2. Set the parameter called the “Controller Unique Identifier” to the correct value:
a. From the firmware Main Menu, select “view and edit Configuration
parameters,” select “Controller Parameters,” and press Return.
b. From the Controller Parameters menu, choose “Controller Unique Identifier
<hex>” and press Return. Type the value 0 (to automatically read the chassis
serial number from the midplane) or type the hex value for the original serial
number of the chassis (used when the midplane has been replaced).
The Controller Unique Identifier is used to create Ethernet addresses and
worldwide names. The value 0 is immediately replaced with the hex value of the
chassis serial number. A nonzero value should be specified only if the chassis has
been replaced, but the original chassis serial number must be retained; this feature
is especially important in a Sun Cluster environment, to maintain the same disk
device names in a cluster.
3. To implement the revised configuration settings from step 1 and step 2, choose
“system Functions” from the Main Menu, choose “Reset controller” and press
Return.
6.2 Replacing SCSI I/O Modules
Be sure to follow “Static Electricity Precautions” on page 1-5.
Caution – The SCSI I/O modules are hot-serviceable only if you disable the
Periodic Drive Check Time parameter through the firmware application; this is not
the preferred procedure. Hot-serviceable means that the module can be replaced while
the array and hosts are powered on, but the connected hosts must be inactive.
6.2.1 Installing Gaskets If Needed
Prior to installing the I/O module, check to see if there is a 1/4-inch thin gasket on
the top inside edge of the I/O module slot on the chassis.
If the gasket is on that edge, do not use the gasket provided with the I/O module
FRU.
If there is no gasket on the top inside edge of the I/O module slot, install the
enclosed gasket as follows:
1. Remove the plastic white backing on the back of the gasket.
