RAID Enclosure Thermal Shutdown

Enclosure management provides a feature which automatically shuts down the enclosure when the
temperature within the RAID enclosure reaches dangerous extremes. Thermal shutdown protects the
data on the physical disks from corruption in the event of a cooling system failure.
The temperature at which shutdown occurs is determined by the enclosure temperature probe's Nominal
Failure Threshold and the Maximum Failure Threshold. These thresholds are default settings that
cannot be changed. If the temperature sensors on the backplane or RAID controller module detect a
temperature exceeding the Nominal Failure Threshold, a critical event is set; if the Maximum Failure
Threshold is hit, shutdown of the enclosure power supplies will occur within 5 seconds.

Updating Enclosure Firmware

You can use MD Storage Manager to upgrade the firmware for the RAID controller module, the
controller NVSRAM, and the physical disks. In a redundant configuration, the RAID controller module
firmware can be upgraded with no interruption to data access.

RAID Controller Module Firmware

The RAID controller module firmware and NVSRAM files are needed to properly use MD Storage
Manager and all of its features.
Before you download the RAID controller module firmware or NVSRAM files, ensure that the multi-path
driver (for example, MPP for Linux or MPIO for Windows) is running on the host. In a redundant
configuration, the multi-path driver maintains data access through one RAID controller module while
the other RAID controller module's firmware is upgraded. Also check the MD Storage Manager to see if
it lists both RAID controller modules as optimal. Downloading firmware when either or both controllers
are non-optimal may result in unsynchronized firmware and cause you to have to run the download again
after restoring the RAID controller module(s) to optimal condition.
If a RAID controller is replaced and its firmware does not match the version on the non-replaced RAID
controller, the non-replaced controller will automatically flash the replacement controller with its
firmware version to ensure that both controllers have the same firmware version.
NVSRAM Update
NVSRAM packages specify the internal settings for the storage array RAID controller modules. These
internal settings cannot be modified except by an NVSRAM update. You can download RAID controller
module firmware and NVSRAM packages separately or together using MD Storage Manager.
