Quantum 8000 DLT Tape Drive

I've just bought one, but I don't have a clue what DLT tapes I should order for it?
DLT III or DLT IV
Or none of the above?

Both will work. The III will take twice as long to write. Buy tapes off EBay for some great deals.

Which DLT Tape Drive for Replicator

Which brand of DLT tape drive is recommended for DVDSP4 authoring? The DVD+R DL discs are good but the replicator would like for me to use a tape drive. Using Mac G5 w/dual 2.7 Ghz Power pc. 2gig ram. Thanks

Hi Ray,
A DLT 7000 (make sure it says "LVD SE" on it somewhere, and that you acquire the proper active terminator, along with an ATTO SCSI card to hook the DLT up to, for installation in PCI slot 2 if you're on a G5) using Type IV tapes will get you the fastest writes, while staying readable by all replicators.
A DLT 4000 (same as above) using Type III tapes is just as compatible with replicators, but darn slow writing in comparison.
A DLT 8000 (ditto) with Type IV tapes is the fastest writing in this legacy class of devices, but some replicators might not have one of those drives around. In that case, an 8000 can be set to write at 35G density (instead of 40G), so the replicators 7000's can read it's output.
Take care,
Trai

Need a DLT Tape Drive?

I have a DLT Tape Drive I was using up until I updated to the latest version of OSX.
I was using it with Retrospect. But now there is an OSX, Adaptec, SCSI, Retrospect issue.
The bottom line is that Retrospect won't work anymore with my setup.
Anyone need a DLT Tape drive.
Save me from doing ebay.

It's probably your Adaptec Card no longer working under OSX. I think the Atto is the only one that will work reliably under the latest OS

Solaris Can't detect Quantum SDLT 320 Tape Drive

Hi All,
I have a Quantum SDLT 320 connected to Sun Fire v490 which can't be detected in solaris but can be detected in OBP .
Can someone help about this issue.
Your prompt response will be very appreciated.

Hi All,
Thanks for your help.
The problem is now solved when i proceeded as followed:
1. When i executed the command cfgadm -al
the output showed the below information about the tape drive controller:
c3 Connected unconfigured OK
I disconnected the controller and then run the devfsadm -c tapes which took about 1 hour to complete and then, now the system can detect and tape and the first backup run
successfully.

Hot swapping DLT tape drives

Is it possible to hot-swap a tape drive on an Enterprise 4000 running Solaris 5.5.1?
I have an E4000 with an array and tape drive attached. The drive seems to be kaput. I can get it to run for a little while, but my cron backups are failing. I've done all the hardware chacking I can (I'm 2500 miles away from the server) and had the on-site techs check the scsi connections, recycle the unit, clean it, et al.
I don't know where in the chain the drive is, or even if it's on the same scsi bus as the array. Is there any way I can find out which bus it's on, and which bus the array is on?
Assuming it's either the last device on the chain attached to the array or on it's own scsi bus, can I swap it with another drive set to the same scsi address?
Thanks,
Mark

As Emily Latilla said, "Never mind..." Answered the question myself.
Thanks

Can anyone give me the DLT tape drive compatibilty list?

Dear All,
I am starting to make some DVD-9 project with DPS4. But I have to purchase a DLT drive. I have no idea which one to buy and I cannot find any information from the site. Please can anyone give me advice. Thanks in advance.
Mac G5 Mac OS X (10.3.9)

Basically all DLt drives are made by Quantum and then rebadged by other manufacturers. The ones to look for are 4000, 7000 and 8000. If you can go for a 7000 or 8000 as i think these wrtite tapes faster and if your replicators accept them use DLT IV tapes as they write faster as well. The drives come up on ebay quite regularly and bargains can be had. I have bought six different drives over the years (some as back-ups just in case) and have never paid more than £100 for them (in the UK)
Don't forget you will also need a SCSI card for your Mac (Atto appear to be the only game in town anymore for Mac G5s) and SCSI leads and maybe an active terminator for the DLT Drive
Hope this helps

