avbdiagnose(1) BSD General Commands Manual avbdiagnose(1)NAME
avbdiagnose -- diagnostic tool for AVB.
SYNOPSIS
avbdiagnose
DESCRIPTION
The avbdiagnose tool is used to capture a snapshot of the current AVB system state and help diagnose common issues with AVB.
avbdiagnose looks for the system to determine that it actually has AVB capable interfaces and that at least one of these has been enabled.
avbdiagnose will produce a number of warnings which may not be errors depending on the setup of the system. Things such as missing local or
remote attributes for MSRP will be flagged as a warning but is not an error if the Mac is not sourcing or sinking streams as appropriate for
the warning.
avbdiagnose will flag potential errors and warnings and suggest filing a radar report at http://bugreporter.apple.com. Please attach the
generated file at /tmp/avbdiagnose-<date>.bz2 to the bug report. An error or warning report may be the result of a network device. Please use
your best judgement before filing the bug report.
The following options are available:
--no-enumeration
Disable the reading of the AVDECC AEM from the device and archiving it in the result.
--no-coreaudio
Disable dumping of the state of the AVB audio driver device tree.
--acmp-state
Enabled reading of and dumping the ACMP state of the entities.
--stream-info
Enable sending of the AVDECC AECP AEM GET_STREAM_INFO command to each of the possible stream sources and sinks and including in the info
dump.
--stream-counters
Enable sending of the AVDECC AECP AEM GET_COUNTER command to each of the possible stream sources and sinks and including in the info
dump.
--no-info-tree
Disable dumping of the state of the AVB info tree.
--no-timesync
Disable dumping of the state of the Time Sync info tree.
FILES
/tmp/avbdiagnose-<date>.bz2 output The information gathered by avbdiagnose including the command line output, an ioreg dump
and the current system.log and kernel.log files.

LVMDUMP(8) System Manager's Manual LVMDUMP(8)NAME
lvmdump - create lvm2 information dumps for diagnostic purposes
SYNOPSIS
lvmdump [options] [-d directory]
DESCRIPTION
lvmdump is a tool to dump various information concerning LVM2. By default, it creates a tarball suitable for submission along with a prob-
lem report.
The content of the tarball is as follows:
- dmsetup info
- table of currently running processes
- recent entries from /var/log/messages (containing system messages)
- complete lvm configuration and cache (content of /etc/lvm)
- list of device nodes present under /dev
- list of files present /sys/block
- list of files present /sys/devices/virtual/block
- if enabled with -m, metadata dump will be also included
- if enabled with -a, debug output of vgscan, pvscan and list of all available volume groups, physical volumes and logical volumes will be
included
- if enabled with -c, cluster status info
OPTIONS -h -- print help message
-a -- advanced collection
WARNING: if lvm is already hung, then this script may hang as well if -a is used
-m -- gather LVM metadata from the PVs
This option generates a 1:1 dump of the metadata area from all PVs visible to the system, which can cause the dump to increase in
size considerably. However, the metadata dump may represent a valuable diagnostic resource.
-d directory -- dump into a directory instead of tarball
By default, lvmdump will produce a single compressed tarball containing all the information. Using this option, it can be instructed
to only produce the raw dump tree, rooted in directory.
-c -- if clvmd is running, gather cluster data as well
ENVIRONMENT VARIABLES
