4 Upgrading CIP
This chapter provides procedures for online upgrading of CIP on the host and both online and
down system methods for upgrading CLIM software and firmware (see “Upgrading CLIM Software
and Firmware” (page 135)). This chapter also provides information on falling back to previous
TCP/IP subsystems and provides a pointer to information on falling back to previous CLIM versions
if needed.
Each procedure stands alone. If you are performing an RVU upgrade, you are likely to need to
upgrade CIP on the NonStop host and on the CLIM; however, you also can upgrade CLIM software
independently. If you have to update CIP on NonStop and the CLIM using an online procedure,
the CLIM must be done first.
Updating CLIM firmware is independent of CLIM software upgrades. Falling back to a previous
CLIM version, independently from an RVU fallback, should rarely be required.
Performing an Online Upgrade of the CIP Subsystem on the NonStop Host
For Telco applications, HP recommends that you:
1. Move traffic from the node.
2. Stop the DPA and HLR application processes on the node.
3. Shut down the INS node before performing an online CIP upgrade.
4. Start the INS node, DPA, and HLR applications.
5. Move traffic back to the node, starting with one link or linkset, and test traffic before moving
all the traffic back.
For information about INS, see the CMS documents Guide to Operations and Maintenance for
HP OpenCall Intelligent Network Serve and the Installation Guide For HP OpenCall Intelligent
Network Server.
NOTE: You cannot perform an online upgrade of the CIP subsystem to J06.08/H06.19 or later
RVUs from an RVU previous to that. A system load is required for these upgrades.
Replace CIPMON (Only)
TCP/IP socket connections are lost during this procedure. Storage paths are unaffected by this
procedure.
For each processor:
1. Rename the existing CIPMON and library files by using the TACL commands:
> RENAME $SYSTEM.SYSnn.CIPMON, $SYSTEM.SYSnn.CIPMONx
> RENAME $SYSTEM.SYSnn.ZCIPDLL, $SYSTEM.SYSnn.ZCIPDLLx
> RENAME $SYSTEM.SYSnn.ZCIPMDLL, $SYSTEM.SYSnn.ZCIPMDLx
2. Install the new CIPMON as $SYSTEM.SYSnn.CIPMON.
3. Install the new CIP library as $SYSTM.SYSnn.ZCIPDLL.
4. Install the new Measure interface to CIP as $SYSTM.SYSnn.ZCIPMDLL.
5. Stop the measure subsystem.
6. Abort the CIPMON processes one processor at a time by using the SCF command:
CAUTION: IP CLIM connectivity is temporarily lost, which can affect this operation. For
example, if you are connected through $ZTC0 and stop the CIPMON process in the processor
where $ZTC0 is running, you lose connectivity. Options are to reconnect through $ZTC1 after
this operation or connect through $ZTC1 and perform this operation on the processor where
$ZTC0 is running then, once the CIPMON is running in that processor, connect through $ZTC0
and perform the operation on the processor running $ZTC1.
