HP-UX 11i v1 automatically installs Support Tools on all systems to provide required hardware support. These tools, contained in the OnlineDiag bundle, give you a complete solution for verifying, troubleshooting, and monitoring HP system hardware. This includes CPUs, memory, interface cards, mass storage devices, and other devices.

To see if the diagnostic drivers are present and to use sam to install them if they are not:

  1. cd /stand

  2. Run the what command on the kernel file from which the system is booted, usually vmunix:

    /usr/bin/what vmunix | grep diag

    If the diagnostic drivers are there, the output contains diag1, and diag2 on workstations and diag0, diag1, and diag2 on servers. If not, load the drivers as follows:

  3. As root, run sam:

    /usr/sbin/sam

  4. From the sam menus, select Kernel Configuration/Subsystems, then select the DIAGNOSTICS subsystem. Pull down the Actions menu and select Add Subsystem to Kernel.

    The third column of the matrix, Pending, should now show In for the DIAGNOSTICS subsystem.

  5. Select Actions -> Process New Kernel. Confirm that you want to reboot the system when prompted.

Help with using Support Tool Manager and the other diagnostics is in the Support Plus: Diagnostics User’s Guide, available on the Support Plus CD in:
