Cleaning tapes
Created: 06 Dec 2011 | 4 comments
Hi,
I have to configure cleaning tapes and have to perform cleaning activity in my environment.
Netbackup version is 6.5.6 and is a linux machine.
So far, I have configured the tape by using advanced option in robot inventory by selecting media type and volume pool as none.
Now I need to use these tapes, please let me know How should I proceed whether I shld use tpclean or any other method.
Please let me know it's urgent
Thanks In advance,
Harmanpreet Singh

If the tape is in the library
If the tape is in the library & configured as a cleaning tape suitable for the drives in question, you should just be able to right-click on the drive & select "Drive Cleaning -> Clean Now"

The tape drives that I have
The tape drives that I have used over the years have always self cleaned whenever a cleaning tape is loaded.
If NetBackup is configured to clean the drive(s) and there is a cleaning tape in the library then NetBackup should load the cleaning tape any time the drive indicates it needs cleaning. (Depending on how/when the drive indicates it needs cleaning may cause NetBackup to freeze a tape.)
I have used Andy's manuall method as well.

[edit] forget the mention "Media Type" should be HC_CLN (at least for LTO cleaning tapes)
From NetBackup V 6.5 (or
From NetBackup V 6.5 (or possibly earlier) NetBackup detects the tape alert from the firmware of the drive and interprets it as approriately.
Based on this it will automatically clean the drive as required
Here is a handy little list of all of the codes, what they mean and what NetBackup action will be taken as a result
The hex codes will be displayed in the bptm log

Don't forget to give a "Thumbs Up" or mark as "Solution" if someones advice has helped you.
Generally, you should never
Generally, you should never manually clean drives - overcleaning damages them.
As mentioned already, when a drive needs cleaning it sends out a 'tape alert' from the firmware of the drive. By default, NBU detects these and you will see them in the bptm log. Once a tape alert is received, NBU will load a cleaning tape.
If the tape alert is not sent, it is a drive/ firmware issue, nothing to do with NBU.
It sounds like you have done a good job setting it up, the cleaning tape density should be the same as the drive, eg hcart3 drives = hcart3-cln tape density, and these tapes must be in the NONE pool.

Martin
