Configuring for availability and recoverability

This section provides availability and recoverability considerations for attaching a
Windows Server 2003 host system to a storage unit.

Configuration considerations

This section describes configuration considerations when attaching a storage unit to
a Windows Server 2003 host system.
This section describes how to ensure the optimum ability to retrieve and recover
data when you attach a Windows Server 2003 host system to a storage unit. You
must set the timeout value that is associated with the supported host bus adapters
to 60 seconds. The setting is consistent with the configuration for FC-AL adapters
and disk subsystems when they are attached to Windows Server 2003 host system.
The host bus adapter uses the timeout parameter to bind its recovery actions and
responses to the disk subsystem. The value exists in different places in the system
configuration. You can retrieve and use it in different ways depending on the type of
host bus adapter. See "Setting the TimeOutValue registry for Windows Server 2003"
for instructions about how to modify the value safely in the Windows Server 2003
registry.
