Re: [Veritas-bu] Please help me with tape drive issues.....

Interesting that you only saw the 85's with appends in the past.

I have seen the header issues with encryption problems. The problem is if the tape drive drive does not does not have the correct key, it can not read or write the netbackup header on the tape.

The key problem could be a problem with the tape library, or with the path used to transport the key from the kms to the tape drive.

Or a problem with the kms server.

Or trying to use a key that does not exit in the kms server.

Are you using netbackup key management of the keys or .....

No changes.

No new hardware. Same stuff we’ve been running for years.

We are working with the encryption team to see if they are seeing any issues on the encryption side of the house. We have experienced RC=85 before on backups when trying to append to already encrypted tapes.

What, if anything changed or did you add new hardware?

- Are you using SSO?

- What does /tpautoconf -t return?

- What does cat /proc/scsi/scsi show

We also have Encryption in place and we are fighting many issues with RC=84/85/86. Most of what NBU says in the logs is "header block" issue.......How can we have header block issues on over 600 tapes?

Please advise?
