Hi Jennifer, > I removed the node from the collocation group and added it to the > new collocation group The way you did it, or just not part of a group gives the same result. So your way was good, I wasn't trying to say it wasn't, just that you could have saved a few steps and get the same end result. > Will the move nodedata command move the data from the tapes in the old collocation group to tapes in the new collocation group? Yes, but not exactly the way you describe it. Keep in mind that the server is only using collocation settings when writing data, but not when reading it. When reading, it doesn't look at collocation settings, it reads the data from wherever it is. The move nodedata will read the client data and will move it onto new volumes following the collocation settings for the storage pool and the node.

Will the move nodedata command move the data from the tapes in the old collocation group to tapes in the new collocation group? Also, do you know how to initiate a FULL new backup of the entire system. Thanks!

You’ll have to change the mode of the systemstate backup to get a full. Or use move nodedata to move it all together. BTW, you would just have needed to remove the node from the collocation group. Nodes not in a collocation group are collocated by node. Marc...

I created a collocation group and have associated this one node with the new group. This node had previously been backing up to a different collocation group. I created a new Policy Domain and associated the node with it as well. This policy domain is set to send the data direct to tape instead of going to our diskpool. I also modified the settings on the server to allow this system to have 2 mount points. I had the SA launch a "full" manual backup from the GUI - using the "Always Backup" option. Here are the problems I am seeing. 1. I can see that the system state data when to a tape that was already used by other nodes (which tells me the collocation is not working) 2. It only mounted 1 tape in a drive while performing the backup 3. The metrics at the end showed that it inspected 283 GB of data and only transferred 175 GB which means it did not actually perform a full backup. Any ideas to help get a FULL backup of this data alone on a single 1 or 2 tapes and ideally using multiple tape drives to speed things up? (for backup and restore) Thanks! Jennifer
