H06.11 Software Installation and Upgrade Guide

Managing Firmware in a NonStop Blade Complex
NOTE: In TACL commands and event messages, you might see:
• The term slice, which is equivalent to the term NonStop Blade Element (NSBE).
• The term processor complex, which is equivalent to the term NonStop Blade Complex
(NSBC)
The OSM GUI now displays the newer Blade Complex and Blade Element terminology.
NOTE: For details specific to managing firmware in an NS1000 server, see the Updating Blade
Element Firmware in an NS1000 Server procedure in the Support and Services Library in NTL.
The following terms briefly describe the NonStop Blade Complex, which is composed of two or
three NonStop Blade Elements and their associated logical synchronization units (LSUs):
DescriptionTerm
A single Integrity NonStop NS-series microprocessor with its associated memory.Processor element (PE)
Two or four PEs contained within a single processor (blade) complex enclosure.NonStop Blade element
One or more PEs from each NonStop Blade Element executing a single instruction
stream. A duplex processor (DMR) has two PEs forming a logical processor. A triplex
processor (TMR) has three PEs. For example:
Logical processor
The combination of the LSU logic board and the LSU optics adapter. An LSU serves
one logical processor.
Logical synchronization unit
(LSU)
Two slices or Blade Elements (DMR) or three slices or Blade Elements (TMR). An
Integrity NonStop NS-series server includes up to four processor (blade) complexes.
Processor (Blade) Complex
For more information on the NonStop advanced architecture (NSAA), see the NonStop NS-Series
Planning Guide.
Updating processor boot code is part of the Halted State Services (HSS) firmware, which consists
of HSS Main, Primitive State code (pState), SCSI firmware (ISP1040), bootstrap (Diskboot),
Baseboard Management Controller (BMC) firmware, and PAL/SAL firmware (IPF Firmware.)
HSS provides interfaces compatible with existing NonStop interfaces for RELOAD and
RCVDUMP.
You use an OSM guided procedure, launched by performing the Firmware Update action from
the Blade Complex, to update the firmware for each Blade Element in the complex.
