Specifications

The system performs self-test diagnostics and responds with the console
prompt >>>.
2. Type show device at the >>> prompt to list the devices available to the
AlphaServer.
The system responds with a list of controllers and disks that are connected to
the system. In the description field on the right of the screen, you should see a
list of all devices assigned by the ESS. Disk devices begin with the letters “dk”.
If you do not see a list of devices, verify the SCSI connections, connectors, and
terminators on the bus. If you still do not see a list of devices, check the ESS to
ensure that the ESS is operating correctly.
3. When the list of the devices is displayed on your screen, type Boot to restart the
system.
Operating system device recognition
After the system has restarted, perform the following steps to verify that UNIX
recognizes the disks:
1. Open two new terminal windows.
2. Type uerf -R 300|more on the command line in each of the windows.
A list of device names that begin with the letters “rz” is displayed in each
window. For example, device names should look like the following:
rz28, rz29, rzb28, and rzb29
3. Compare the lists to determine which ESS devices you want to add to the
system.
Device special files
If you install a serial storage architecture (SSA) device after the initial operating
system installation, you must make the device special files that create the character
devices needed for file systems. Perform the following steps:
1. Type: #cd/dev
2. Type: # ./MAKEDEV rzxx, where xx is the number portion of the device name.
For each new drive that you installed in the SSA device, type # ./MAKEDEV rzxx,
where xx is the number portion of the device name.
Initializing disk device
After the list of devices has been determined, you must label the disk volume sizes.
Perform the following steps to label the disks:
1. Write the new label by typing: #disklabel –rw rz28 ESS
2. Verify the label by typing: #disklabel rz28
The #disklabel rz28 command shows the new partition layouts on the Compaq
Tru64 and automatically detects the LUNs that are provided by the SSA device.
Configuring AdvFS
Before you create an AdvFS file system, you must design a structure by assigning a
file domain and the file sets. Perform the following steps to create an AdvFS file
system with file sets:
1. Type: #cd/
2. Type: # mkfdmn –rw /dev/rzXc vol1_dom
3. Type: # mkfset vol1_dom vol1
4. Type: # mkdir /vol1 # mount vol1_dom#vol1 /vol1
To display all mounted devices, type: df -k
