Recovery Operations for Processors

The architecture of Integrity NonStop NS-series servers offers recovery options not
available in NonStop S-series. Because a logical processor has a physical processor
element (PE) in each of up to three NonStop Blade Elements, in some cases, you no
longer have to choose between taking the time to dump entire processors and skipping
the dump to reload the system as quickly as possible. In those cases, you can reload a
halted processor immediately, while excluding the PE for one Blade Element, then
dump that excluded PE before reintegrating the Blade Element into the running
processor.
Note. The parts of this section that do not apply to Integrity NonStop NS1000 systems include
all references to processor elements (PEs) the RELOAD command OMITBLADE option. For
more information on Integrity NonStop NS1000 systems, see

NonStop NS1000 Hardware Installation Manual.
Processor recovery operations for your NS-series system might include:

Backing Up a Processor Dump to Tape
Replacing Processor Memory
Replacing the Processor Board and Processor Entity
Submitting Information to Your Service Provider
Recovery Operations for a Processor Halt
HP Tandem Failure Data System (TFDS) should be used to proactively monitor
processors and manage processor halts. Configured and running before a halt occurs,
TFDS can help determine and perform the type of recovery operation needed (see
Monitoring Processors Automatically Using TFDS
configuring and using TFDS, see the Tandem Failure Data System (TFDS) Manual.
If all processors have halted (the system is down), TFDS cannot perform an automatic
dump or reload. You must load the system, as described in
From a Specific Processor
load operation, to dump after the system is running. You can also dump the remaining
processors as needed—dump the entire processor before reloading, or reload and
omit Blade Element to dump later. For more information, see
Disk on page 9-15.
