Index failing on Full VMDK backups

I use Networker 7.63 mgnt console. I also have a proxy server for image backup jobs. VMware esx 4.1x

The full image backup always completes fine but the index always fails to start. It's the typical warning message about

waiting for a writable volume to backup pool "xxxx" to become available etc.  I've checked the pool/media/parallisem/device settings.

I don't use or want to use different pools for indexes.  Anyone have a suggestion why these indexes don't work?  I'm only running one

job at a time for testing so nothing else is using the device/pool.

Thanks in advance,

SB

I assume you have pool Images.  That one has volume images.001 on storage node.  Pool Images has your group in pool configuration.  When index is to be saved, which is also part of the group run, it looks for volume from pool Images on backup server, but that one does not exist.  Why backup server?  Because index and bootstrap are owned by backup server and backup server will wrote those on backup server and not storage node.

Two ways to remedy this:

- create volume for Images pool on backup server too or

- create pool which will only save index: and bootstrap save sets and will have volume on server of course

I assume you have pool XXXX only on proxy and not on server when index backup happens.  Due to that you get what you get.  Just create one more device and add it to pool XXXX and that's it.

Thank you Hrvoje. I'm looking into that now. I'll let you know what happens.

I tried a few things but no luck. I guess i dont know exactly what you mean Hrvoje. On the media pool what device targets should i have check marked? I have the proxy server device of course. I've also checked Default but that didnt help.  I've made sure the devices are all mounted.

Go to command line of backup server and do nsrmm command and post output here.

Also, I recreated all the proxy items from scratch.  Proxy server, storage node, media pool, device etc.  The first vmdk image backup i did worked as normal but once again the index wouldnt backup. Here's the error message below (FYI... the server CA has *@* access to my Networker server.  Also, the proxy server was setup in datadomain for access.)

ca:index 1 retry attempted

ca:index 39077:save: error, no matching devices for save of client `networker1.actransit.lan'; check storage nodes, devices or pools

ca:index

ca:index 5777:save: Cannot open save session with networker1.actransit.lan

Thank you Hrvoje. I understand what you're saying but i'm stuck on creating a new volume for images pool on backup server. How do you do that?

I have no idea what disk storage do you use, but I assume this is Data Domain due to those dd thingies in name path.

On server you already have:

\\dd01\backup\exchange

\\dd01\backup\windows

\\dd01\backup\default


Now, you can't use \\dd01\backup\images since this is already used by storage node. So, just create folder images 2 so that you have \\dd01\backup\images2 and add it as device (you can copy existing device from backup server and then you just rename path) and as last step just label it to Images pool. If you never did this before, perhaps best way would be to use wizard - in NMC go to Devices section and from there you select add device using wizard option - it will guide you through configuration and it should be easy.

Thank you for taking the time to explain it so i could easily follow.

Go to pool properties and verify that device is checked in pool properties. Also check something that is called preferred media type once there - it might be set to something other than you have, but I think adding device to pool will be enough.

I'm working on this now Hrvoje.  Here's the error i'm getting ...

Adding new AFTD "\\dd01\backup\images2"
  Successfully added new AFTD "\\dd01\backup\images2"
Labeling device "\\dd01\backup\images2"
  Operation Failed
 

labeled but not mounted images.005 (pool disallows mount)

I forgot to let you know that everything you suggested worked. I now have full functioning VMDK backups through my proxy machine. I can do file level and full image restores. I still don't understand why the index files needed a seperate pool though.

Thanks for your help Crvelin.
