Chapter 3 Subsystem Monitoring

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:

ƒStop host I/Os,

ƒBackup your data,

ƒMake 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 3-5for the LED definitions.
