We are having an issue with our exchange backup not completing. When i go to SnapManager for Exchange and expand the server and go to backup I get this error:

Failed to get Exchange infomation for server - Servername

Error Code: 0xC004025A

[SnapDrive Error]: Unable to locate active virtual disk drives on this system.
{SnapDive Error Code: 0xC004025A}

I looked this up and it says that it cannot access the LUN.

This event shows up multiple times:

Event ID 109 Source SnapManager for exchange

Failed to retrieve LUN list (Snap Drive error) unable to locate active virtual disk drives on this system.

{SnapDive Error Code: 0xC004025A}

This indicates a problem with SnapDrive.

Launch SnapDrive and see if it lists your NetApp LUNs. If it does not, try restarting the SnapDrive service. This can be done without affecting the LUNs.

I would agree with previous comment, make sure SnapDrive is working and services started.  Snapdrive can be uninstall and re-installed without reboot if needed.

Yeah i looked at the ONTAP home page and it is saying that we have a failed disk. I'm willing to bet my paycheck that is the issue.

A failed disk should not affect SnapDrive. You absolutely need to deal with the failed disk, but your SnapDrive/SME issue is likely unrelated. You can continue troubleshooting this while you're sorting out the disk.

Typically a failed disk will not cause this type of issue unless you have several disk fail and you lose an aggregate.

Well we only have one disk failing and we have a new one on order. What else could be the issue? I restarted the SnapDrive service and still received the same error when trying to schedule or look at backups.

How difficult is the re-installation of SnapDrive? I am not too familiar with this system.

Our whole setup is virtual. We have two exchange servers both of which are not getting good backups. We can't even schedule them. Without a full backup exchange all sorts of other issues arise.

It did work but has not worked for a little while. We have two separate networks. Which are set up exactly the same. The exchange on the other network is backing up fine and i am not sure what the issue is.

Have a look in the settings of the Exchange VM in vSphere Client. Are some of the disks listed as "Mapped Raw LUN" or are they all listed as "Virtual Disk"?

Ok, then SnapDrive needs to be able to talk to your NetApp storage array AND your vCenter.

In SnapDrive, right-click on the server name in the right-hand pane and select:

Transport Protocol Info: add your NetApp ocntrollers and specify credentials to access them (or you might be able to use RPC if your NetApps are joined to the domain and you have CIFS configured).

VirtualCenter or ESX Server Login Settings: specify your vCenter address and login credentials (the user needs to have admin privileges in vCenter).

Then go back to SnapDrive and refresh the list to see if your disks are listed.

SnapDrive is a separate application. SnapManager uses it to interact with the NetApp controllers. By default it lives in Start->All Programs->NetApp

It should be installed.  

First you need to enumerate whether you're running straight VMDKs or RDMs.  Snapmanager for Exchange does not support virtual disks, if that's the case you'll need a standard backup software to backup your Exchange or move the Exchange logs and databases to LUNs, either wtih iSCSI out of the VM or RDMs.

We have a netapp fas 270 which has 14 disks and a RAID 6 setup. ESX loaded and the guest operating system (Windows 2003 Server) loaded from there. A also know use iscsi. I apologize again i was gone for awhile when they upgraded to this so i am picking this up as i go.

Not a problem.  The FAS270 is end of life so you probably don't have support.  Can you check on your ESXi hosts if you see all the VMDKs correspond to this VM or whether it's an RDM.  If it a standard virtual machine then Snapmanager will not work.  Take a look at all the drive letters on the Exchange Server and see if you can identify them in the virtual machine propeties.

Wow i figured out what happened. Whoever did our server installation (Not us) removed the snapdrive executable from the SD folder in program files. We are in the military and L3 does our installs. It is installed though. I think i can access the CLI though.

To access ESXi hosts does this mean to console into it or to use the ONTAP web interface? "


"If it a standard virtual machine then Snapmanager will not work."

It was working before and it works on our other network which is setup exactly the same. I have looked through the backup log and they were passing for awhile and now i can't even schedule a new job.

