Updating firmware You can update the versions of firmware in controller modules, expansion modules (in drive enclosures), and disks. 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 host and applications due to timeouts. Attempting to update a storage system that is processing a large, I/O-intensive batch job will likely cause hosts to lose connectivity with the storage system. IMPORTANT: • If a disk group is quarantined, resolve the problem that is causing the disk group to be quarantined before updating firmware through the CLI. See information about events 172 and 485 in the Event Descriptions Reference Guide, and de-quarantining disk groups in the CLI Reference Guide. • If any unwritten cache data is present, firmware update will not proceed. Before you can update firmware, unwritten data must be removed from cache. See information about event 44 in the Event Descriptions Reference Guide and information about the clear cache command in the CLI Reference Guide. • If the system's health is Fault, firmware update will not proceed. Before you can update firmware, you must resolve the problem specified by the health reason information on the System Health hover panel (page 88). Updating controller-module firmware A controller enclosure can contain one or two controller modules. In a dual-controller system, both controllers should run the same firmware version. You can update the firmware in each controller module by loading a firmware file obtained from the Lenovo web download site at support.lenovo.com. If you have a dual-controller system and the Partner Firmware Update (PFU) option is enabled (PFU is enabled by default), when you update one controller the system automatically updates the partner controller. If PFU is disabled, after updating firmware on one controller you must log into the partner controller's IP address and perform this firmware update on that controller also. For best results, the storage system should be in a healthy state before starting firmware update. NOTE: For information about supported releases for firmware update, see the product's Release Notes. To update controller-module firmware 1. Obtain the appropriate firmware file and download it to your computer or network. 2. In the SMC, prepare to use FTP: a. Determine the network-port IP addresses of the system's controllers. b. Verify that the system's FTP service is enabled. c. Verify that the user you will log in as has permission to use the FTP interface. 3. If the storage system has a single controller, stop I/O to disk groups before starting the firmware update. 4. Open a Command Prompt (Windows) or a terminal window (UNIX) and navigate to the directory containing the firmware file to load. 5. Enter: ftp controller-network-address For example: ftp 10.1.0.9 6. Log in as an FTP user. 108 Using FTP

Using FTP
Updating firmware
You can update the versions of firmware in controller modules, expansion modules (in drive enclosures), and disks.
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 host and applications due to timeouts. Attempting to update a storage
system that is processing a large, I/O-intensive batch job will likely cause hosts to lose connectivity with the storage
system.
IMPORTANT:
•
If a disk group is quarantined, resolve the problem that is causing the disk group to be quarantined before
updating firmware through the CLI. See information about events 172 and 485 in the Event Descriptions Reference
Guide, and de-quarantining disk groups in the CLI Reference Guide.
•
If any unwritten cache data is present, firmware update will not proceed. Before you can update firmware,
unwritten data must be removed from cache. See information about event 44 in the Event Descriptions Reference
Guide and information about the
clear cache
command in the CLI Reference Guide.
•
If the system’s health is Fault, firmware update will not proceed. Before you can update firmware, you must resolve
the problem specified by the health reason information on the System Health hover panel (
page 88
).
Updating controller-module firmware
A controller enclosure can contain one or two controller modules. In a dual-controller system, both controllers should
run the same firmware version. You can update the firmware in each controller module by loading a firmware file
obtained from the Lenovo web download site at
support.lenovo.com
.
If you have a dual-controller system and the Partner Firmware Update (PFU) option is enabled (PFU is enabled by
default), when you update one controller the system automatically updates the partner controller. If PFU is disabled,
after updating firmware on one controller you must log into the partner controller’s IP address and perform this
firmware update on that controller also.
For best results, the storage system should be in a healthy state before starting firmware update.
NOTE:
For information about supported releases for firmware update, see the product’s Release Notes.
