Pre-Job Script - BAT/Powershell and waiting

[mongie]

I'm trying to schedule a tape library inventory to run prior to my weekly tape backup. I've done this via the pre-job script funcitonality.

Problem is, while I know how to make powershell wait for the inventory before closing, I don't know how to get the batch file to respect that powershell is still running...

Powershell is...

Code: Select all

Add-PSSnapin -Name VeeamPSSnapin
Get-VBRTapeLibrary | Start-VBRTapeInventory -Wait

Batch File is...

Code: Select all

@ECHO OFF
Powershell.exe -ExecutionPolicy ByPass -File "C:\Program Files (x86)\Veeam\runVBRInventory.ps1"
EXIT

Any suggestions on...

a) how to run a powershell file as the pre job script?
b) how to get the batch file to run until the inventory has finished?


Thanks

You can run a Powershell script directly (without a batch file) using syntax similar to this in the pre/post-script settings:

Code: Select all

C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -noninteractive -file "C:\Program Files (x86)\Veeam\runVBRInventory.ps1"

I guess I haven't tried it with spaces + quotes, but I'd think it would work just fine, but I usually just stick my scripts in C:\Scripts to keep the path short and provide a standard location.

Worst case you should be able to edit the batch to use start like:

Code: Select all

@ECHO OFF
start /wait Powershell.exe -ExecutionPolicy ByPass -File "C:\Program Files (x86)\Veeam\runVBRInventory.ps1"
EXIT

Thanks for the suggestion, unfortunately both methods still don't work. I also changed the path of the scripts as you suggested with no luck.

Can you elaborate on what exactly didn't work as expected? The script didn't get executed? Did it fail with some message? Did work incorrectly? Or something else? Thanks.

1. Tape backup starts,
2. Pre-job script is marked as successful (almost immediately)
3. Inventory doesn't start (even though it does when I run the script manually).
4. Tape job continues without inventory having run.


What I want to happen is...

1. Tape Job starts
2. Pre-job script starts - tape job waits for the task to complete
3. Inventory job starts (triggered by pre-job script).
4. Inventory completes and tape job continues.

There are two obvious feature requests here too...

a) Ability to schedule an inventory job
b) Ability to automatically run an inventory before a tape job - via gui options.

2. Pre-job script is marked as successful (almost immediately) 3. Inventory doesn't start (even though it does when I run the script manually).

Most likely, backup service account doesn't have sufficient permissions. Thus, the script got started, did nothing and ended.

As to the feature request, those should be better submitted on tapes subforum to draw sufficient attention.

Thanks.

Where is the service account defined?

Add this to the end of the script to see what errors come up.

Code: Select all

$error > c:\logs\errorlog.txt

Provided that c:\logs directory exists

Where is the service account defined?

Account under which backup service is running. Thanks.

C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -noninteractive -file "C:\Program Files (x86)\Veeam\runVBRInventory.ps1"[/code]

I wonder if the entire path to powershell.exe is needed. One doesn't when running tasks from the scheduler - the search path must include that folder. Guess there's one way to find out
