When kernel memory is copied, the Solaris OS is temporarily suspended. Therefore, you must understand the effect of disconnecting the network connection with remote systems and other influences of the DR operation on job processes before determining system operations.
2.1.5Reservation of Domain Configuration Changes
Besides letting you add, delete, or move system boards dynamically, DR also lets you order such reconfiguration to take place the next time the affected domains are turned on or turned off, or the domain is rebooted. Use the addboard(8), deleteboard(8), or moveboard(8) command with the
■A hardware resource cannot be dynamically reconfigured by DR for business or operational reasons.
■Domain configuration settings should not be immediately changed.■You want to avoid changing the current domain configuration settings and change the configuration immediately after the domain is rebooted when necessary to delete a system board having a driver or PCI card that does not support DR.
■You want to assign a floating board to a specific domain beforehand to prevent the system board from being acquired by another domain.
For how to reserve domain changes, see Section 3.1.10, “Reserving a Domain Configuration Change” on page
2.2Conditions and Settings Using XSCF
This section describes the operating conditions required for XSCF to start DR operations and the settings that are established by XSCF.
2.2.1Conditions Using XSCF
The DR operation to add a system board cannot be executed when the system board has only been mounted. The DR operation is enabled by registering the system board in the DCL by using the XSCF shell or XSCF Web. You must confirm that the system board to be added is registered in the DCL before performing the DR
