Hello Experts,

I have a tape drive attached to an ESX host and it is currently showing under configuration > advanced settings. However when I go to storage adapter it is not listed there.
Is there any step that I am missing?
Thanks,

You can back up virtual machine data by running a backup server within a virtual
machine that is connected to a tape drive or other SCSI-based backup media attached
to the physical system.
When using this method, keep in mind the following:
* VMware supports attaching SCSI drives to the ESX Server using Adaptec SCSI
adapters. Using other adapters, such as LSI MPT-Fusion SCSI, is not supported.
* If you are using a tape drive library (versus using a stand-alone tape drive), the
library must be multitarget, and not multi-LUN.
* Set the tape drive’s virtual target ID in the virtual machine’s configuration to be the
same as the physical target ID.
For information on attaching a SCSI-based tape drive to your virtual machine, see Basic
System Administration.

I am using a stand-alone tape drive Dell PowerVault 110T LTO  . I can see the tape drive in the ESX host bios and also under the hardware configuration of the host . However when i go to storage adapters the device is not listed there

You will need to configure VMDirectPath for your Tape device in order to make it available to your virtual machine. Check http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1010789 to ascertain if your setup meets all the requirements for VMDirectPath I/O and some configuration instructions.

Good Luck

Ok, following the steps outlined by bgoering:

Unber Configuration > Advanced settings, I do see the tape drive > 06:04.0 | Adaptec ASC-29320LPE PCIe U320 (with a green icon)
However, when I go to the actual server, right click > Edit settings >Hardware >Add> the PCI device Adaptec ASC-29320LPE PCIe U320 is not listed there.
Is there any step that I am mising?

Yes - see http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1010789

If you met the pre-requisites (the hast has VT-d) you go through configuration - advanced on the host to select devices to enable for directpath

You right click on the "No devices" line and select edit, then can assign devices

I already enable the device for direct path but when I try to add it to the server, the device is not listed there.

Did you make sure IOMMU is enabled for your VM? And enable both the controller and Tape drive?
