PFU is enabled, you may need to wait 30 minutes to ensure that the two controllers-with their respective ownership of the disk groups-have enough time to fully stabilize. IMPORTANT: Use the SMC or the CLI to perform a restart only if necessary. See the "Restarting controllers" topic in the Storage Manager Guide for more information. Using the SMC To restart the controller using the SMC: 1. Sign-in to the SMC. 2. In the System panel in the banner, click and select Restart System. The Controller Restart and Shut Down panel opens. 3. Select the Restart operation. 4. Select the controller type to restart: Management or Storage. 5. Select the controller module to shut down: A, B, or both. 6. Click OK. A confirmation panel appears. 7. Click Yes to continue; otherwise, click No. If you clicked Yes, a message describes shutdown activity. NOTE: If an iSCSI port is connected to a Microsoft Windows host, the following event is recorded in the Windows event log: Initiator failed to connect to the target. Using the CLI If the enclosure's Unit Locator LED is on, run the following command to turn it off: set led enclosure 0 off If the Fault/Service Required LED is amber, the controller module has not gone online, and likely failed its self-test. Put the module online by restarting the controller, or by checking the event log for errors. To restart the Management Controller (A or B), run the following command: restart mc a or restart mc b or restart mc both To restart the Storage Controller (A or B), run the following command: restart sc a or restart sc b or restart sc both TIP: See the Lenovo Storage S3200/S2200 Setup Guide for descriptions of model-specific LEDs. Updating firmware You can view the current versions of firmware in controller modules, expansion modules (in optional drive enclosures), and disks, and you can also install new firmware versions. TIP: To ensure success of an online update, select a period of low I/O activity. This helps the update complete as quickly as possible and avoids disruptions to hosts and applications due to timeouts. Attempting to update a storage system that is processing a large I/O-intensive batch job could cause hosts to lose connectivity with the storage system. A controller enclosure can contain one or two controller modules. In a dual-controller system, both I/O modules (IOMs) should run the same firmware version. You can update the firmware in each IOM by loading a firmware file obtained from support.lenovo.com (select Product Support and navigate to Storage Products.).

Updating firmware
You can view the current versions of firmware in controller modules, expansion modules (in optional drive
enclosures), and disks, and you can also install new firmware versions.
TIP:
To ensure success of an online update, select a period of low I/O activity. This helps the update
complete as quickly as possible and avoids disruptions to hosts and applications due to timeouts.
Attempting to update a storage system that is processing a large I/O-intensive batch job could cause hosts
to lose connectivity with the storage system.
A controller enclosure can contain one or two controller modules. In a dual-controller system, both I/O
modules (IOMs) should run the same firmware version. You can update the firmware in each IOM by
loading a firmware file obtained from
support.lenovo.com
(select
