What is the Advantages/Difference between using a Backup software (NBU) or a library to clean the tape drive
Hi
I am looking for useful documents that describe or outline the Advantages/Difference between using a Backup software (NBU) or a library to clean the tape drive.
My Netbackup 6.5 env is connected to an IBM TS5300 that have "automatic tape drive cleaning enabled" but for the past 3 mths the drives keep going "down" randomly.
I have carried out all the usual HW troubleshooting steps ( fibre connections, reset drive path, reboot the library, persistent binding, IBM Engineer on site visit , etc ...) without much sauces. The last IBM engineer to investigate the issue, advised me that this problem has been going on for nearly 2yrs ( I have been there for nearly 3 and 1/2 mths). He also mentioned that this downing drive is linked to the fact the library does not always unload the cleaning tape properly. For some unknown reasons the tape is stuck into the robot.
after gathering all the evidence, I have decided to set up automatic tape cleaning in NBU to see if this can alleviate/resolve the issue. But before going ahead with it, I wonder if someone can help me to find some good literature on the above subject in order to persuade the management why it would be beneficial for us to to try the NBU route.
Much appreciate your help in advance
PS: I am not after how to set automatic tape cleaning in NBU docs.
thanks
