Conﬁguring Fast Boot Settings (Self Tests)

for a nPartition

The fast boot settings for an nPartition determine which self tests the

nPartition performs during the power on or nPartition boot process.

You can conﬁgure nPartition fast boot settings by enabling and disabling

various self tests using these procedures:

• Conﬁguring Fast Boot for an nPartition [BCH] on page 240

This procedure (Conﬁguration menu, FASTBOOT command)

conﬁgures an nPartition’s fast boot settings using its BCH interface.

• Conﬁguring Fast Boot for an nPartition [HP-UX] on page 240

This procedure (using the setboot command) conﬁgures an

nPartition’s self test conﬁguration from HP-UX running on the

nPartition.

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 nPartition 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”).
