H06.17 Software Installation and Upgrade Guide

B. When Upgrading From the H06.03 or H06.04 RVU
If you are upgrading from the H06.03 or H06.04 RVU, then before halting the processors, update
the shadow firmware on each NonStop Blade Element, as described in step 6a under “NonStop
Blade Complex Firmware Update for Migrations From H06.03 or H06.04 to This RVU” (page 30).
C. When Upgrading From the H06.16 RVU
CLIMs configured with the CLIM software released with H06.16 are not compatible with H06.17
and later RVUs. Performing the CLIM upgrade when the processors are halted, as shown in this
procedure, ensures the CLIM and host system will be compatible when you restart the system. For
migrations from H06.16, do not perform an online upgrade to the CLIMs before the RVU upgrade.
Preliminary online CLIM upgrades are only supported for H06.17 and later H-series RVUs.
2. Halt the Processors
1. Log on to the OSM Low-Level Link.
2. On the toolbar, click Processor Status to display the Processor Status dialog box.
3. Under Processor Status, select all processors.
4. From the Processor Actions list, select Halt.
5. Click Perform action.
6. Click OK when asked “Are you sure you want to do Halts?”
7. When the Action Status box confirms that all processors have halted, close the Processor Status
dialog box.
3. Power Cycle the Processors if Necessary
If you are upgrading from the H06.03 or H06.04 RVU, while the processors are halted, power
cycle the processors as described in step 6b under “NonStop Blade Complex Firmware Update
for Migrations From H06.03 or H06.04 to This RVU” (page 30).
4. (Required for Upgrade to H06.25) Reset the System Firmware
When upgrading to H06.25 from an earlier RVU, you must perform a hard reset on all processors.
To accomplish a hard reset on all processors, perform all the steps described in “2. Halt the
Processors” (page 110) using OSM Low-Level Link.
NOTE: You must perform this operation on any system moving to the H06.25 RVU.
NOTE: You do not need to perform this operation again if you already performed the hard resets
specified in “2. Halt the Processors” (page 110).
NOTE: You do not need to perform this operation again during subsequent system loads, provided
the previously executing RVU was at least H06.25.
5. (Optional) Upgrade the CLIM Software
If you have not upgraded the CLIMs online before performing this RVU upgrade, upgrade the CLIM
software on each CLIM now. See Upgrading CLIM Software Using OSM Low-Level Link in the
Cluster I/O Protocols (CIP) Configuration and Management Manual.
6. Loading the System
If the automatic system load is not successful using one load path, the system load task attempts
to use another path and keeps trying until all possible paths have been used or the system load is
successful. Eight paths are available for loading.
The command interpreter input (CIIN) file is automatically invoked after the first processor is loaded.
The CIIN file contains the TACL RELOAD * command, which loads the remaining processors.
