cmscancl(1m)cmscancl(1m)NAMEcmscancl - gather system configuration information from nodes with Ser‐
viceguard installed.
SYNOPSIScmscancl [-n node_name]... [-s|-o output_file]
DESCRIPTIONcmscancl is a configuration report and diagnostic tool intended only
for use by HP Support Personnel. It gathers system software and hard‐
ware configuration information from a list of nodes, or from all the
nodes in a cluster. The information that this command displays
includes LAN device configuration, network status and interfaces, file
systems, LVM configuration, link-level connectivity (HPUX only),
IPv4/IPv6 connectivity, and the data from the binary cluster configura‐
tion file. This command can be used as a troubleshooting tool or as a
data collection tool.
This command is a Perl script which gathers system configuration infor‐
mation by executing various OS commands or tools. It uses the cmexec
command to gather information from remote nodes.
The -n option can be used to specify a list of nodes to be scanned, the
nodes to be scanned do not need to be a member of a cluster. If the -n
option is not specified, it will scan all the nodes in the local clus‐
ter.
By default, the output of this command will go to the file
/tmp/scancl.out. If the file /tmp/scancl.out already exists, the old
file will be saved in /tmp/scancl.out.old.
The -o option can be used to redirect output to a specified output
file. If the -o option is not specified, output will go to the default
output file /tmp/scancl.out.
The -s option can be used to direct all output to the screen, instead
of to an output file.
Options
cmscancl supports the following options:
-n node_name... Specify the node(s) to be scanned. If this
option is not specified and there is a cluster
configured, all the nodes in the cluster will
be scanned. If this option is not specified
and there is no cluster configured, only the
local node will be scanned.
-o output_file Write configuration information to a specified
output file. If this option is not specified,
the information will be directed to stdout.
-s Display the configuration information to the
screen only. This option cannot be used in
conjunction with the -o option.
The output from this command contains the following information:
LAN device configuration (On HP-UX, output from lanscan; On
Linux, output from ifconfig)
network status and interfaces (output from netstat)
file systems (output from mount)
LVM configuration (contents of /etc/lvmtab file)
LVM physical vg information (contents of /etc/lvmpvg file)
link-level connectivity (HP-UX only)
(output from linkloop)
IPv4/IPv6 connectivity (results from ping (and ping6 on
Linux))
binary configuration file data
(output from cmviewconf)
RETURN VALUEcmscancl returns the following value:
0 Successful completion.
1 Command failed.
EXAMPLES
To gather the configuration information from node1 and node2 and to
save the output in file /tmp/scancl.log:
cmscancl-n node1 -n node2 -o /tmp/myscancl.log
To gather the configuration information from all the nodes in the clus‐
ter and save the output to the file: /tmp/scancl.log:
cmscancl-o /tmp/myscancl.log
To gather the configuration information from all the nodes in the clus‐
ter and display the output on the screen:
cmscancl-s
To gather the configuration information from all the nodes in the clus‐
ter and save the output to the file /tmp/scancl.out:
