Using The Cmm For Troubleshooting Tasks - IBM V7000 Introduction And Implementation Manual

13.8.1 Using the CMM for troubleshooting tasks

The CMM manages individual nodes within the Flex chassis. For IBM Flex System V7000
Storage Node, the CMM manages each canister within an enclosure individually.
If you use the CMM to manage the IBM Flex System V7000, be aware of inter-dependencies
between all canisters in all the enclosures in the system, and do not perform operations that
might cause the system as a whole to stop providing access to data. It is always preferable to
use the IBM Flex System V7000 management GUI to manage the system that is available.
You should only use the CMM when directed to do so by service actions.
To view IBM Flex System V7000 Storage Node information using the CMM, use the following
steps:
1. Open the CMM and navigate to the Chassis Map. The Chassis Map provides a front and
rear graphical view of the Flex chassis components. The front view shows compute nodes
and storage control enclosures, including canisters and drives. The rear view shows
power modules, cooling devices, fan-mux, I/O module, and Management module.
The front view of the Chassis Map also shows the bay numbering scheme. Generally, bay
numbers increment across each row (left to right) from the bottom left to the top. A storage
control enclosure takes up four bays. Each canister within a storage control enclosure
takes up a bay. Canisters have a slot designation that appears when you hover over them.
For example, starting at the bottom left, drives in the first enclosure take up bays 1 through
4. The left canister is in bay 1. The right canister is in bay 2. Moving up, the next enclosure
takes up bays 5-8. The left canister is in bay 5, and the right canister is in bay 6. The bay
numbering scheme continues in the same manner as you move up.
2. Look for colors as an indication of an IBM Flex System V7000 canister's status, as shown
in Table 13-12 and Figure 13-25.
