CommVault 8, Deprecated Tapes, any way to "undeprecate" them?

[DaveTANU]

I have had a large number of tapes marked as Depreciated and Bad due to a fault with the tape library. The message being too many Media Label errors. I have read in a number of places to get them back, delete them and re-introduce them. However only to do this with tapes that have no data on them. All of my tapes have data on them. I have also attempted to increase the threshold which did not clear the error.

I have not been able to find any information on how to deal with tapes with data on them. They will not expire the data for some time and most of them will have space to append data to them.

You message reads somehow strange. If the message refers to a "Media Label Error" the tape should not contain any data as the OML is just written at the beginning.

Anyway - the best method would most likely be to run a clone of the jobs and to overwrite/relabel/stamp these tapes manually.

To Make it a little clearer, When you do a properties on one of the meda with the error, under the third tab under Usage Info, the "No. Of Media Label Errors" has gone past the the Limit (ie 6). This was caused due to an error with the drive within the library. This has cause the tapes that have data on them to have a status of Bad. I want to reset that value "No. of Media Label Errors" back to 0 as the tapes are obviously not bad. I dont want to have to move the data from them as this will take a long time due to the number of tapes with this error. Unfortunately the error with the drive occured over a weekend so was not picked up.

The only way to reuse tapes that have been marked as deprecated is to delete the tape and then "discover new media." Unfortunately this will also cause the total loss of data that is currently on the tape.

However, if the tape is marked as deprecated or bad in the CommServe, you've already lost the data on those tapes for all intents and purposes.

Sounds like your tape drives need a good cleaning. If they're not cleaned regularly, you will get lots of write errors on media.
