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

system down time, such as during RVU upgrades. As a result of this new option, this chapter now
contains completely separate procedures for:
• “Upgrading CLIM Software and Firmware While Maintaining Network or Storage Traffic”
(page 136)
• “Upgrading CLIM Software or Firmware While the System is Down ” (page 165)
CAUTION: Before attempting the procedures in this section:
• Ensure that the NonStop console has at least 2 GB memory (4 GB is recommended), before
upgrading your CLIMs.
• Be sure that the CLIM software is compatible with the host RVU you are currently running. For
more information, see “CLIM and Host Incompatibility” (page 125).
• Fix all alarms and bad attribute values in the OSM Service Connection before upgrading
CLIMs.
• “Upgrading CLIM Software and Firmware While Maintaining Network or Storage Traffic”
(page 136) requires careful planning (as described in this section) and execution to ensure the
storage and networking resources that support your environment are protected.
• “Upgrading CLIM Software or Firmware While the System is Down ” (page 165) involves
having the requisite software and advance preparation (as described in this section) before
bring the system down.
• Ensure the version of OSM Low Level Link has been updated to the requisite version as specified
in the T0853 softdoc.
Upgrading CLIM Software and Firmware While Maintaining Network or
Storage Traffic
This section describes the procedures for upgrading CLIM software and firmware when you are
not planning to bring the system down. It consists of two parts:
• “Upgrading CLIM Software with the System Running” (page 136)
• “Upgrading CLIM Firmware with the System Running” (page 150)
If you plan to bring down the system, as needed during an RVU upgrade, see “Upgrading CLIM
Software or Firmware While the System is Down ” (page 165) for a faster, more efficient process.
TIP: If you are updating a system with SPRs, without a SUT update, and if you need to perform
a CLIM software update, you can do updates in this order and perform only one reboot:
1. Apply the SPRs.
2. Update firmware using OSM Service Connection Multi-Resource Actions dialog box (see
“Upgrading CLIM Firmware with the System Running” (page 150)) but do not reboot the CLIM.
3. Update CLIM software (see “Updating CLIM Software Using the OSM Low-Level Link” (page 147))
including the reboot of the CLIM.
Upgrading CLIM Software with the System Running
You can perform CLIM software updates either one CLIM at a time or multiple CLIMs in parallel.
If you are comfortable performing more than one CLIM upgrade at a time, additional considerations
for group updates are provided in:
• “Upgrading Multiple CLIMs in Parallel” (page 160)
• “Upgrading Multiple CLIMs of Different Types” (page 165)
