Specifying Flex Target properties

To configure the properties for a Flex Target, perform the following steps:

In the right pane of the Double-Take Flex Storage Console, right-click the desired Flex Target and select Properties.

On the General tab, specify the following properties.

Property	Description
Target name	The Flex Target name can be changed here. The default iSCSI Flex Target name prefix is a global option. In the preceding example, the default option is `iqn.2006-01.com.doubletake.flex:rep1`. To modify the default option, see Defining global options.
Disk file	Use the Change button to point to a different disk file. UNC path values are supported, for example: \\`ComputerName`\`SharedFolder`\`Resource.vhd` The `ComputerName` may be an IP address or host name.
Disk mode	Select a disk mode for the Flex Target. Note: Before a disk can be set to either of the shared modes, it must be initialized, partitioned and formatted under exclusive mode and contain the basic data intended for usage prior to sharing. For detailed explanations about the disk modes, see the following sections: Exclusive mode Shared-persistent mode Shared-nonpersistent mode Concurrent mode
Disk size	This is a read-only area that shows the current size, maximum size and amount of free space on the default drive used for storing target disk files. Current size and Maximum size may differ if all disk space was not allocated at time of disk creation.
Description	(optional) Specify a description for the Flex Target.

On the Authentication tab, you can enable CHAP authentication and specify the user name and password.

Field	Description
Enable CHAP authentication	Select this checkbox to enable CHAP authentication.
User name	Specify the CHAP user name that corresponds to the Double-Take Flex Client that will boot from this Flex Target.
Password	Specify the CHAP password that corresponds to the Double-Take Flex Client that will boot from this Flex Target.

On the Access Control tab, you can enable or disable access control. You can add multiple entries (to allow multiple client access) to a single target disk.

Note:

If Access Control is enabled on a target with an empty Allowed IQN/IP list, no iSCSI initiator will be able to login to the target. That will effectively disable the target without removing it from Flex Storage server.

To add an access control entry, select the Enable access control checkbox, then click Add. The Edit Access Control Entry dialog box will appear.

In the Type field, select the type of identifier to use to limit access:

IQN—The iSCSI Qualified Name of the iSCSI Initiator (the iSCSI ‘client’ piece of the Flex client) that would attach to this iSCSI target.

IP address—The IP address of the NIC on the Flex client system that would attach to this iSCSI target. Value would an IP address.

In the Value field, enter the IP address or IQN identifier.

If you selected the IQN type, you can click Browse to browse for any iSCSI initiators that have recently attached or logged in to the Flex Storage Server.

Note:

When adding IP addresses to the allowed list, wildcards can be used to specify a range of IP addresses without entering them one by one. For example, 192.168.20.* can be entered as an allowed IP address which enables all initiators on the IP segment 192.168.20.0 to access the target.

Wildcards are not allowed for IQN identifiers.
