Hi

10GB / hour seems very low.

An LTO drive is capable of delivering 15MB/s, or 54GB/hour
uncompressed(30MB/s compressed or 108GB/hour).

Some things that may slow things down is if you're using compression on
your clients, have hardware compression turned on and so on.

I'd suggest you diagnose your SCSI connection. Somethings seems to be
wrong, and this is also confirmed by the error message you get
when trying to upgrade the firmware.

Have you got anything else on the same SCSI bus?

Or have you got more than 2 drives on each SCSI bus?

Best Regards

I Have LTO 3583 and using with TSM. I am getting only 5Gb/Hr where as the
spec says it is 10GB/Hr. When i went through the TSM Mailing List Archive
some has suggested to change the tape microcode to 0CE1 from 0BN1. But i
could not locate the file 0ce1.fmr in the site :

 ftp://service.boulder.ibm.com/storage/358x



I got 16E0.fmr in that site but i get error while updating the file through
SCSI bus.

Any one has any idea?.
