I am surprised by the short lifetime of such a device and when we have done our choice we expect of course a longer use for it.
Now our vendor propose a storageworks dat 72 external SCSI or another surestore dlt vs80. Our storage needs are about a modest 2 GB per day. So i think that a dat 72 is enough.
I know that these devices could be connected via a USB port.
My questions :
Transfert rate between dat 72 or dlt vs 80 connected with SCSI and with USB ??
Have I to change our SCSI-2 port ??
Tank's for some advices.
Solved! Go to Solution.

Re: surestore dlt Vs80
here you'll find the recommended HBAs for Tape Products
http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?objectID=lpg50063
and here you'll get an compatibility matrix for Tape Produtcs
http://www.hp.com/go/connect
Please also flash your Drive (DLT VS80) again with the latest Firmware and reset the drive by pressing 6sec on the eject button!
If this doesn't works, disconnect the drive from SCSI Bus and check if the tape could be insert.
Otherwise check if the drive has a dropped leader, you can fix this issue by your own, if the leader isn't damage (otherwise you can order spares at Quantum)
Performance
DAT72: Up to 3 MB/s native data transfer rate -- 6 MB/s with 2:1 compression
DLT VS80:3 MB/s (up to 6 MB/s with 2:1 compression)
Cheers
Michael

Re: surestore dlt Vs80
first of all thank's for you reply.
I joined three stickets generated at three points in diagnosis.
First sticket (sticket_header_1.ltt): initial status without tape
Second sticket (sticket_header_2.ltt): after have been trying to load a tape
Third sticket (sticket_header_3.ltt): after immediate reject of the tape.
Thank's again

Re: surestore dlt Vs80
I got just one ticket, and if have the error log filled by the "cannot read the medium "error
I would like to see the other two.
The error "cannot read the medium" mean that the drive is not able to read the header of the tape. There is some incompatibility between tapes format, and if for example your tape has been used in a DLT8000 you will not be able to use it in your VS80 anymore.
My suggestion is to try with a brand new tape, and if it fail with that new tape too, probably the problem is on the Head of the drive. It amy be defective, and you cannot do anything else, or it may be durty, and then try with a non expired cleaning tape.(not supported,but may help if Out Of Warranty, is to try to clean it with apporpriate cleaning products (like for videorecorder)

Re: surestore dlt Vs80
The tapes we are using in our driver have always been used with this drive.
I send the second log.

SolutionOnly a last try, you can try to flash again the FW with the same or previous version and see if something change, and use a new tape, that's all
