the host ID/LUN mapping after firmware default restoration in order to
access data on the previously configured arrays.
2. Some of the latest firmware updates may be incompatible with the firmware
currently running on your subsystem. These updates may require restoring
firmware defaults before firmware upgrade can actually take place. Before
using the button, it is highly advised to practice the following:
ƒ
Stop host I/Os,
ƒ
Backup your data,
ƒ
Make a list of host ID/LUN mapping information for future
references.
You may also jot down the configured parameters such as the performance
preferences, specific stripe sizes, etc.
3. The third condition that requires restoring defaults is when an administrator
forgets the password configured to control the access to a RAID subsystem.
Before pushing this button, also practice the steps listed above. You can
access array information even without a password.
How to use the button?
After the subsystem is powered down, you can use a straighten paper-clip to
press the button. Press and hold down the button, power on the subsystem,
and wait for the LED to light up to indicate system defaults have already
been restored.
3.2.4 Ethernet Port LEDs
4. GbE host ports, which provide different connection speeds, are located on
the controller faceplate. Shielded or non-shielded, Cat5e straight-through
Ethernet cables can be used to connect the RJ-45 ports to the network. Two
(2) LEDs located on each Ethernet port indicate the Ethernet connection
speed and link status. See the diagram below for the locations of the two (2)
LED indicators. Refer to
Table 3-5 for the LED definitions.
