I have honestly never experienced any problems with Symantec drivers on 32-bit Windows servers. This is what the Device Compatibility Guide says w.r.t. tape drivers: 4. For 32-bit Windows systems, Symantec tests and recommends the use of the Symantec tape drivers. The latest release of the Symantec Tape Device Driver Installer can be downloaded from the Symantec support site. Symantec does not extensively test with the manufacturers' 32-bit tape drivers, however, they are supported, and Symantec will work with customers and vendors in an attempt to resolve any issues. Symantec and most hardware vendors listed are members of TSANet. 5. For 64-bit Windows systems, the manufacturer's most recent tape driver should be used. The Symantec tape drivers are not compatible with 64-bit Windows systems. Also see the following section in the Compatibility Guide w.r.t. IBM Tape Driver: IBM Tape Driver Support The list below is intended to show the latest versions of the IBM device drivers that have been tested with NetBackup.

This option permits a tape drive to be accessed by multiple processes on a Media Server, which is a requirement for NetBackup. NetBackup requires the IBM Data Path Failover feature to be disabled on the IBM tape device driver. To disable this feature, open the reg folder of the IBM driver package, double-click DisableDPF.reg, and reboot the system. - IBMTape driver level 6.1.9.5 tested on Windows Note: The "ULTRIUM-TD" and the "ULT3580-TD" inquiry strings are interchangeable (both are supported), unless otherwise indicated.

What happens when you run the Configure Storage Devices wizard from the NBU console?

No drives are detected if I run the Storage Devices Wizard. The problem seems to be on the LTO drivers but I don't understand where exactly... The Scan command is just an scsi command ? So why that does not detect any drives ?

Have you stopped and disabled RSM? Have you installed/checked NBU Device Mappings? Have you crossed out the drive serial numbers in the output above or do they really show up as 'xx'?

It's been a while since I implemented my NetBackup system but I did have a driver problem along the way. My tape drives are Quantum. If I used the drivers supplied by NetBackup my drives would not work. I had to download drivers from the Quantum website. Maybe this helps.

Hi Frigo, As Marianne mentioned, please check your NBU Device Mappings. Run this command from your Windows Media server: C:\Program Files\VERITAS\Volmgr\bin\tpext -get_dev_mappings_ver You should get the response like below device mappings version in the EMM database is 1.78 device mappings version from the local file is 1.78 Local device mappings file is up-to-date If it says the local device mapping file is out ot date, run this command to sync it with the NBU Master server: C:\Program Files\VERITAS\Volmgr\bin\tpext -get_dev_mappings See this link about the device mapping file on Windows (http://www.symantec.com/business/support/index?page=content&id=HOWTO33875#id-SF780390819) NetBackup uses a file to determine which protocols and settings to use to communicate with storage devices. NetBackup also uses the file during device discovery and configuration.

Tape drives are not discovered by Netbackup

Hello All,

We have a problem on NetBackup 6.5.5 on our Windows 2003 Media Server.

On the windows device manager all LTO3 drives are perfectly discovered but NetBackup doen't see them (the scan command doesn't show anything) :

I've found some technotes about a similar problem but that doesn't work :

I've tested veritas drivers and the latest IBM drivers (6.2.x)

IBM Tape Diagnostic Tools show drives perfectly :

Hi Frigo,

As Marianne mentioned, please check your NBU Device Mappings.

Run this command from your Windows Media server:

C:\Program Files\VERITAS\Volmgr\bin\tpext -get_dev_mappings_ver

You should get the response like below

device mappings version in the EMM database is 1.78
device mappings version from the local file is 1.78
Local device mappings file is up-to-date

If it says the local device mapping file is out ot date, run this command to sync it with the NBU Master server:

C:\Program Files\VERITAS\Volmgr\bin\tpext -get_dev_mappings

See this link about the device mapping file on Windows (http://www.symantec.com/business/support/index?page=content&id=HOWTO33875#id-SF780390819)

NetBackup uses a file to determine which protocols and settings to use to communicate with storage devices. NetBackup also uses the file during device discovery and configuration.

I have test by disabling RSM but that does not correct the problem but I didn't test the NBU device mappings.

I will test the tpext command tomorrow (I'm in France, it's time to sleep here :D), thanks CY for detail.

I'll give you a feed back as soon as possible.

Hi again,

I've verified device mapping version and it's OK :

C:\Documents and Settings\admins>"D:\Program Files\VERITAS\Volmgr\bin\tpext" -ge
t_dev_mappings_ver
device mappings version in the EMM database is 1.78
device mappings version from the local file is 1.78
Local device mappings file is up-to-date

If you have any other idea.. :/

I will assume 32 bits as you mention tested both IBM and "Symantec-Tapedrivers".

I have seen some IBM drives/firmware's that requires the IBM-Tapdevice drivers to work proper.

Some IBM-drivers can be installed as install_exclusive or non-exclusive. Both installscripts can be present in the driver package. You need to use the "install_exclusive.exe" script for NetBackup.

PS! - I have seen some driver packages out there that did confused this terms!

I have used and prefer the IBM driver 6.2.0.7 version for 2008 and 2003 both 32 and 64bit.

Please verify which IBM tape driver package you used. See below -

IBMTape.x86_6nnn.zip   - used for Windows 2003, running on x86
IBMTape.x64_6nnn.zip   - used for Windows 2003, running on AMD64 and EM64T
IBMTape.x86_w08_6nnn.zip   - used for Windows 2008, running on x86
IBMTape.x64_w08_6nnn.zip   - used for Windows 2008, running on AMD64 and EM64T

Like Even said, I guess you used IBMTape.x86_62nn.zip?

Not too sure about windows but for AIX one needs to install atape drivers for for version 6.5.2 and above
