To Detach A Board By Using Dr(1M) - Sun Microsystems Sun Enterprise 10000 Dynamic Reconfiguration User Manual

9. Select the complete button.
This operation may take several minutes to complete, particularly if an operating
environment quiescence is necessary. When it is finished, the board devices are
detached from the operating system.
If your attempt to complete the detach fails, it may be due to any of the following
reasons:
All online processors in the domain are on the board being detached.
The board you want to detach contains the last processor in the "default"
processor set. You must add an additional processor from another system board
before you retry the Detach operation.
Primary network interfaces are on the board being detached. You must stop all
usage of these networks manually (see "Complete Detach" on page 27).
All usage of the I/O devices on the board you want to detach has not been
stopped. The Information pane identifies the device on which the error was
encountered (see "Complete Detach" on page 27).
The operating environment quiescence failed. You must determine and resolve
the cause of the error (see "System Quiescence Operation" on page 11).
After you have resolved the reason for the failure, you can select either complete
or force to complete the detach. If there are no further problems, the board is
detached and reset. When the board is successfully detached, the following
message is displayed:
Board detachment completed successfully.
Caution – Before you choose the reconfig button, you should read "Reconfiguration
After a DR Operation" on page 7.
You can now either reconfigure the device directories or dismiss the Detach window.
The board can be powered off and removed by hot-swapping, or it can be attached
to another domain, left in the system unattached, or reattached at a later time.

To Detach a Board By Using dr(1M)

Before you execute the following steps, read "Detaching a System Board" on page
26. The process of detaching a board is very similar with either Hostview or dr(1M).
The basic concepts are not repeated in this section. The dr(1M) program was
introduced in Chapter 1.
1. Set SUNW_HOSTNAME to the appropriate domain using the domain_switch(1M)
command.
