To prevent problems before they occur, you can monitor and verify the system hardware and software periodically. Some of the following activities can be completed on a daily or weekly basis. Typically, you complete the following activities at least every six months.
Verify that the prerequisite conditions for the system environment are still met. In particular, verify that temperature and moisture limits are not exceeded, and that airflow and power requirements are still met.
Check the error and information LEDs on the system. A system attention light, an enclosure fault light, or a system information light indicates that a serviceable event occurred on the system.
In the management GUI, check the status indicators on the Dashboard. In particular, examine the System Health tiles section of the Dashboard. Each tile represents a type of component. Tiles with errors and warnings are displayed first.
In addition to the System Health tiles, you can monitor the performance statistics for processor (CPU) utilization, host and internal interfaces, volumes, and storage pools.
Check for updates to the system software, and update the software as needed.
Check that sufficient free physical space (physical_free_capacity) is available to meet demand until you plan to add more physical capacity.
Check that each storage pool does not share a resource provisioning group (shared_resources) with another storage pool. Check that each storage pool has enough free physical space (physical_free_capacity) to meet demand until you plan to add more physical capacity.
Check that each over-provisioned managed disk (over_provisioned) has enough free physical space (physical_free_capacity) to meet demand until you plan to add more physical capacity.
You can configure event notification emails to be sent to you or to IBM via a Simple Mail Transfer Protocol (SMTP) server connection. You can select to send errors, errors and warnings, or all events.
