Configuring Fast Boot Settings (Self Tests)
for a nPartition
The fast boot settings for an nPartition determine which self tests the
partition performs during the power on or partition boot process.
You can configure nPartition fast boot settings by enabling and disabling
various self tests using these methods:
• BCH on page 191
This procedure (Configuration menu, FASTBOOT command)
configures an nPartition’s fast boot settings using its BCH interface.
• HP-UX on page 191
This procedure (using the setboot command) configures an nPartition’s
self test configuration from HP-UX running on the partition.
NOTE HP recommends that all self tests be performed for nPartitions.
When an nPartition reboots due to a system panic, HPMC, or TOC, all
self tests are performed when the partition reboots.
On HP nPartition servers you can configure the following self tests:
• PDH tests—Processor-dependent hardware tests that test a
checksum of read-only memory.
Can be configured from BCH and HP-UX setboot as “PDH”.
• Early CPU tests—Firmware, cache, and CPU-specific tests that are
performed out of firmware.
Can be configured from BCH (as “EARLY”) and HP-UX setboot (as
“early_cpu”).
• Late CPU tests—Firmware, cache, and CPU-specific tests that are
performed out of memory and thus are faster than early CPU tests.
Can be configured from BCH (as “LATE”) and HP-UX setboot (as
“late_cpu”).
