Because the HSG80 controller’s configuration information and worldwide
name is stored in nonvolatile random-access memory (NVRAM) on the
controller, there are different procedures for replacing HSG80 controllers
in an RA8000 or ESA12000:
• If you replace one controller of a dual-redundant pair, the NVRAM
from the remaining controller retains the configuration information
(including worldwide name). When you install the replacement
controller, the existing controller transfers configuration information to
the replacement controller.
• If you have to replace the HSG80 controller in a single controller
configuration, or if you must replace both HSG80 controllers in a
dual-redundant configuration simultaneously, you have two options:
– If the configuration has been saved to disk (with the
INITIALIZE DISKnnnn SAVE_CONFIGURATION or INITIALIZE
storageset-name SAVE_CONFIGURATION option), you can restore
it from disk with the CONFIGURATION RESTORE command.
– If you have not saved the configuration to disk, but the label
containing the worldwide name and checksum is still intact, or you
have recorded the worldwide name and checksum (Section 6.5.3.1)
and other configuration information, you can use the command-line
interface (CLI) commands to configure the new controller and set the
worldwide name. Set the worldwide name as follows:
SET THIS NODEID=nnnn-nnnn-nnnn-nnnn checksum
6.6 Installing Tru64 UNIX and TruCluster Server Software
Using Fibre Channel Storage
After the hardware has been installed and configured, there are preliminary
steps that must be completed before you install Tru64 UNIX and TruCluster
Server on Fibre Channel disks.
You may already know the physical devices on which you want to install
Tru64 UNIX and TruCluster Server. That is, you probably know the location
of the devices within the storage cabinet, and are aware that the HSG80
show unit command displays the unit number of each of these devices. For
example, DISK10200 might be unit number D1.
You need to equate the unit number identified by the HSG80 controller
with device names that the AlphaServer console can use. That is, the
AlphaServer console must know about the devices before it can boot from,
or dump to them, and it must have a valid Fibre Channel connection
