VCB and TSM intergration

[JDLangdon]

Trying to intergrate VCB with TSM and I've run into an issue which I'm hoping someone can help me resolve.

Let me start off by saying that I am very confident that VCB is functioning correctly because the vcbMounter -h {virtual center} -u -p -a ipaddr: -r -t file command does exactly what it is supposed to. I'm also very confident that TSM is functioning correctly because I cam able to backup and restore the VCB Proxy server. The problem is that I cannot get TSM to invoke VCB automatically at the start of a scheduled backup.

I am currently using the "IBM Tivoli Storage Manager Version 5.4 & 5.5 Technical Guide" as my reference point and I have followed the steps up to page 337. On page 338 it reads in step 1 "We run the dsmc backup vm command from the VCB proxy." However, this is where my problem starts.

The exact error message is "Executing Operating System command or script: vcbMounter -h 10.50.201.51 -u vRanger -p **** -a ipaddr:stjh0331 -r C:\mnt\tsmvmbackup\filelevel\stjh0331 -t file 'vcbMounter' is not recognized as an internal or external command, operable program or batch file. Finished command. Return code is: 1 ANS9265E Failure mounting Virtual Machine 'stjh0331' with vcbMounter command. RC=1 ANS9264E Incremental backup of Virtual Machine 'stjh0331' failed with RC 1"

I think the problem is related to the -a ipaddr: section because if I manually type the command using the actual IP address it will work. However, I do not know where or which file needs to be edited to make this change from within TSM.

Any help would be greatly appreciated.

I actually approached this a different way. What I did was wrote and application that will read an ini file for a list of servers and then the application will create the script for vcb and pushing to TSM. I set this up as a scheduled task on the VCB server itself. I was also able to spawn into multiple sessions at once.

The problem is your path. The script can not find the vcbmounter command. Either run the command using the full path, or edit the path settings in your script before you run the mount.

[JDLangdon]

The path statement for the OS includes both the path to the VCB mounter and the path to the TSM client.

[kjb007 · Accepted solution]

Sorry, I meant the path of the profile in which the script executes. From your error, the command was not found. In your script, run the command using the full path to the mount command.

-KjB

[JDLangdon]

That's the problem. I can't find where the script is running from.

Have you been able to resolve this problem.

We have the exact same issues......

My issue was resolved by Suki Singh from IBM.

It seems like the TSM client is unable to find the path to the vcmounter from the registry:

To fix the problem open up 'regedit' and get to the following path:

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{EE247ED5-FD9F-432C-BEBA-458BBAA8766C}

In this path, on the right hand side, will be a key called 'InstallLocation'. I would bet this is blank and shows something like:

"InstallLocation"=""

Update this key with the correct location to the vcbmounter.exe files.

This is typically C:\Program Files\VMware\VMware Consolidated Backup Framework\

but could be different.

Please let me know if you have any questions and if this resolves the problem.

Hope this helps,

Jason

Thanks for the input Jason.

We're testing it as we speak!

One strange thing however (nothing to do with this problem), is that in the automated e-mail I got from the Communities web, the last part of the regkey is not mentioned.

Hi ,

I'm having a similar problem trying to integrate VCB and TSM 5.5

First of all I checked the Registry for the installlocation and is ok.

My problem is that I should have set up all correctly but the backup don't even start .

Here the steps I've followed , taken from the integration guide from IBM.

Installed TSM On the VCBProxy server ( which is also the TSM Server ) .

Installed the VCB integration.

created an opt file and a service for the backup

created a node on the tsm server

tested the vcbmount itself and it works

Tested the following command

:\Program Files\Tivoli\TSM\baclient>dsmc backup serverced3_vm -optfile=dsm_servercd3vm.opt

Make sure you set up the config.js file properly. Also, take a look at this doc regarding setting up TSM ->http://viops.vmware.com/home/docs/DOC-1124

Hi ,

I found that the command I used to check the installation was incorrect

I used

dsmc backup name_of_the_vm -optfile=...\file.opt

instead of

dsmc backup vm -optfile=...\file.opt

but now I have a different problem

Looking at the output below I see that the integration uses the "-ipaddr" option which fail because in the opt we pass the name of the vm .

I tried to set the optin inn the config.js ( VCB ) but it seems to be ignored .

How can I set it in the opt file ?

Also the mount point used is incorrect , I wish to use a different one instead of the default C:\mnt and the type should be "FULLVM"

Where Can I find all the "opt" options related to VM I can use ?

C:\Program Files\Tivoli\TSM\baclient>dsmc backup vm -optfile=dsm_servercd3vm.opt

Again..Check the config.js file. It is located under %ProgramFIles%\Vmware\VMware Consolidated Backup Framework\config

All of the settings you are looking to change are listed in that file.

Hi ,

I've already double-checked the config.js file in the <VCB>\config dir

in the file I've uncommented the following

BACKUPROOT="f:\mnt";

But nothing change .

Moreover I found another post in the ADSM.org forum , which is quit old but already referring to BA 5.5 that states the VCB integration is only for File level backup and that the c:\mnt path is hard-coded.

For FULL-VM is still required the use of pre and post scripts

do you confirm that ?

thanks

[dconvery]

It may be hard coded in TSM, but it is NOT hard coded in the VCB Framework. It will DEFAULT to c:\mnt if you do not set the value in config.js.

What you need to do, however, is use a "double backslash" instead of a single backslash. So the config.js line should look like this:

[code}

BACKUPROOT="f:\\mnt";

Hi

Sorry I mispelled it when posting

it was already set with double \

BACKUPROOT="f:
mnt";

If , as you say , it should read the config.js file it should also be possible to make a FULLVM backup , without using pre and post commands .

Did you manage to do it ?

thanks

[dconvery]

What I said was "It may be hard coded in TSM, but it is NOT hard coded in the VCB Framework."

I have not tried the newer version of TSM to confirm how it works.

Hello,

Just installed a VCB Proxy with TSM 6.1 Server and Client and only had time to send a few test "dsmc backup vm" command to see that it worked....

Also had the "ipadress/name" issue and the destination is "C:
mnt" even if changed in the config.js file. But there's (new in TSM 6.1 ?) a dsm.opt parameter that could help: vmbackdir. I'll try it and tell you.

One thing still hurts me: when saving a "normal" host with TSM, you define mgmt policies and domains. During the save process, the node(s) belonging to a domain see their data sent to the storage pool defined in the mgmt policy. And if the stg pool (Diskpool for example) becomes to grow, the next storage pool defined (say Ltopool) gets the data.

This situation doesn't seem to be the case with VCB. The small i saw (and understood...) is that the VM files are copied to c:
mnt and... that's all. What brings then the "dsmc" command more than the raw "vcBmounter.exe" ?

I would like the mgmt policies defined on node "VCB" be applied and the VM files been sent first to my disk stgpool and then to the tape pool, accrdingly to TSM's configuration.

Thanks for your comments,

Yan

[dconvery]

The process SHOULD be to copy the VM to the mount point and then to tape, diskpool, whatever. TSM may consider the mount point as the final destination disk pool if you are not backing up to tape. I haven't used TSM in quite some time

Dave,

The TSM 6.1 vmbackdir parameter enables to indicate the VM file destination. It overrides the default c:\mnt. And the backup vm command sends, after the vcmounter task, the files to TSM.

But, according to documentation, vmbackdir could pe placed in dsm.opt file, but TSM client fails to start.
