NOTE: The SMC does not provide an option for enabling or disabling Partner Firmware Update for the partner controller. To enable or disable the setting, use the set advanced-settings command, and set the partner-firmware-upgrade parameter. See the CLI Reference Guide for more information about command parameter syntax. Also see Using the CLI on page 24. Using the CLI 1. Log-in to the command-line interface. 2. To verify that partner firmware upgrade is enabled, run the following command: show advanced-settings 3. If partner firmware upgrade is disabled, enable it by running the following command: set advanced-settings partner-firmware-upgrade enabled NOTE: See the Lenovo Storage CLI Reference Guide for additional information. Verifying component failure Select from the following methods to verify component failure: • Use the SMC to check the health icons/values of the system and its components to either ensure that everything is okay, or to drill down to a problem component. The SMC use health icons to show OK, Degraded, Fault, or Unknown status for the system and its components. If you discover a problem component, follow the actions in its Health Recommendations field to resolve the problem. • As an alternative to using the SMC, you can run the show system command in the CLI to view the health of the system and its components. If any component has a problem, the system health will be Degraded, Fault, or Unknown. If you discover a problem component, follow the actions in its Health Recommendations field to resolve the problem. • Monitor event notification - With event notification configured and enabled, use the SMC to view the event log, or use the CLI to run the show events detail command to see details for events. • Check Fault/Service Required LED (back of enclosure): Amber = Fault condition • Check that the CRU OK LED (back of enclosure) is off Stopping I/O When troubleshooting disk drive and connectivity faults, stop I/O to the affected disk groups from all hosts as a data protection precaution. As an additional data protection precaution, it is helpful to conduct regularly scheduled backups of your data. IMPORTANT: Stopping I/O to a disk group is a host-side task, and falls outside the scope of this document. When on-site, you can verify that there is no I/O activity by briefly monitoring the system LEDs; however, when accessing the storage system remotely, this is not possible. Remotely, you can use the show disk-group-statistics command to determine if input and output has stopped. Perform these steps: 1. Using the CLI, run the show disk-group-statistics command. The Reads and Writes fields show the number of these operations that have occurred since the statistic was last reset, or since the controller was restarted. Record the numbers displayed. 2. Run the show disk-group-statistics command a second time. This provides you a specific window of time (the interval between requesting the statistics) to determine if data is being written to or read from the disk group. Record the numbers displayed. 3. To determine if any reads or writes occur during interval, subtract the set of numbers you recorded in step 1 from the numbers you recorded in step 2. 24 Procedures