Can I connect an external DLT Tape drive to the SCSI connector on an E450

Hi... totally new to SPARC. I have inherited an E450. It appears to have the 8 bay option. I have 6 scsi disk drives installed in slots 0 through 5. Internally, there is one ultra scsi controller in slot 2 and two internal cables running from the top of the card, one for each channel. I do have an extra ultra pci scsi card, but when I plugged it into a pci slot, the system would not boot. Bottom line, can I connect an external DLT drive to either Channel A or Channel B at the rear of the Unit and not intefere with other SCSI devices (i.e. the disk drives). Currently, the DLT is set to SCSI ID 8. If this isn't recommended, how do I install the secondary ultra scsi card and have the system recognize it ? Note that the Hard drives have been wiped and I WILL be loading Solaris 10, but have not yet. I wanted to make sure all of the hardware worked first. The second PCI Scsi controller I have is an Adaptec 39160, and I'm assumming it will work IF needed. I'd prefer not to use it if necessary.... ANY HELP is sincerely appreciated ! Thanks, Randy

I suggest you leave the current internal connections just as they are.
You never know when you'll need to add more disks.
That Adaptec card is for PC's.
It won't work in a Sun SPARC-based system.
What sort of SCSI interface is required for that tape device?
Single-Ended? High Voltage Differential? Low Voltage Differential?
You need a card that matches that interface type if you hope it to "drive" the tape.
One quick way to tell, is to examine the chassis of the tape peripheral
and find the small icon that should be at the port for the SCSI cable.
For example, Sun's 375-0005 card is Single-ended and is what you already have inside your E450.
Sun's 375-0006 is a HVD card and would be correct for A1000 and D1000 arrays or L7 or L25 tape libraries.
Sun's 375-3057 card is LVD and would be appropriate for Sun's D2 array.
The manual for that 375-3057 card happens to have pictures of the SCSI icons I just mentioned.
See page 35 in that manual.
http://192.18.109.11/816-2156-11/816-2156-11.pdf
Once you confirm what's needed by the tape peripheral, we may be able to suggest how to connect it properly.

SE3310 - DLT Tape

I have a Storedge 3310 connected to a X4200 server. Is it possible to attach an external DLT Tape drive to the back of the 3310 array or will I have to install an extra scsi card?

Hi, You basically need a SCSI DLT Tape drive which uses Type III or Type IV tape ( to have copy protection in duplication)
The studio I work at has an old dual g4 because it has PCI slots and a SCSI card.
Final Cut Studio is great until you realize there is no way to output to a SCSI tape drive! I want a new Mac Pro myself but they don't explain how you are supposed to output your DVD project with copy protection...
There should be a hint that says while your at it buy an old SCSI capable G4 or G5 with PCI slots. Even a G5 with its PCI-X slots only has the ATTO $360 card available for use.
Quantum makes most of the DLT tape drives out there. You should contact your replicator to see if they want DLT III or DLT IV tape.
Good luck.

DLT TAPE

Anyone know which exact DLT TAPE machine will work for us? And where to buy?
We are working on a powerbook so I dont think we can use SCSI.
We need to send a dual layer DVDSP project out for replication with copy protection.
(if anyone knows of a way to copy protect doing only duplication please let us know....we have been told its not possible though.)

Testing tape drive

I am trying to write a c program that detects the tape drive and if it's busy or has a tape in it. I used the open function with the path to the driver "/dev/rmt/0" but it always returns 0. Only when i try to do a cpio will the program then let me know if the tape is empty or not. I would like to use a function to test this instead of using cpio. Anybody out there has any ideas ?

check out the ioctl() API for tape devices. i did some work on DLT tape drives a while back and that is what i used.

How can I connect a DLT-IV Tape drive with SCSI interface to Quad G5?

I have had no problems with my "Quantum equivalent La Cie DLT-IV Tape drive" on OSX connected to the G4 Quicksilver using an Adaptec 2930CU PCI card - but I can't move that to the G5 as it has to be PCI-Express cards as far as I can tell.
Adaptec pre-sales support inform me that Adaptec have no Mac support in their current product range.
Has anyone found a solution to this connection requirement that will work with Retrospect and DVD StudioPro?
If there is a workable solution which is no longer available to buy - I would still be interested in knowing so I could scour ebay for it.
TIA,
Richard

Hi Richard;
If you go to ATTO, they are offering a ExpressPCI PSC which include a SCSI bus on sale for $24.11.

