4. Inventory Enclosures to Be Removed
4. Inventory Enclosures to Be Removed
Before you remove enclosures from your system, inventory each enclosure to identify
its devices, communication paths, and subsystems. Record this information on
Worksheet 8:
You now can see what devices exist in each enclosure. You can decide:
•
Whether to terminate or relocate system resources and user processes
•
Which devices to reconfigure on the donor system
•
Which devices to move to the target system
For example, if you are removing an enclosure that contains an E4SA, GESA, or
G4SA, you know that you might need to move or terminate all TCP/IP connections and
any processes started from these sessions.
Step Action Result
1. In the tree pane in the OSM Service
Connection or TSM Service Application,
expand the icon of the highest-numbered
enclosure you will remove.
The tree pane displays the devices in
the enclosure.
2. In the tree pane, fully expand the
enclosure. For IOAM enclosures, fully
expand each module.
The tree pane displays all names of all
devices in the enclosure.
3. Referring to the slot numbers on Worksheet 8, determine the names and types of
the associated devices, as follows: Right-click each device listed in the tree pane
and fill in the name and type (for example disk, SEB, E4SA) of each device on
Worksheet 8.
Do the same for each IOAM enclosure, except use Worksheet 8a.
Click Close.
4. Bring Worksheet 8 to the service side of the enclosure. Check the SCSI connectors
on the PMF CRUs or IOMF CRUs in slots 50 and 55. If any tape drives are attached
to these connectors, add that information to the worksheet.
5. Repeat these steps for all other enclosures you plan to remove. Use a separate
copy of the worksheet for each enclosure.
