Re: HP MLS4048 Medium Changer Drivers

Not even as an unknown device?
There is maybe a problem with the connection.

Almost all backup applications I know are using own drivers bundled in the application.

However, AFAIR there is a driver bundle if you search for the MSL on hp.com.

Hope this helps!

Ahem...

I, The Great GoofBall say; "Check your cabling, run LT&T tools to verify that it's reachable, and if not please tell us your setup in more details"

Re: HP MLS4048 Medium Changer Drivers

Stop any backup apps you have installed. Stop their services, too.
Then run the tool again.

Re: HP MLS4048 Medium Changer Drivers

As said, the drive is probably locked by another application.

Hope this helps!

What does the "by product" tab show? Do you see the library?

Hope this helps!

Re: HP MLS4048 Medium Changer Drivers

Its FC and installed the FC drivers but it then says SCSI.
There are two drives with 48 slots
The connection is via HP StorageWorks 41B - Host bus adapter-PCI Express low profile-4Gb Fibre Channel

Re: HP MLS4048 Medium Changer Drivers

Check (by serial#) if you see the upper or lower drive.

I assume you see the upper only. Maybe a connection or zoning problem.

Check from the switch too.


The lower drive is "sharing" the connection with the robotics.

Hope this helps!

Re: HP MLS4048 Medium Changer Drivers

Is it OK that it says SCSI when it is fibre channel?

Yes it is normal to say SCSI - it is a common misconception that SCSI means the old parallel SCSI however SCSI refers to the protocol, not the physical connection. All of the HP tape drives use the SCSI protocol whether it is connected over parallel SCSI, FC SCSI, or SAS (Serial Attached SCSI).

Re: HP MLS4048 Medium Changer Drivers

Ok i understand that. So what is the way forward? Am stuck and really need to get this going guys.

Re: HP MLS4048 Medium Changer Drivers

I can repeat the next step only:

Check (by serial#) if you see the upper or lower drive.

I assume you see the upper only. Maybe a connection or zoning problem.

Check from the switch too.


The lower drive is "sharing" the connection with the robotics.

Hope this helps!

Re: HP MLS4048 Medium Changer Drivers

Connect to the management web page of the library, note down the WWN and serial no. of the drives. Check the FC connection status.

Check the switch if both are logged in.
Check the zoning, if both ports are visible to the server.

Hope this helps!

Torsten.

Sorry for taking long to respond. Let me do that and will update u

Re: HP MLS4048 Medium Changer Drivers

I assume from your thread that you have a MSL4048 with two LTO 4 FC

This libray use present the Media Changer via one of the drive, that drive is called Master, and the SCSI ID of the drive will be LUN0 while at the same SCSI ID at LUN1 you will see the Robot (Media Changer)

first step is to connect to the remote interface of the MSL using a browser and check the status of each drives, if they are ready or not

Second step is to check on the remote interface what is teh status of the FC ports, on each drive, one port should be connected to the switch and should be online

Third step is to log on the swich and check if both drives are logged in correctly on the related FC PORT Switch

fourth, Check the zoning to see if it is correct

Fifth goes in your HBA, reset any persistent binding, and rediscover the devices.

Once the HBA show everyting, your os will be able to see them too.

Re: HP MLS4048 Medium Changer Drivers

i seem to be getting somewhere but i have this problem.

Re: HP MLS4048 Medium Changer Drivers

Also the LTO media Assessment tells me that there is no tape when there is an LTO3 Ultrium WORM 800GB. What could be the issue?
