# Connecting your VTL devices
Following, you can find instructions about how to connect your virtual tape library (VTL) devices to your Microsoft Windows or Red Hat Enterprise Linux (RHEL) client.

## Connecting to a Microsoft Windows Client
The following procedure shows a summary of the steps that you follow to connect to a Windows client.
**To connect your VTL devices to a Windows client**
1. Start `iscsicpl.exe`.
**Note**
You must have administrator rights on the client computer to run the iSCSI initiator.
1. Start the Microsoft iSCSI initiator service.
1. In the **iSCSI Initiator Properties** dialog box, choose the **Discovery** tab, and then choose **Discover Portal**.
1. Provide the IP address of your Tape Gateway for **IP address or DNS name**.
1. Choose the **Targets** tab, and then choose **Refresh**. All 10 tape drives and the medium changer appear in the **Discovered targets** box. The status for the targets is **Inactive**.
1. Choose the first device and connect it. You connect the devices one at a time.
1. Connect all of the targets.
On a Windows client, the driver provider for the tape drive must be Microsoft. Use the following procedure to verify the driver provider, and update the driver and provider if necessary:
**To verify and update the driver and provider**
1. On your Windows client, start Device Manager.
1. Expand **Tape drives**, open the context (right-click) menu for a tape drive, and choose **Properties**.
1. In the **Driver** tab of the **Device Properties** dialog box, verify **Driver Provider** is Microsoft.
1. If **Driver Provider** is not Microsoft, set the value as follows:
1. Choose **Update Driver**.
1. In the **Update Driver Software** dialog box, choose **Browse my computer for driver software**.
1. In the **Update Driver Software** dialog box, choose **Let me pick from a list of device drivers on my computer**.
1. Choose **LTO Tape drive** and choose **Next**.
1. Choose **Close** to close the **Update Driver Software** window, and verify that the **Driver Provider** value is now set to Microsoft.
1. Repeat the steps to update driver and provider for all the tape drives.
## Connecting to a Linux Client
The following procedure shows a summary of the steps that you follow to connect to an RHEL client.
**To connect a Linux client to VTL devices**
1. Install the `iscsi-initiator-utils` RPM package.
You can use the following command to install the package.
```
sudo yum install iscsi-initiator-utils
```
1. Make sure that the iSCSI daemon is running.
For RHEL 8 or 9, use the following command.
```
sudo service iscsid status
```
1. Discover the volume or VTL device targets defined for a gateway. Use the following discovery command.
```
sudo /sbin/iscsiadm --mode discovery --type sendtargets --portal [GATEWAY_IP]:3260
```
The output of the discovery command looks like the following example output.
For Volume Gateways: `[GATEWAY_IP]:3260, 1 iqn.1997-05.com.amazon:myvolume `
For Tape Gateways: `iqn.1997-05.com.amazon:[GATEWAY_IP]-tapedrive-01`
1. Connect to a target.
Be sure to specify the correct *[GATEWAY\$1IP]* and IQN in the connect command.
Use the following command.
```
sudo /sbin/iscsiadm --mode node --targetname iqn.1997-05.com.amazon:[ISCSI_TARGET_NAME] --portal [GATEWAY_IP]:3260,1 --login
```
1. Verify that the volume is attached to the client machine (the initiator). To do so, use the following command.
```
ls -l /dev/disk/by-path
```
The output of the command should look like the following example output.
`lrwxrwxrwx. 1 root root 9 Apr 16 19:31 ip-[GATEWAY_IP]:3260-iscsi-iqn.1997-05.com.amazon:myvolume-lun-0 -> ../../sda`
For Volume Gateways, we highly recommend that after you set up your initiator, you customize your iSCSI settings as discussed in [Customizing Your Linux iSCSI Settings](recommendediSCSISettings.md#CustomizeLinuxiSCSISettings).
Verify that the VTL device is attached to the client machine (the initiator). To do so, use the following command.
```
ls -l /dev/tape/by-path
```
The output of the command should look like the following example output.
```
