Re: [Veritas-bu] Odd issues

Len,

Thanks for your response.

I am using IBM LTO4 drives. The IBM model is 3388.

The tape carts are either IBM or Sony, both types have the same issues.

The drives are around 9 months old.

The tape carts are vary in age, none older than 9 months.

There is nothing in the log that says why the tape freezes. I have the log level set to 5 and I sent the logs to Symantec.

No encryption.

No sharing of the tape drives.

The tape library has no errors on it. Checked through the web gui.

Hello Kevin,

Which model of tape drives are you using?

Which model of tape carts are you using?

How old are the tape drives?

How old are the tape carts?

What messages are you seeing in bptm for the tape? You might have to search back a bit from the freezing to find the reason that netbackup is reporting for the freezing.

Are you using encryption?

Are you sharing the tape drives between media servers?

If you use the web interface to the tape library, can you see any errors for the tape drives or the library that match up with these problems?

All,

I have been seeing some odd behavior in my backup environment – OS Linux, NB Version 6.5.5, IBM 3584 tape library.

I have a master server with 6 media servers and media is getting frozen fairly often. I can unfreeze it and it will be used and have no problems, but then another random tape can get frozen. The issue though is not specific to one media server or tape or tape drive.

I have had IBM come in and do a health check on the system and they say there are no issues with the library.

I do have a case open with Symantec, but I was curious if anyone else has seen this issue (or at least something similar to it).

Thanks.

-Kevin
