WLM (workload manager) currently uses the Unix command "uname -i" to ensure that all the partitions it
is managing are on the same Superdome. WLM verifies that all the managed partitions "uname -i" values
match. It turns out the Integrity partitions and PA partitions on the same Superdome do not return the
same value for "uname -i". This prevents WLM from properly managing all the partitions on a single
Superdome in a mixed environment with iCAP. The WLM team has provided patches WLM A.03.00 for
both 11.i v1 (PHSS_33499 - s700_800 11.11 WLM A.03.00 Cumulative Patch) and 11.i v2
(PHSS_33477 - s700_800 11.23 WLM A.03.00 Cumulative Patch) to resolve this issue. Customers who
wish to use WLM in a mixed environment with iCAP will need to install/upgrade to version A.03.00 and
install the appropriate patch. Customers who are using either WLM A.02.x or A.03.x in a non-iCAP
environment can use their current version of WLM with no upgrade/patch. Future versions of WLM
(A.03.00.01 and later) will not require a patch.

gWLM 1.1.1 (global workload manager) was first released with HPUX 11.i v2 HWE0505. It has the same
issue with "uname -i" as WLM. This only affects gWLM iCAP SRDs. VPAR, PSET and FSS SRDs work
correctly in mixed environments. The gWLM team plans to remedy this issue in the first maintenance
release of gWLM. Contact gwlmfeedback@rsn.hp.com for a workaround if you have a gWLM 1.1.1
customer who needs to deploy an iCAP SRD on a mixed complex before the first maintenance release is
available.
Global Workload Manager (gWLM V1.1) is also available for OpenVMS on Integrity Servers.
Superdome high availability offering is as follows:

future HP UX release. Online addition/replacement of individual processors and memory DIMMs will
never be supported.)
Processor: The features below nearly eliminate the down time associated with processor cache
errors (which are the majority of processor errors). If a processor is exhibiting excessive cache
errors, HP UX 11i version 2 will ONLINE activate to take its place. Furthermore, the processor
cache will automatically be repaired on reboot, eliminating the need for a service call.
Dynamic processor resilience with Instant Capacity enhancement.

Memory: The memory subsystem design is such that a single SDRAM chip does not contribute

more than 1 bit to each ECC word. Therefore, the only way to get a multiple-bit memory error
from SDRAMs is if more than one SDRAM failed at the same time (rare event). The system is also
resilient to any cosmic ray or alpha particle strike because these failure modes can only affect
multiple bits in a single SDRAM. If a location in memory is "bad", the physical page is deallocated
dynamically and is replaced with a new page without any OS or application interruption. In
addition, a combination of hardware and software scrubbing is used for memory. The software
scrubber reads/writes all memory locations periodically. However, it does not have access to
"locked down" pages. Therefore, a hardware memory scrubber is provided for full coverage.
Finally data is protected by providing address/control parity protection.
