HP-UX Operating System
Stopping HP-UX
Resetting the V2500/V2600 server hardware
The /spp/bin/do_reset command resets the V-Class hardware. The
do_reset command is run from the Service Support Processor, causes
OBP to reboot, and halts all activity on the V-Class server cabinets
involved. For details see the do_reset man page on the Service Support
Processor.
NOTE Before running do_reset from the Service Support Processor you
should shut down HP-UX running on the V-Class server, if possible, to
avoid losing data.
Four levels of system reset are provided by do_reset, from level 1 (the
default) to level 4 (Transfer of Control).
On multiple-cabinet V-Class server configurations, you can reset all
cabinets or just selected cabinets with do_reset. Larger systems such
as those with additional cabinets take more time to reset.
The do_reset command’s syntax is as follows:
do_reset [node_id | all] [level] [boot_option]
If do_reset is specified with no arguments then the default level 1 reset
of all cabinets is performed, rebooting the server to OBP.
Either a cabinet ID (node_id) or the keyword all can be specified to
indicate which cabinets are to be reset. If a cabinet ID is specified, the
reset level also must be specified.
Reset levels (level) of 1 through 4 are supported and are specified as
numbers. Level 1, the default, provides a hard reset and reboots to OBP.
A level 4 reset provides a Transfer of Control (TOC), equivalent to
pressing the TOC button on a V-Class cabinets.
NOTE Only one request for a level 4 reset (TOC) should be issued at a time.
This ensures that the server properly completes the reset process.
Various boot_options are supported for level 1 resets. Normally only
trained HP service personnel use these.
