optimal. Downloading firmware when either or both controllers are nonoptimal 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. Physical Disk Firmware NOTE: Dell recommends stopping all I/O to the array when downloading physical disk firmware. You can also download physical disk packages containing the latest firmware files. Ensure that the firmware files you select are compatible with the physical disks. Before downloading firmware, you should back up all your data. In addition, do not make any configuration changes to the storage array, such as creating virtual disks or defining host servers, during the download. Doing so could cause the firmware download to fail and prevent access to the physical disks. Expansion Enclosure Firmware You can download firmware updates for your MD1000 expansion enclosures using the MD Storage Manager. Using Your RAID Enclosure 53

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.
Physical Disk Firmware
NOTE:
Dell recommends stopping all I/O to the array when downloading physical
disk firmware.
You can also download physical disk packages containing the latest firmware
files. Ensure that the firmware files you select are compatible with the
physical disks.
Before downloading firmware, you should back up all your data. In addition,
do not make any configuration changes to the storage array, such as creating
virtual disks or defining host servers, during the download. Doing so could
cause the firmware download to fail and prevent access to the physical disks.
Expansion Enclosure Firmware
You can download firmware updates for your MD1000 expansion enclosures
using the MD Storage Manager.
