c. Instead of turning off the power to other supporting devices ( for example,
management stations, Fibre Channel switches, or Ethernet switches),
disconnect the communications cables to the supporting devices.
Monitoring status through software
To monitor FAStT900 Storage Server status, always run the storage-management
software and check it frequently. Be sure to enable the management alerts that you
need. The storage-management software provides the best way to diagnose and
repair FAStT900 Storage Server failures. This software can help you:
v Determine the nature of a failure
v
Locate a failed component
v Provide recovery procedures to repair a failure
Although the FAStT900 Storage Server has fault indicators, these lights are
summary indicators and might not identify the specific component that has failed or
needs replacing, or which type of recovery procedure you must perform. In some
cases (such as loss of redundancy in FAStT900 Storage Server drive loops), the
fault light does not come on. Only the storage-management software can detect the
failure.
Recovering from a FAStT900 Storage Server failure might require you to perform
procedures other than replacing the component. The storage-management software
gives these procedures when you are using the Recovery Guru menu.
Note: Always follow the software recovery procedures to prevent data loss.
For more information about the storage-management software, refer to the Online
help or publications that are appropriate for your operating system (see “About this
document” on page xvii for a list of publications).
Checking the indicator lights
The FAStT900 Storage Server indicator lights display the status of the FAStT900
Storage Server and its components. Green indicator lights mean normal operating
status; amber indicator lights mean a possible failure.
It is important that you check all the indicator lights on the front and back of the
FAStT900 Storage Server a few minutes
after you turn on the power. After you turn
on the power, the indicator lights might blink intermittently. Wait until the FAStT900
Storage Server completes its power up before checking for faults. It can take up to
15 minutes for the battery to complete its self-test and up to 24 hours to fully
charge, particularly after an unexpected power loss of more than a few minutes.
The indicator lights for the components of the FAStT900 Storage Server are
described in the following sections.
Storage server indicator lights
The storage server has five indicator lights, as shown in Figure 24 on page 21. To
view the storage server indicator lights, you do not have to remove the FAStT900
Storage Server bezel.
