13.2.2 Understanding the system state using the expansion enclosure LEDs
The LEDs provide a general idea of the expansion canister status. You can obtain more detail
from the management GUI and the Service Assistant. Examine the LEDs when you are not
able to access the management GUI or the service assistant, or when the system is not
showing any information about a device.
The CMM also shows status information about your expansion canisters, which you can use
when the management GUI or the service assistant cannot be accessed. The CMM indicates
the current status of many of the LEDs on your IBM Flex System V7000.
The procedure shows the status for the expansion canisters. It does not show the status for
the drives.
IBM Flex System V7000 expansion enclosure includes two expansion canisters that are
located in the rear of the expansion enclosure. The expansion canister has no controls and
does not include battery unit. Figure 13-3 and Table 13-7 show expansion canister LEDs you
can use to determine the system state and appropriate actions to take to resolve the issues.
