Blade Resource Attributes With HP Superdome 2 nPartitions, blade attributes are specified with the parcreate and parmodify commands. The blade resource attributes are: • blade_path Specifies the blade resource path. It can be specified in short, medium, or long format. For example, the blade located in enclosure 1, slot 3 is identified in the short format as 1/3, in the medium format as blade-1/3, or in the long format as enclosure1/blade3. • blade_type Specifies the type of the blade. At initial release, the only valid blade_type value for blades is base. • use_on_next_boot Specifies whether the blade will participate in the next reboot. The valid values for use_on_next_boot are: y Participate in reboot. This is the default value. n Does not participate in reboot. • failure_usage This field is used by system firmware when an nPartition is booted. If a CPU selftest failure or a DIMM de-allocation failure happens during the blade activation, then this flag is used by the system firmware to determine whether or not, and how, the blade should be integrated into the nPartition at boot time. The valid failure_usage values for blades are: ri deconfig Reactivate with memory interleave. Specifies to integrate the blade as it would normally be integrated. This is the default value. Reactivate the nPartition with the blade excluded from activation. • slm_value Specifies the amount of the memory that will be configured as Socket Local Memory (SLM) for the blade. An slm_value specified using the -a or -c option takes precedence over the slm_value specified using the -L option. The slm_value specified by the -L option is applied to all blades for which an slm_value has not been specified with the -a or -c options. If slm_value is not specified, the operating system specific default is applied. The size of SLM allocated is a best attempt to meet the user requested value. In addition, some amount of ILM may be allocated even when 100% SLM is requested. The slm_value can be expressed in two forms: - As a percentage The percent number can be any number in the range 0 - 100 with a suffix of "%". This number will be rounded up to 12.5%, 25%, 37.5%, 50%, 62.5%, 75%, 87% or 100%. If the blade contains less than 4 GB memory, then the percentage will be rounded to 25%, 50%, 75% or 100%. The specified percentage is applied each time the nPartition boots, thus resulting in a different value if the working memory in the blade is different. For example, a blade in an nPartition has 8 GB memory and the user specifies 50% SLM. When the nPartition boots, 4 GB of that blade's memory will be used as SLM. Later the user shuts down the nPartition, adds another 8 GB memory to that blade. When the nPartition is booted again, the blade now has 16 GB of memory, so 8 GB (50%) is allocated as SLM. - As an absolute number (default) This can also be optionally suffixed by "GB". The slm_value is interpreted as an absolute number of gigabytes of memory. Numbers other than integers and halves are rounded up to the nearest 0.5 GB. For example, 2.5 GB will not be rounded up. However, 2.3 GB will be rounded up to 2.5 GB. For example, a blade in an nPartition has 8 GB memory and the user specifies 4 GB SLM. When the nPartition boots 4 GB of that blade's memory will be used as SLM. Later the user shuts down the 24 Getting Started with nPartitions
