE - write LOGLINE to file FILENAME
(string LOGLINE may contain variables)
-- CANCELIO - Call CancelIO (WinNT+ only)
(available if a device is opened with overlapped option)
-- OVLRESLT N - Check Overlapped result (N=1: wait; N=0: not wait) (WinNT+ only)
(must be used if a device is opened with overlapped option)
-- RESETHANDLE - Reopen disk handle (WinNT+ only)
--
-- Format specifiers:
-- To format output integer a variable name may be followed
-- by a format specifier after a colon, e.g.
-- %LBA:8x% - width: 8, hexadecimal
-- Script example:
IF %ERROR%=0 RETURN -- return if no error on last i/o
IF %ERROR%=128 GOTO LABEL1
IF %ERROR%=5 GOTO LABEL1
RETURN
:LABEL1
IF %CONFIRM%=0 RETRETRY -- retry if Cancel button is pressed
-- continue script execution if Confirm is pressed
EXECCMD /K ECHO error %ERROR% at LBA: %LBA% (%SECNUM%) try: %TRYNUM%. Type EXIT to return.
IF %TRYNUM%<2 RETRETRY
DELAY 500
ADDLOG "C:\ERRORS.LOG" error %ERROR:x% at LBA: %LBA:10% (%SECNUM%) try: %TRYNUM%
RETIGNORE
