NonStop Operations Guide for H-Series and J-Series RVUs

See “Using RCVDUMP to Dump a Processor to Disk” (page 135).
• If your service provider determines that a processor halt is not divergence-related, you might
be directed to reload the processor while excluding the PE for one Blade Element, which is
then dumped before being reintegrated. In this case, perform the reload (see “Reloading a
Single Processor on a Running system” (page 130)), then use the RCVDUMP command as
follows:
◦ If more than one Blade Element is in the Stopped state, use the SLICE parameter and
specify the Blade Element (A, B, or C) of the PE to be dumped. (If only one Blade
Element is in the Stopped state, it is not necessary to use the SLICE parameter.)
◦ Specify the PARALLEL parameter.
See “Using RCVDUMP to Dump a Processor to Disk” (page 135).
• If a dump is to be taken following a system load, as described in “Performing a System Load
From a Specific Processor” (page 187), options for taking dumps include:
◦ After the processor (0 or 1) has been loaded with a Blade Element omitted, use RCVDUMP
with the PARALLEL option.
◦ You can dump any of the remaining processors either by dumping the entire processor
before reloading them (use RCVDUMP without specifying the ONLINE or PARALLEL
options), or reload with a Blade Element omitted, then dump that Blade Element using
RCVDUMP with the PARALLEL option.
• If you are directed to dump a single PE that is running, use the RCVDUMP command, as
follows:
◦ Specify the ONLINE parameter.
◦ Do not specify the SLICE parameter (RCVDUMP will choose the first running PE).
See “Using RCVDUMP to Dump a Processor to Disk” (page 135).
For NonStop NS16000 series and NS14000 series systems, a processor dump can be made to
as many as four files:
• The file name of the full dump file may end with F.
• File names may end with an A, B, or C to designate which Blade Element the processor element
was dumped from.
Backing Up a Processor Dump to Tape
NOTE: H-series and J-series NonStop systems do not support backing up a processor dump to
tape.
Replacing Processor Memory
Processor memory is field-replaceable for all NonStop systems. Call your service provider. If memory
units cannot be replaced, the memory board must be replaced.
If the Service State attribute of a Blade Element object is not OK (see “Monitoring Processor
Performance Using ViewSys” (page 128)), the memory board might need to be replaced. Contact
your service provider.
Replacing the Processor Board and Processor Entity
Processor boards and entities are field-replaceable for all NonStop systems. Call your service
provider.
