Locating and Troubleshooting DHCP, TFTP, and DNS Services on the NonStop Dedicated Service LAN

Checking TFTP Status on a CLIM
TFTP services are located on the same CLIMs on which DHCP services are configured. To check
the status of the TFTP service on an individual CLIM, use the following TACL command from any
CLIM on which those services are running:
climcmd clim-name ps -A ~| grep tftp
in.tftpd indicates that the TFTP service is configured and running on the CLIM.
The TFTP service is stopped when the DHCP server is disabled (as described under “Checking
DHCP Status on a CLIM” (page 10)).
Remove HSS files from a CLIM
When using the OSM CLIM Boot Service Configuration Wizard to migrate DHCP, TFTP, and DNS
services between NonStop system consoles and CLIMs, the wizard also copies over the HSS files
required for NonStop BladeSystems and NonStop NS2200 series systems (see “How to Migrate
DHCP, TFTP, and DNS Services” (page 5)). When properly migrated through the wizard, the
OSM Low-Level Link is able to determine whether your LAN is configured to provide DHCP, TFTP,
and the HSS boot files required for NonStop BladeSystems and NonStop NS2200 series systems
on primary and backup NonStop system consoles or on a pair of designated CLIMs. Accordingly,
the Low-Level Link knows where to update the HSS files when it is used to perform an Update HSS
action.
If you want to remove HSS files from a CLIM no longer being used for that purpose, use the following
command on that CLIM:
climcmd clim-name rm /opt/hp/Images/hss-filename
