Specifying Flex Client properties

To specify properties for a client configuration, perform the following steps:

In the left pane of the Double-Take Flex Management Console, right-click the client that you want to configure and select Properties.

On the General tab, specify the following properties.

Property	Description
Enable this client	Select this checkbox to enable the client. If the client is in a group (see Working with Flex Client groups) then this checkbox must be selected for both the client and the group to be enabled.
Use this client for administrator console	If you are using the Double-Take Flex Storage Server shared non-persistent mode or WRITE redirection to local cache options with the discard_hdd_cache option set to Yes, and want to use this client to update the master image with updates that require system reboot (like Windows service pack update), select this checkbox. If this option is not selected, the reboot will cause the write cache on the Double-Take Flex Storage Server or on the local HDD to be discarded and you won't be able to do the update without changing the target's share settings.
Name	Specify a descriptive name for the Flex Client. This name is displayed in the left pane of the Double-Take Flex Management Console. Valid values: Maximum of 15 alphanumeric characters including hyphens; no special characters.
MAC address	Specify the MAC address of the Double-Take Flex Client. Do not include hyphens. The MAC address is a 12-digit hexadecimal identifier that is unique to every network adapter or NIC. You can use the following methods to find the MAC address: On the Flex Client, run the command ipconfig /all. The MAC address is displayed. Boot the Flex Client. The MAC address is displayed during the boot process. Use the Browse button to select from a list of MAC addresses that have made PXE requests (broadcasts) within the last seven days. Specify a wildcarded MAC address. Question marks (?) can be used as wildcard placeholders for Double-Take Flex Client that share similar models of NICs from the same vendor. The first six characters of the 12-digit MAC address always identify the manufacturer of the NIC. Therefore, you could use the first six characters of the MAC address and six question marks (?) as wildcards to complete the 12-digit MAC address. If any of the other digits were common to all MAC addresses in a group of client systems, you could use wildcards to represent those digits.
Description	(optional) Specify a description for the Double-Take Flex Client configuration.
Initiator name	Specify the iSCSI initiator node name that will be passed to the Double-Take Flex Client. The initiator name is used in the following order. If the initiator name is specified for an iSCSI target, that initiator name will be used by the Double-Take Flex Client. If the initiator name is not specified for an iSCSI target, and is specified for the client, that initiator name will be used by the Double-Take Flex Client. If the initiator name is not specified for an iSCSI target or the client, the Double-Take Flex bootstrap will create an initiator node name for the Double-Take Flex Client based on the client's MAC address.

On the Advanced tab, select any of the following properties. The PXE boot menu and Require user login and use the login user's boot settings properties are mutually exclusive.

Property	Description
Disable gateway on iSCSI boot disk (Windows Vista/2008/Win7 only)	Select this checkbox to enable a workaround for a Vista, Windows 2008, and Win7 iSCSI boot gateway issue. This option is recommended if you are experiencing slow performance in booting or direct-to-iSCSI installation and the Flex Client and target are in the same IP segment. Make sure this checkbox is deselected if the Flex Client and target are in different IP segments.
UNDI safe mode	Select this checkbox to enable safe mode. If you experience Windows hanging or a bluescreen prior to a login prompt when booting from the iSCSI disk, you may want to enable UNDI safe mode. One of the possible reasons for this is that the active UNDI NIC is affecting the Windows startup procedure. Once this setting is enabled, the Double-Take Flex bootstrap will make sure the UNDI NIC is closed before returning to NTLDR so that the Windows startup procedure is not affected by the active UNDI NIC.
PXE boot menu	Select this checkbox to display PXE boot or local boot agent menu choices, such as direct-to-iSCSI OS installation and the Client Deployment Tool options, during boot. If this option is selected, the client automatically boots without user authentication.
Require user login and use the login user's boot settings	Select this checkbox to control access to this client by requiring Active Directory login credentials.
Force reboot when user logs off	This option is available only when the Require user login and use the login user's boot settings checkbox is selected. Select this checkbox to force a reboot when a user logs off. This prevents anyone else (other than the original assigned user) that might log on from accessing/modifying the boot image that belongs to the original assigned user, and ensures that the next user to log on will have access to the boot image that is associated with their own user-specific boot volume.

On the Data Path tab, you can enable a data path target and specify related parameters. (If a client is in a group or is later added to a group, the data path is honored.)

Property	Description
Enable Data Path iSCSI Target	Select this checkbox to store data on a separate target.
Target	Click Change to select a target for the data. Do not select a target that is being used as a boot volume. You must also be aware if the target that you select has already been selected as the data path target for a different client.
Drive	Select the drive letter that you want to represent the data path target on the client. Whenever the client boots, user data will be accessible from and saved to this drive.
Portal	These fields are automatically populated when a target is selected.
