on systems attached to an hmc, when the system attention led turns on, you should refer to the service action event log in the service focal point application on the hmc and check the open service events using the procedure described in working with serviceable events in the ibm hardware management console for pseries installation and operations guide.

    for information on service focal point settings, refer to setting up surveillance and enabling surveillance notifications in the ibm hardware management console for pseries installation and operations guide.

    events requiring customer intervention are marked as call home candidate? no. for all of these events, examine the description in the serviceable event error details. if actions are listed in the description, perform those actions. if the error indicates a loss of surveillance between the hmc and a partition, check the status of the partition, the network, and the cabling between the hmc and the partition. if the surveillance error persists, call service support.

    whether a user intervention error or an ibm serviceable error is detected, the system attention light can be reset by following the procedures in “resetting the system attention led”. the preferred method to reset the attention indicator is by following the hmc attached systems procedures. either the hmc attached systems procedures or the alternate procedures will reset the attention indicator.
