Command
Description
xtfile2mem/xtmem2file
Reads CPU or Aries memory and saves it in a file.
Performs binary file-to-MMR/node memory and vice
versa.
xtgenid
Generates HSS physical IDs.
xtgenevent
Injects arbitrary HSS events into the event stream.
xthwerrlog
Displays hardware errors retrieved from
xthwerrlogd
in user-friendly format.
xthwerrlogd
Monitors HW error log messages sent by the ANCC and
by nodes.
xtlogfilter
Filters information from event router log files.
xtmemio
Performs reads or writes to Aries MMRs or node
memory.
xtnetwatch
Watches the Cray system interconnection network for
link control block (LCB) and router errors.
xtnid2str
Converts node identification numbers to physical
names. See the
xtnid2str(8)
man page for more
information.
xtnlrd
Responds to fatal Aries and HSN errors by rerouting the
system.
xtnmi
Sends a non-maskable interrupt to target nodes. See
the
xtnmi(8)
man page for more information.
xtpcimon
Monitors health of PCIe channels for Urika-GX systems.
rackfw
Flashes all devices in the Urika-GX system via out-of-
band (OOB). See the

man page for more
information.
xtshow
Shows components with selected characteristics. See
the
xtshow(8)
man page for more information.
xtsignal
Sends a signal number or software interrupt to a remote
process.
xtwarmswap
Allows Cray dANC cards or high-speed network cables
to be warm swapped. See the
xtwarmswap(8)
man
page for more information.
xthwinv
Retrieves hardware component information for selected
modules.
xtls
Generates a summary of HSN link errors.
xtpe

There are a number of HSS diagnostics commands supported on Urika-GX. These commands need to be run
from a compute node.
WARNING: All HSS diagnostics commands are intended for use by Cray Service Personnel only.
Improper use of these restricted commands can cause serious damage to the system.
