Processes - Sun Microsystems Sun Enterprise 10000 Dynamic Reconfiguration User Manual

1. If the redundancy features of Alternate Pathing or Solstice DiskSuite mirroring
are used to access a device connected to the board, reconfigure these subsystems
so that the device or network is accessible using controllers on other system
boards. Note that for Alternate Pathing 2.1, the system automatically switches the
disk devices to an alternate interface if one is available.
2. Unmount file systems, including Solstice DiskSuite metadevices that have a
board-resident partition (for example, umount /partit).
3. Remove Alternate Pathing or Solstice DiskSuite databases from board-resident
partitions. The location of Alternate Pathing or Solstice DiskSuite databases is
explicitly chosen by the user and can be changed.
4. Remove any private regions used by Sun Enterprise Volume Manager™ or Veritas
Volume Manager. Volume manager by default uses a private region on each
device that it controls, so such devices must be removed from volume manager
control before they can be detached.
5. Remove disk partitions from the swap configuration by using swap(1M).
6. Either kill any process that directly opens a device or raw partition, or direct it to
close the open device on the board.
7. If a detach-unsafe device is present on the board, close all instances of the device
and use modunload(1M) to unload the driver.
8. Kill all of the real-time processes that are open if the operating environment must
be suspended.
Caution – Unmounting shared file systems by using the share(1M) utility may
affect NFS client systems.

Processes

You must perform certain tasks for non-network devices. Although the following list
of tasks implies a sequence of order, strict adherance to the order is not necessary.
1. If the operating environment must be suspended, kill all of the real-time
processes that are open.
2. Kill any processes that are bound to on-board processors.
When a board is detached, all processes bound to its processors are automatically
unbound. You can use pbind(1M) to rebind them to other processors.
