We highly recommend that after you set up your initiator you customize your iSCSI settings as
discussed in
Customizing Your Linux iSCSI Settings (p. 376)
.
Customizing iSCSI Settings
After setting up your initiator, we highly recommend that you customize your iSCSI settings to prevent
the initiator from disconnecting from targets.
By increasing the iSCSI timeout values as shown in the following steps, you make your application
better at dealing with write operations that take a long time and other transient issues such as network
interruptions.
Note
Before making changes to the registry, you should make a backup copy of the registry. For
information on making a backup copy and other best practices to follow when working with the

Customizing Your Windows iSCSI Settings
When using a Windows client, you use the Microsoft iSCSI initiator to connect to your gateway volume.
For instructions on how to connect to your volumes, see
Connecting Your Volumes to Your Client (p. 65)
For a tape gateway setup, connecting to your VTL devices by using a Microsoft iSCSI initiator is a two-
step process:
1. Connect your tape gateway devices to your Windows client.
2. If you are using a backup application, configure the application to use the devices.
The Getting Started example setup provides instructions for both these steps. It uses the Symantec
NetBackup backup application. For more information, see
Connecting Your VTL Devices (p. 84)
and
Configuring NetBackup Storage Devices (p. 122)
To customize your Windows iSCSI settings
1. Increase the maximum time for which requests are queued.
a. Start Registry Editor (
Regedit.exe
).
b. Navigate to the globally unique identifier (GUID) key for the device class that contains iSCSI
controller settings, shown following.
Warning
Make sure you are working in the
CurrentControlSet
subkey and not another control
set such as
ControlSet001
or
ControlSet002
