We have been using snapcreator 3.4 on a Windows 2003 server with DB2 v8 and snapdrive 6.3 for months with no problems. The server is a physical server, but we plan to virtualize it in VMware next weekend. I already have an identical clone of the server virtualized to test with in order to ensure everything will work properly. When testing snapcreator everything seems to work but it won't take the snapshot. When I look in the logs, I see this:
Any thoughts on why I'm seeing this error and how to resolve? When I installed snap drive, I did configure it to work with vmware and was able to connect to the drives using snapdrive. The drives are flexclones from snapshot that are not split from their parents though. I had figured, SC shouldn't care since I'm just running through this for the test.
VMs are tricky especially if you are using virtual disks, I dont think SnapDrive can backup virtual disks but you would have to check IMT for what it supports.
You could use SC to backup the VM or VSC and then just forget about SnapDrive. SC if you go that route can do a federated backup where it uses vmwware plugin (vibe) to take vmware snapshot, then quiesces you app in VM, and then takes netapp snapshot. As long as app is installed in VM and not using virtual disks this should work.
Another option is go RDM and just backup the app separately from VM, this is recommended best practice.
Using virtual disks while nice for management is a nightmare to try and backup unfortunately.
Ok, I figured out my problem. I was attempting to do my testing on flexclone's from snaps derived from production. I assumed that since I could snap the sdw volumes in system manger, that snapdrive would be fine with it too. I decided to perform a split on the volumes. After I did that, all worked as expected. If anyone has anything I should be aware of concerning DB2 and snapcreator 3.4 in a virtual environment, please let me know.
