problem using psexec with diskpart remotely

by willbs at 2013-03-18 11:15:31

whe i run this code with the literal values for the remote machine name, username and password, it works fine

psexec \ -u Username -p Password cmd /c 'echo . | diskpart /s “D:\serverfolders\documents\MSR-EFItest.txt” > “D:\serverfolders\documents\MSR-EFIlog.txt”'

if i run the same code using global variables, it gets stuck, as if i have the incorrect remote machine name, username, or password

psexec \$global:uutName -u $global:usernamer -p $global:password cmd /c 'echo . | diskpart /s “D:\serverfolders\documents\MSR-EFItest.txt” > “D:\serverfolders\documents\MSR-EFIlog.txt”'

or this too with quotes

psexec \"$global:uutName" -u “$global:usernamer” -p “$global:password” cmd /c 'echo . | diskpart /s “D:\serverfolders\documents\MSR-EFItest.txt” > “D:\serverfolders\documents\MSR-EFIlog.txt”'

any suggestions to get it to work?

Have you tried pushing the double backslash inside of your uutName variable? That would be my first guess as to why it isn’t working with variables.

that was a good guess but it didn’t work

Ok, here’s another way you could do it: try using splatting instead to push the arguments into psexec, like this:
$psexecArguments = @(
‘echo . | diskpart /s “D:\serverfolders\documents\MSREFItest.txt” > “D:\serverfolders\documents\MSR-EFIlog.txt”’
psexec @psexecArguments

You should also verify the contents of the array by outputting it to the console to make sure the arguments are what you think they should be as a part of testing this. If that fails then I can run some tests locally (don’t have psexec installed right now, which is why I’m just putting out suggestions).

hey poshoholic, you got me thinking about pushing the backslashes when it didn’t work
so what i did was remove them from the contents of the global variables and rewrote the command like this

psexec \$global:uutName -u $global:DiskPartusername -p $global:password cmd /c 'echo . | diskpart /s “D:\serverfolders\documents\MSR-EFItest.txt” > “D:\serverfolders\documents\MSR-EFIlog.txt”'

and it works fine

thanks for the idea