No whoever installed SnapDrive removed the .exe to run it. I can only access the CLI. They did this on all our servers probably so we cannot mess with it. Which is cool unless we have a problem.. like now

Okay i figured it out.

I typed the command sdcli.exe disk list on the working exchange that is on the separate network and it showed a full list of all the disks and drive names.

I did the exact same command on the broken server and got
"No Virtual Disks Exist"

If it is not detecting the LUNS then should i try to mount them first?? I don't think that it is even seeing the FAS 270. I can connect to to it through web interface on the server and see all the disks and LUNS. I think it just may be an issue with SD is not properly configured.

I think i found the issue or at least the cause of the issue. I was looking through the instructions that come with the snapdrive install. Through the CLI instructions. I typed the command "sdcli igroup list -f 192.168.3.50" and it showed "access denied"

I did the exact same thing on the working server and it worked and showed the list.

What could be causing this?

It means that SnapDrive does not have the correct credentials to access the controller.

Run this on a working server to discover how you normally connect to controllers:
sdcli transport_protocol list

This will list controllers and transport protocol and username (if used) for each controller.

Then configure your problem host with the right transport protocol and login credentials using this command:

sdcli transport_protocol set [-m MachineName] -f StorageSystem | -type HTTP| HTTPS |RPC [ -port port] [ -user UserName] [-pwd password]

You can find the full reference for sdcli command more in the SnapDrive Install and Config guide:

I think we may be using a different version. There is no transport_protocol command.

C:\Program Files\NetApp\SnapDrive\SDCLI

The following commands are available:

        sysconfig       disk    snap    snapvault       iscsi_initiator iscsi_target    license preferredIP     spacemon        igroup  spacereclaimer

For more information type "sdcli help <command>"

Oh dear, that version goes back to 2007. I'm not familiar with the authentication models used back then. Have a look at the Admin Guide below, page 44 deals with authentication:

As long as you have a current maintenance contract on your array, you should be entitled to upgrades. Have you got access to NetApp Support website? You might be able to view the details and licensing  for your systems.

In any case, if you have a working host running version 5.0, you should be able to make it work on the problem host. It's an authentication issue, so I suggest you focus on that area.

Do you have an Active Directory domain?
If yes, then RPC might be used for authentication. The service account under which SnapDrive runs needs admin privileges on the NetApp controller.

If not, there might be a local user on the Windows machine and a ONTAP user on the NetApp controller with the same username and password.

Have a look at the Windows and ONTAP users on the working host to see if you can figure it out.

Yeah we have an AD domain and it is saying that RPC is used for authentication. I checked the snap drive account and it has full administrator privileges.

I at least want to find the snap drive install so i can get my hands on the GUI. I can do CLi but it can be confusing at times.

I am looking through the admin guide now.

Question: I understand that there is an authentication issue. Is snap drive supposed to be able to log into the Netapp controller? Should i use the admin account and password used to log in to the controller through the web interface?

Yes, SnapDrive needs to be able to access the NetApp controller to issue commands. In RPC setups, the user account under which SnapDrive service runs is passed through to ONTAP. So you don't need to explicitly specify the password.

Is the service account an AD account? Is the same account used on the working host and the problem host? Can you use this account to manually log into the web interface (FilerView)?

Yes it is a AD account. I log onto ONTAP with a root username and PW. Should i be able to log in with snapdrive? I am honestly not sure what the PW is for the account. I can change it in AD and on the services of course.

I don't recommend resetting the password on the existing SnapDrive AD account as it may be used by other servers.

You can create a new AD account with the following settings:
- member of the local Administrators group on the problem server
- member of the local Administrators group on all NetApp controllers that the server has LUNs on. To add the new new AD account on the NetApp controllers, run this in ONTAP command prompt: useradmin domainuser add <domain\username> -g Administrators

Then use this new account as the service account for SnapDrive.

Okay problem solved. It was an issue with the account. You could log into ONTAP and into the snapdrive account. Apparently the account requires a 14 character PW. I really had no way of knowing this. OH well. It's fixed
