Re: [Veritas-bu] New tapes are frozen

Leo,

What type of tape library is it? There was a bug in the microcode for IBM TS3200 libraries which caused every new tape to be frozen in NBU the first time it was mounted. I can't find a reference to it now, and don't remember the details. But out short term fix was to run bplabel manually on all new tapes. The longer term fix was to install the latest microcode.

Having said that, I think the IBM TS3200's are actually OEM'd from some other manufacturer, so even if it's not an IBM, it might still be the same hardware, and you might still be seeing the same microcode bug.

Regards
Dean

Hi All

Recently we are having some errors with the tapes. We add some new tapes to the library and inventory successfully (with bar code). However when we run backups, the tapes are frozen, following errors are shown in the bptm log:

io_ioctl: ioctl (MTWEOF) failed on media id XXXXXX, drive index 1, The media is write protected. (19) (bptm.c.23992)

The strange thing is:
1. The tape is not write protected for sure.
2. If i unfreeze the tape and rerun the backup, the tape can be used without any problem, so don't know why we have write error the first time.

The master server is 6.5.5 on Windows 2003 Standard server (64 bit), the tape drive is HP.

Anyone has any idea?

Thanks!

Leo
