EonStor S12E-R1132-4/G1133-2 Installation and Hardware Reference Manual
․
After you upgrade the controller DIMM module to 2GB,
use this button to restore firmware defaults. This is to
ensure firmware’s embedded 1GB threshold for internal
settings, such as the supported no. of logical drives, is
upgraded.
․
When you forget the password controlling the access to
a RAID system, you also need to restore defaults. After
restoring, you can access array information even without
a password.
Listed below are the procedures that should be
completed before you use this button:
1. Before you press this button to restore firmware defaults,
please save the current configuration using the “
Save
NVRAM
” function in firmware utility or the SANWatch GUI.
2. You should also make a list of the existing ID/LUN mapping
information. You will need the list for restoring ID/LUN
mapping after restoring defaults. Default restoration will
erase the ID/LUN mapping associations (e.g., which logical
drive is associated with which host ID/LUN), and it is
necessary to restore the host ID/LUN mapping after
firmware default restoration in order to access data on the
previously configured arrays.
How to use the button?
CAUTION!
The Restore NVRAM Default push button should be
considered as a last-resort function. Restoring firmware
defaults will not destroy the existing logical drives; however, if
the existing logical drives cannot be adequately associated
with host ID/LUNs after default restoration, data
inconsistencies might occur.
Single-controller:
After the subsystem is powered down, you can use a
straightened paper clip to press the button. Press and hold the
button down, power on the subsystem, and wait for the
associated LED and the subsystem
Ready
LED to light up.
The “
Restore Def.
” LED and the firmware “
Default Restored
”
event indicate successful restoration of firmware defaults.
