STARTED. Do not proceed with system reduction until all devices in the enclosure
you are removing are listed as STOPPED.
Repeat this procedure to stop internal disk drives for each internal disk drive in
each enclosure to be removed.
Delete Internal Disk Drives
Use the SCF DELETE DISK command to delete internal disks from the system
configuration:
From the OSM Service Connection or TSM Service Application tree pane, every
internal disk you deleted should be listed as an Unknown Disk CRU.
Prepare and Stop Adapters
In Step 4. Inventory Enclosures to Be Removed on page 4-7, you recorded the names
of all adapters in all the enclosures you are removing from your system on one copy of
Worksheet 8 for each enclosure. Now examine those worksheets to determine how
removal of an enclosure will affect the operations of your system.
In general, you are answering the following questions:
•
What subsystem is used to control each adapter?
•
What subsystem entities are subordinate to each adapter?
•
What clients use those entities?
You will stop all adapters in each enclosure you will remove.
Procedures for stopping any device or subsystem are specific to that device or
subsystem. For information about how to stop devices or subsystems, see the
appropriate manual. In some cases, a process running in an enclosure that will not be
removed might use hardware in an enclosure that will be removed.
In general, you will perform the following tasks within each subsystem:
1. Identify the subsystems that use adapters.
2. In each enclosure to be removed, stop as many I/O processes as you can.
3. Use subsystem-specific commands to stop the devices controlled by any I/O
processes within that subsystem.
