Cluster I/O Protocols (CIP) Configuration and Management Manual (H06.16+, J06.05+)

Falling Back to Previous RVUs that Support the Multiple Providers per CLIM
Feature
You can fall back to a previous RVU that is supported by Multiple Providers per CLIM, but keep
an IP and OPEN MODE (Telco or IB) CLIM at the new level if it is either configured with MULTIPROV
OFF, or you install the minimum SPRs to support the Multiple Providers per CLIM feature along with
that RVU.
Although Multiple Providers per CLIM support is effective with the J06.14/H06.25 or subsequent
RVUs, you can also use Multiple Providers per CLIM on NonStop operating systems with IP and
OPEN MODE (Telco or IB) CLIMs beginning with the J06.08/H06.19 RVUs with a defined set of
SPRs. Refer to the Cluster I/O Module (CLIM) Software Compatibility Reference for specific
information on which SPRs are supported for each RVU.
You only need to take fallback action on CLIMs configured with MULTIPROV ON. To determine if
any CLIMs are configured in this manner, issue the SCF INFO CLIM $ZZCIP.* command.
Delete the multiple provider associations and turn the MULTIPROV attribute off, as described under
“Disabling the MULTIPROV Attribute” (page 130).
Falling Back to a Previous CLIM Version
It should never be necessary to fall back to a previous CLIM version, but if you want to do so, have
your service provider see the Reimaging or Downgrading a CLIM service procedure. If you have
to revert the software on the CLIMs during an RVU fallback, see the H06.nn Software Installation
and Upgrade Guide or the J06.nn Software Installation and Upgrade Guide for the RVU you are
currently running. The procedures in those guides account for the timing of CLIM fallback in the
context of a system RVU fallback.
