Use the StorSimple Manager service to manage access control records
Overview
Access control records (ACRs) allow you to specify which hosts can connect to a volume on the StorSimple device. ACRs are set to a specific volume and contain the iSCSI Qualified Names (IQNs) of the hosts. When a host tries to connect to a volume, the device checks the ACR associated with that volume for the IQN name and if there is a match, then the connection is established. The access control records in the Configuration section of your StorSimple Device Manager service blade display all the access control records with the corresponding IQNs of the hosts.
This tutorial explains the following common ACR-related tasks:
- Add an access control record
- Edit an access control record
- Delete an access control record
Important
- When assigning an ACR to a volume, take care that the volume is not concurrently accessed by more than one non-clustered host because this could corrupt the volume.
- When deleting an ACR from a volume, make sure that the corresponding host is not accessing the volume because the deletion could result in a read-write disruption.
Get the IQN
Perform the following steps to get the IQN of a Windows host that is running Windows Server 2012.
To get the IQN of a Windows host
Start the Microsoft iSCSI initiator on your Windows host. Click Start > Administrative Tools > iSCSI initiator.
In the iSCSI Initiator Properties window, on the Configuration tab, select and copy the string from the Initiator Name field.

Save this string.
Add an access control record
You use the Configuration section in the StorSimple Device Manager service blade to add ACRs. Typically, you will associate one ACR with one volume.
Perform the following steps to add an ACR.
To add an ACR
Go to your StorSimple Device Manager service, double-click the service name, and then within the Configuration section, click Access control records.
In the Access control records blade, click + Add ACR.

In the Add ACR blade, do the following steps:
Supply a name for your ACR.
Provide the IQN name of your Windows Server host under iSCSI Initiator Name (IQN).
Click Add to create the ACR.

The newly added ACR will display in the tabular listing of ACRs.

Edit an access control record
You use the Configuration section in the StorSimple Device Manager service blade to edit ACRs.
Note
It is recommended that you modify only those ACRs that are currently not in use. To edit an ACR associated with a volume that is currently in use, you must first take the volume offline.
Perform the following steps to edit an ACR.
To edit an access control record
Go to your StorSimple Device Manager service, double-click the service name, and then within the Configuration section, click Access control records.

In the tabular listing of the access control records, click and select the ACR that you wish to modify.

In the Edit access control record blade, provide a different IQN corresponding to another host.

Click Save. When prompted for confirmation, click Yes.

You are notified when the ACR is updated. The tabular listing also updates to reflect the change.
Delete an access control record
You use the Configuration section in the StorSimple Device Manager service blade to delete ACRs.
Note
You can delete only those ACRs that are currently not in use. To delete an ACR associated with a volume that is currently in use, you must first take the volume offline.
Perform the following steps to delete an access control record.
To delete an access control record
Go to your StorSimple Device Manager service, double-click the service name, and then within the Configuration section, click Access control records.

In the tabular listing of the access control records, click and select the ACR that you wish to delete.

Right-click to invoke the context menu and select Delete.

When prompted for confirmation, review the information and then click Delete.

You are notified when the deletion completes. The tabular listing is updated to reflect the deletion.
