MSL2024 Tape Library

Hi all;

Someone of you know how I can make that a server with Windows2003 can recognize MSL2024 tape library? I installed HP SW Library and Tape Tools(ver 4.1) but when I made a scan, it shows me the library like a HP Ultrium 2 SCSI device not like a library.
The server show me Device Manager section the library like HP Ultrium 2-SCSI SCSI Sequential Device too.

Please see the attached file.

Any idea??

I really appreciate your help.
Thanks a lot!

Re: MSL2024 Tape Library

You should see two devices, HP Ultrium 2 SCSI, and MSL G3 Series Medium Changer.

When the medium changer does not show up it usually means that the HBA does not support LUN mode or does not have LUN scanning enabled in the Bios.

First check to make certain that you are not connected to an array controller. Array controllers almost never support LUN mode devices and have very poor if any support for tape drives.

If you are connected to a standard HBA check the bios settings for the HBA and make certain that LUN scanning is enabled.

Re: MSL2024 Tape Library

Hi all;

Curtis, I have a doubt, If the library is connected by SCSI port how I can define if LUN scanning is enabled, is it on FC card?

My server has a Emulex FC card and it shows me LUN 0 in mapping section, for this reason I think that I need to change the Drive and Robotic LUN's of the library but I can understand how, please let me know your comments.

The file that I thought was attached showed how my server recognize the library, well only the SCSI 2 Ultrium Drive.

Thanks a lot,

Re: MSL2024 Tape Library

The MSL 2024/4048 series libraries are LUN devices as mentioned.

I believe LUN must be enabled on a FC card. Reasones why LUN might not be enabled: card does not support LUN (RAID card), LUN might need to be enabled manually throught he bios of the card.

You should not change the LUN numbers on devices they will automatically default to different numbers (either 0 or 1). There is no need to change these numbers.

If it is not being detected it is 99% of the time not a hardware issue, it is a hardware conflict or software problem.

Re: MSL2024 Tape Library

In addition Device Manager will show a tape drive and an entry under 'unknown medium changer'... this is usually because drivers are not installed on the tape library yet.

Check to see if there is an entry under device amanger for 'unknown devices' this is also related to uninstalled drivers.

Re: MSL2024 Tape Library

I tried to enable LUN scanning from BIOS but not options are showed for this.

Please help me showing the attached file, maybe it can give you more details about my issue :(

Re: MSL2024 Tape Library

Are you connecting a fibre channel MSL 2024? You message says that the host detected an "Ultrium 2-SCSI" tape drive. If the the drive is an Ultrium 2 then the library has to be parallel SCSI. Fibre Channel is only available with the Ultrium-3 drive in the MSL 2024.

For a parallel SCSI library you need to check the bios of your parallel SCSI HBA not the bios of the fibre channel HBA.

With a quick scan of the HBAnyware documentation it looks like that utility is only for SAN connect devices and will not show parallel SCSI devices so it might not show your library or drive.

In the L&TT screen shot neither the library or the drive were found by L&TT. That can mean that RSM (or another application) is running and has grabbed and locked the tape drive or the tape drive is not connected. It sounds like you are using DP so RSM should not be running and the drive should be accessible to L&TT.

Re: MSL2024 Tape Library

Hi all!!

Curtis; as you say we connected the MSL2024 library with a parallel SCSI cable, we had DP running in our server but is was disabled, however L&TT does not detect the library.
The manual tell us that we need a Ultra 160 SCSI LVD/SE HBA in our server, but when we access to the BIOS we can not see anything that tell us the model, how we could find it and how could enable the LUN scanning in the SCSI HBA?

On the other hand, please see the attached file that show in command view that the SCSI ID of the drive is 4 but L&TT show it the value 5 and if I change the SCSI ID of the drive L&TT show me 5 all time; is it correct??

I really appreciate your help.
Please let me know your comments.

Thanks a lot,

Re: MSL2024 Tape Library

What's your currnt BIOS firmware version? What's the make and model of you're motherboard?
Same question for the server model.

This appears to be a HW compatibilty issues so lets focus on that for the time being before moving up to the 2003 O/S.

Re: MSL2024 Tape Library

I can't explain why L&TT reports a SCSI ID of 5 when the library says it is set to 4. I'll look into that issue and see if there is a known case where this can occur.

Can you please use L&TT to pull a support ticket from the drive and post it here zipped? That may have some tips that will help explain the ID's.

As another poster has already said we need more details about the computer and HBA you are using to provide any tips on verifying LUN scanning.

Re: MSL2024 Tape Library

We have a Proliant DL380 G2 server with Windows 2003 Ent Ed. SP1, firmware version is:

BIOS (P24) Ver: 2002.08.17
Smart Array 5i & SA-532 Ver: 1.92
BD00912578 & BD01812579 drivers Ver: BCJE

I attach the ticket of the Drive.

Thanks a lot!

Re: MSL2024 Tape Library

I haven't completed review of the support ticket but one item jumps right out.

The drive is attached to a SmartArray controller. The SmartArray and most other array controllers do not support LUN mode and can't be used with an MSL2024.

In general use of an array controller with a tape device is not recommended.

If you are referring to the L&TT files he attached the format is correct for viewing with L&TT http://www.hp.com/support/tapetools which uses a header (.ltt) and data (.dat) files.

