Mounting an iSCSI Share in Windows

Follow

 

Scope

This article explains how to mount a Datto iSCSI share in Windows.  The iSCSI share can be a production share, a mounted file restore on either a SIRIS or Datto NAS, or it may be cloud based ISCSI target created by Datto Support.

You can mount an iSCSI share with Mac and Linux or even use it as a datasource for a virtual machine. These instructions are an example of how to mount the share using Windows.

Procedure

There are two main parts to this procedure. First, find the iSCSI target address. Second, use the IP address for the Datto and the target address to mount the iSCSI share in Windows.

Obtaining the iSCSI Target

If you need to mount a cloud based ISCSI target, the necessary details will be provided by Datto Support.

For creating an ISCSI File Restore, please see this article: Creating an ISCSI File Restore

If you want to mount the iSCSI share from a Datto NAS or Siris, follow these steps:

1. Log in to the Remote Web interface for the Datto NAS.

2. Click on the File Share tab. Then, find the share that you want to connect to and copy the iSCSI target address to the clipboard:

Mounting the iSCSI Target in Windows

1. On the Windows machine, search for and launch iSCSI Initiator, as shown in Figure 2:

2. In the iSCSI Initiator, enter the IP address for the Datto NAS or Siris, or the IP of the offsite server for a cloud target, into the Target field, as shown in Figure 3. Then, click Quick Connect.

4. In the Quick Connect window, click on the target you want to connect to. Then, click Connect

If this ISCSI Target uses a password (such as a cloud based target created by Datto Support), or is an ISCSI File Restore where CHAP Authentication was enabled, you will receive an Authentication Failure message. To resolve this, click OK on the error. Click Connect again, then click Advanced...  In the new window, check the box for Enable CHAP log on, then fill out the two files as shown in Figure 5.

Name:
 Change this to be the IQN of the original ISCSI Share
Target secret: This should be the password provided by Datto Support or the one chosen when enabling CHAP Authentication on the File Restore. 

Click OK, then OK again on the window behind it. The Target should now show as Connected.

If this is a new share, you will need to initialize and format it for use in Windows the first time it is mounted. To do so, start the Disk Management program. You will see the Initialization window, as shown in Figure 6. Click OK.

Next, format the disk. Right click on the Disk volume for the share, and then choose a volume formatting option, as shown in Figure 7.

If the share is not showing in Explorer as an available drive, you may need to mark it as Online:  In Disk Management, as shown in Figure 7, right click the drive, and click the option for Online.

You can now access the iSCSI share as a drive in Explorer or This Computer.