Quantum P2000 tape library showing NOBARCODE on tape drive

Hi all,
We are having a tape library of ATL quantum P2000 which is having 4 tape drives.
In which we used to daily backup.
When ever we are keeping any new cartridges into the library we will run an inventory , During this time if their is any kind of cartridge in the tape drive their wont be any issue with that particular tape drive .
If not it is showing a problem of NO BAR CODE on the operator panel of the library.
and at this time it is not detecting on the legato software also.
Kindly help me in this .....
Thanks in Advance....
SWAROOP

I will use new words to repeat my first reply:
You have broken hardware.
Broken hardware doesn't work when you expect it to work.
For example:
but why my tape drive is showing no bar code error when no tape is presentHow can a broken barcode reader give you an error when you don't have anything in the library that has a barcode on it?
Go contact whoever you use for repair services and get the library repaired.

St.conf parameters for SDLT tape drive / Solaris 8

Hello,
I need the parameters for the SDLT tape drive from Tandberg for the st kernel driver. In the st.conf there is no entry for Tandberg SDLT.
With the st.conf, shipped with Solaris 8 10/01, my V880 crashes when accessing the SDLT with the mt command.
Does anyone here have the parameters?
Thanks in advance

Hi Thomas,
Actually, a bug 4495684 has been filed to fix this issue. A 2.6, 7,
8 and SOlaris 9 patch should come out soon that will add this entry
in the st.conf.
I constructed this entries from the bug description. Try if it works.
It should else wait for the patch. Any way, please let me know
the results.

Tape drive and pci-x card with Solaris 10 on VMWare environment

I have a Sun X4170 server (x84_64) running VMWare ESXi 4.0. On it I have two VM guests- my production file server running Solaris 10 U7 and a test file server running Solaris 10 U9.
The X4170 has a PCI-X LSI Logic dual external U320 parallel scsi card. I have a tape drive + auto loader cabled to the X4170. It is a Quantum branded autoloader but I believe the tape drive itself is HP. The autoloader+tape drive share a single SCSI ID (6) but have separate LUNS.
I have two choices for making this system accessible to the OS:
- Virtualize the tape drive and loader individually.
- In VMWare, enable the scsi card as a pass through device. The SCSI card is then added as PCI device to the virtual machine (actually two devices since it is a dual scsi card.)
I had virtualized a single-drive tape drives with Vmware in the past.
However, when I tried I virtualize tape drive and loader, Solaris complained about the scsi id’s being invalid. I don’t think it likes two devices with a single scsi ID. Also, I think I need the backup software to see the REAL tape drive and autoloader (for inventory, changing tapes etc)
On the Solaris 10 U9 “Test” machine:

Any ideas? Maybe a need to update the MPT driver or is that dangerous?
Thanks

Actually, updating the kernel patches (and enabling hot plug service) did solve the problem. At some point during between testing the system before and after patching, the tape drive got turned off. Since the system patching was being done remotely it was not immediately obvious that the tape drive was off.

MS SQL 2005 not recognize the tape drive?

I have a SQL 2005 Server (SP1) running on Windows 2003 server machine. Now windows can detect the tape drive attached to the system as 'HP StorageWorks DLT VS160'. Even 'ntbackup' detects it and is able to backup data to the tape drive. However, SQL Server is unable to detect the tape drive. The tape does not show up in the Backup Devices in Server Objects and hence I'm unable to take backups directly to the tape via SQL Server. How do I get SQL 2005 to recognize the tape drive?

Hi,
I dont know if you trying to install new tape drive or old.
If its new, thn after installing Tape driver restart your server(tape should be online with correct light indication).
Then goto mycomputer->properties and under removable drives it should show your tape drives with name.
Second you can download the campatible HP tool from HP website, install and run.
It will tell you almost everything about your drives and you can upgrade tape firmware too.
Make sure you stop SAP service before running HP tool as it may restart your server too with blue screen or dump.
So be very sure about compatibility of the tool.
Regards
Mani