Re: MSL2024 Tape Library

Hi all!

I am so confused I can not understand so well the Smart Array concept because if I am right all Proliant servers works with this concept for their internal disks and if MSL2024 can not work with Smart arrays what kind of servers I can use :( ?

Thanks in advance,

Re: MSL2024 Tape Library

Many Proliant servers have built in SmartArray controllers. Those are SCSI arrary controllers and not general purpose SCSI controllers. The connectors look just like standard SCSI controllers and they use SCSI commands but the array controllers do not support the full SCSI specification and can not be used to connect an MSL 2024. An MSL 2024 may be connected to a system with a SmartArray controller but can not be connected to the SmartArray controller.

The MSL 2024 must be connected to a general purpose SCSI controller.

According to the L&TT support ticket the installed SCSI drivers are:
HP Autopath driver
HP/Compaq SmartArray Controller
Emulex Light Pulse MiniPort

None of those will support a parallel SCSI MSL2024 tape libary. The library is currently connected to a SmartArray controller which can communicate with a tape drive but can not communicate with the tape library.

The EBS matrix at http://www.hp.com/go/ebs on page 30 lists the approved HP HBA's for parallel SCSI products and the ones recommended for an LTO-2 MSL 2024 connected to a Windows server are:
268351-B21 Ultra320, LVD, Dual Channel, VHDCI
374654-B21 Ultra320, LVD, Single Channel, VHDCI
284688-B21 Ultra160, LVD, Dual Channel, VHDCI
C7474A Ultra160, LVD, Single Channel, VHDCI

Page 32 lists the 3rd party HBA's that are supported.

Re: MSL2024 Tape Library

I think I have found the answer to the SCSI ID disagreement between L&TT and the library.

The array controller has a Compaq Logical Volume listed at address 4 so that address is not available for the library. I suspect that the array controller automatically created a virtual device when it saw a device connected at ID 4 but it made the raw device available at ID 5.

The array controller makes the drive available to the OS at SCSI ID 5 even though it actually is configured to use ID 4. The drive is configured correctly.

Re: MSL2024 Tape Library

Hi.

We change the card by model U160/LVD and by U320 SCSI LVP/SE, we restart the server and MSL2024 library and L&TT not recognize the library.

I really appreciate your help.
Thanks a lot!

Re: MSL2024 Tape Library

Please provide additional information.

Are you saying that you installed a supported HBA?

With the library connected to the new HBA is anything found during boot?

Which HBA are you using?

Which driver version?

How is the library connected to the HBA? Cable length, how many devices, were is the termination?

Please attach an L&TT support ticket with the library connected to the new HBA if you are having problems communicating with the library.

Re: MSL2024 Tape Library

Tape units are never recommended to be connected to onboard or RAID cards (like smart array)


You are using a DL 380 G@, which is an old server. I would be concerned about througput issues for the LTO drive(s).

You need to install a PCI non-raid HBA card to get LUN working
As per HP Compatibility page you need one of these PCI cards for your library. They will recognize LUN's:
http://www.hp.com/products1/storage/compatibility/tapebackup/ISS/Detail/16-0029-0012.html

EXCERPT FROM ABOVE LINK:
The HP ProLiant DL380 G3 (Retired) does not have a suitable embedded SCSI controller.Please use one of the following adapters:

374654-B21 - Single channel Ultra320 SCSI HBA G2
268351-B21 - Dual channel Ultra320 SCSI HBA (Retired)
284688-B21 - Dual channel Ultra3 SCSI HBA* (Retired)

* Please ensure the adpu160m.sys driver Version 6.1.640.100 or higher (available from www.compaq.com/support) is used in this configuration.

PLEASE ALSO NOTE this is for a G3 not a G2... which means that HP has not tested the compatibility with a LTO 448 drive with a G2 DL380 server and you may not get it to work correctly. My main concern for this is that throughput will be limited and thusly cause shoeshining on your drive and premature wear or both drive and media.

LTO's need high Performance from servers. Please download and run the PAT tool here to assess your system that it can achieve the minimum spec of the LTO drive (24mb/s native)

Re: MSL2024 Tape Library

On another note... the MSL 2024/4048 have only been out for 6 months and your server is not even listed as retired anymore because it is a G2... the oldest DL380 server HP has listed is a G3.

Is your Library sharing a SCSI ID of another product on the Bus? All tape units should be isolated on the bus.

Does POST see the library and drive connected to the Ultra 160 or Ultra 320?

Make sure you are using an HBA driver not a RAID driver or you will still have LUN detection issues.

Make sure the PCI card is in the correct slot, some slots are 33 mhz and some are 66mhz on Proliant servers.
Your server should be upgraded to the latest support pack for the Proliant... available from
http://www.compaq.com

I still recommend using one of the cards I listed in my previous post for full compatibility with a proliant server.

Detection issues on POST will help us determine where the detection issue lies... there are only so many things that it could be if it is not seen on POST correctly, whereas if it is only not seen correctly when the OS loads then the possibilities for the detection causes are endless.

Re: MSL2024 Tape Library

hello!!

Can you see the attached file, we are using a DL380 G2, the card is model U320 SCSI LVP/SE, and the PCI card this in the correct slot, the library is not sharing a SCSI ID of another product on the Bus.


Thanks for your help
