EML 103e tape library - LTO3 drives and autochgr drivers for Solaris 10

We have an EML 103e library with LTO3 drives. The interface card ports (Host ports) of EML library have been zoned with the HBA ports on our new Solaris 10 server using Qlogic QLE2462 HBA card.
#uname -a
SunOS server1 5.10 Generic_138888-08 sun4u sparc SUNW,SPARC-Enterprise

But we are not able to see the tape drives and the auto changer.
Are there any drivers required for this to be supported ?
Presently we have the following
PKGINST: SUNWqlc

Re: EML 103e tape library - LTO3 drives and autochgr drivers for Solaris 10

I never worked with solaris so far, but I would assume it will work with generic drivers ... another point to check is the library itself. Depending on your configuration you need to "present" the library to hosts - you know this from arrays like EVA.

Hope this helps!

Have you referred the EBS design guide?

It's available at
http://bizsupport1.austin.hp.com/bc/docs/support/SupportManual/c00775232/c00775232.pdf

Information from Page 132 onwards will be relevant in this case.

Re: EML 103e tape library - LTO3 drives and autochgr drivers for Solaris 10

Thanks Torsten - You gave the exact clue.
Sameer - thanks for the document, tried disabling multipathing as per document suggestion but that did not work.

Following is the summary of what we tried and what worked.

We had to configure the Host Access (Secure Manager) through Command View TL to allow the HBAs of the Solaris hosts in order to see/detect the tape drives. Then running cfgadm -al on the Solaris boxes created the device files in /dev/rmt and again, verified through luxadm probe and then luxadm display

But even after doing all this we were not able to use the tape drives through Data Protector from the media agent installed on the Solaris 10 boxes.
We had installed the DP client (disk agent and media agent) on the Solaris server through the Data Protector GUI using the installation server (which happens to be the cell manager on HPUX 11.11)
We raised a call with HP and were informed to update the patches, which when we tried to install on the Solaris servers but it gave error saying the base package is not installed.
Found out the work around to install the patches - need to use the packet.Z file in the respective folder for the downloaded and uncompressed Core, disk agent and media agent patch. The directory location would be something like this root/opt/omni/databases/vendor/omnicf/sun/sparc/solaris-10/A.06.00/packet.Z
You need to uncompress the packet.Z file which then can be used with the pkgadd command to install the patch.
Another important thing is that for Solaris the device name for tape should be BSD style - e.g. /dev/rmt/0mbn

Thanks,
