Migrate CLIM Services and Disconnect CLIMs
The H06.15 RVU and earlier H-series RVUs do not support CLIMs. If you are using CLIMs and
intend to fall back to H06.15 or an earlier H-series RVU, follow these general guidelines:
1. Use the CLIM Boot Service Configuration Wizard or the NonStop Maintenance LAN DHCP
DNS Configuration Wizard to determine if services such as DHCP, DNS, or BOOTP are
configured on the CLIMs or on the NonStop Console.
2. If the services are configured on any of those CLIMs, you will need to migrate those services
to other CLIMs or to system consoles. See Changing the DHCP, DNS, or BOOTP Server from
CLIMs to System Consoles or Changing the DHCP, DNS, or BOOTP Server from System
Consoles to CLIMs, as appropriate.
3. Disconnect the CLIMs that are installed on the affected system.
If Falling Back to the H06.03 or H06.04 RVU
If you are falling back to the H06.03 or H06.04 RVU, before halting the processors, update the
shadow firmware on each NonStop Blade Element, as described under “Reverting to H06.03 or
H06.04 From This RVU” (page 156).
