Site Recovery Manager Doubles the Number of Backslashes in the

Command Line When Running Callouts

When a backslash is a part of the callout command line, Site Recovery Manager doubles all backslashes.

Problem

The command-line system interpreter treats double backslashes as a single backslash only in file paths. If the

callout command requires a backslash in a parameter other than a file path and the command does not

convert double backslashes to a single backslash, the callout command might fail with an error.

For example, you can add a callout step to the workflow and enter the following text as a command:

c:\Windows\system32\cmd.exe /C "C:\myscript.cmd" a/b/c \d\e\f \\g\\h c:\myscript.log

As result of the callout step, Site Recovery Manager runs the following command:

c:\\Windows\\system32\\cmd.exe /C "C:\\myscript.cmd" a/b/c \\d\\e\\f \\\\g\\\\h c:\\myscript.log

If myscript.cmd does not change the double backslash to a single backslash, and parameters \d\e\f

and \\g\\h are sensitive to the number of back slashes, myscript.cmd can fail.

Solution

1 Create an additional command-line batch file to contain commands and all required parameters. The

callout step runs this additional batch file without any argument. For the example, the solution is as

follows:

a In a text editor such as Notepad, create a file c:\SRM_callout.cmd with the following content:

C:\myscript.cmd a/b/c \d\e\f \\g\\h c:\myscript.log

b In a recovery plan callout step, enter the command to run:

c:\\Windows\\system32\\cmd.exe /C c:\SRM_callout.cmd

2 Add a code to the original script file that replaces double back slashes with a single back slash.

a Add code similar to the following sample in the beginning of the script file c:\myscript.cmd.

@echo off

set arg2=%2

set arg3=%3

set fixed_arg2=%arg2:\\=\%

set fixed_arg3=%arg3:\\=\%

If you use the shift command in a script, all backslash-sensitive parameters are handled this way.

b If you do not use the shift command in a script, make the following changes:

Replace %2 with %fixed_arg2%.

Replace %3 with %fixed_arg3%.

c Do not change the callout step command.
