Firmware updates
Attention: Save the storage subsystem profile before performing any controller or
ESM firmware upgrades. Save the DS3950 storage subsystem profile and all
configuration (*.cfg) files to a server disk that will remain accessible in the event of
a DS3950 storage configuration failure. Do not save these files only to a LUN in
the DS3950 storage subsystem.
For optimal operation of the DS3950 and its attached storage expansion enclosures,
the storage expansion enclosure ESM firmware, the DS3950 controller firmware, the
hard drive firmware, and the NVSRAM (for controllers only) must be up to date.
Go to the following Web site to get the latest updates.

Always check the readme files that are included with the firmware packages for
the most up-to-date information about firmware prerequisites, firmware update
instructions, and host I/O restrictions, if any. Apply the necessary updates before
configuring the storage subsystem arrays and logical drives. Subscribe to My
Support for automatic notifications of firmware or Storage Manager software
updates or any important information about your storage subsystems (see
