3.4.1 Mounting the Diagnostics Tests
Before running the Sun Fire V20z diagnostics tests, you need to mount the Network
Share Volume (NSV) software from the NFS server on which it is located. If you
haven’t installed the NSV on an NFS server yet, refer to the instructions on installing
the NSV software in the Sun Fire V20z Server Installation Guide,
817-5246-xx .
1. Log in to the Sun Fire V20z server SP via SSH by typing the following command
at the NFS server’s command prompt:
# ssh -l manager_or_higher_login SSH_hostname
2. Mount the NSV onto the Sun Fire V20z server SP by typing the following
command:
# sp add mount -r NFS_server_hostname:/directory_with_NSV_files -l /mnt
3. Update the diagnostics software by typing the following command
# sp update diags -P /mnt/diags/NSV_version#
Where version# is the version for the NSV software that was mounted in Step 2. For
example: NSV_V2.0.0.42
4. Continue with “Enabling the Diagnostics Tests” on page 3-6.
3.4.2 Enabling the Diagnostics Tests
Whenever a major component in the system does not function properly, you may
have a component failure. As long as the microprocessor and the input and output
components of the system (the monitor, keyboard, and diskette drive) are working,
you can run diagnostics.
The NSV must be mounted on the service processor in order to run diagnostics
commands. Refer to the Sun Fire V20z Server Installation Guide,
817-5246-xx , for
information on mounting the NSV.
To enable diagnostics, execute one of the following commands:
■ When the Sun Fire V20z platform power is off, run the following command to
boot the server and enable diagnostics:
# diags start
■ When the Sun Fire V20z platform power is on and the operating system is
installed, along with all necessary drivers, use the following command to reboot
the server and enable diagnostics:
# platform set os state reboot-to-diags start
