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

After you have determined that a processor is not operating, check that the processor is halted. If
it needs to be halted, see “Halting One or More Processors” (page 130)).
Collect information about the reason for the halt (as described in “Identifying Processor Problems”
(page 128)) to send to your service provider along with the dump file. In the Low-Level Link Processor
Status dialog box, write down the halt code and status message for the processor.
Your options for reloading a processor on a running system are:
• “Using TACL RELOAD to Perform Reload” (page 131)
• “Using the OSM Service Connection to Perform Reload” (page 132)
Following the reload, if TFDS is not configured to take the dump automatically on NonStop
NS16000 series and NS14000 series systems, you can perform a dump of the omitted PE while
normal operations resume on the reloaded PEs within that logical processor. See the “Dumping a
Processor Using RCVDUMP for NonStop NS16000 Series and NS14000 Series Systems” (page 136).
Using TACL RELOAD to Perform Reload
Run the RELOAD utility to reload the remaining processors after the first processor in a system has
been brought up, or to recover a processor that has failed.
For NonStop NS16000 series and NS14000 series systems, the H-series RELOAD utility allows
you to omit (or exclude) a Blade Element from the reload operation. This allows you get the processor
running for the PEs on the other Blade Elements, take a dump of the PE on the omitted Blade Element,
and then reintegrate it back into the running processor. The OMITSLICE parameter allows you to
specify the Blade Element (A, B, or C) to be excluded from the reload or, used without specifying
a particular Blade Element, OMITSLICE selects a Blade Element to be excluded. The OMITSLICE
parameter applies only to NonStop NS16000 series and NS14000 series systems.
1. From the OSM Low-Level Link, select File>Start Terminal Emulator.
2. From the menu, select For Startup TACL. If you are using OSM Low-Level Link version T0633AAT
or later, an MR-Win6530 session is opened.
3. In the Enter Telnet IP Address box, type the IP address that is currently configured for your
primary service connection. If the processor for the primary service connection IP address is
down, type the IP address that is currently configured for your backup service connection.
4. Click OK. The TACL window is active, and the TACL1> prompt appears.
5. Enter the super ID (255,255) and press Enter.
6. Type the password and press Enter.
A $SYSTEM STARTUP 1> prompt appears (the prompt depends on your defaults).
7. Use the RELOAD command as appropriate for your scenario.
NOTE: If you plan to dump the PE for one Blade Element after reloading, use RELOAD with
the OMITSLICE parameter. If you don’t know which Blade Element to specify, use OMITSLICE
without specifying A, B, or C. RELOAD will choose an appropriate Blade Element, and reply
with the letter of the Blade Element that was omitted. Use this to specify the Blade Element in
the RCVDUMP command.
RELOAD [ / run-option [ , run-option ] ... / ]
cpu-set [; cpu-set ] ...
run-option
is any of the options described in the RUN[D|V] Command, in the HP NonStop TACL
Reference Manual.
cpu-set
is a set of processors (and options) to be reloaded. Specify cpu-set as:
{ cpu-range } [, option, option, ... ] { ( cpu-range, cpu-range, ...) } { * }
