Drive Rotation Question
We recently expanded our NAS storage. During that time, the storage unit was temporarily offline which wasn't a problem as the data stayed on the LC's for this period. When the NAS came back online, LC2 started writing to a rotation drive. I checked out the help and found this:
Tip: To make a location the active drive, uncheck the Allow Write Access check box on each of the other locations. This forces that location to become the active drive at the top of the hour.
Sounded pretty straight forward. I wanted to keep data off the rotation drive we had set up (as a precaution) and thought if I uncheck allow write access sometime after 11pm, I would have a clean switch back to vol2 (in this case) at midnight and then could move the data from rotation to vol2...in other words a complete day's worth of data, index files, etc would be available to move off of rotation space into vol2 directories.
However, if I look at \logs\datastorage.htm, it looks like the rotation is pending for 6pm tonight instead!! Has anyone discovered a way to control exactly when a storage location can switch? If it would happen at midnight, I'd have a clean switch, if not, the data on the rotation drive is there until expiration.
OK....opened a case with RSA and will just layout what I found.
Drive rotation takes place at midnight (GMT). At 1800 (central time which is -6 GMT) the drives rotated, however, it must have kept data on the LC until after midnight (or something) because all files on the old drive (vol3) are dated 1/12/2010 and/or prior, and all files on the new drive (vol2) are dated 1/13. So it was a clean rotation and I will be able to move the data from the rotation drive to our new, extended NAS space.
I opened a case with RSA on this issue. Here is the outcome.
RSA said drive rotation will happen at midnight (GMT). That's the way it's coded.
So, at 1800 central time (-6 GMT) drive rotation occurred, however, it must have kept data on the LC until after midnight (or something) because all files on the old drive (volx) are dated 1/12/2010 and/or prior, and all files on the new drive (voly) are dated 1/13. So it was a "clean break" and I only have to move the data from volx directories to voly directories and let the locator service rescan to find the data.
