showq shows less active nodes as normal
Hi,
I am new in system administration. I observe that some nodes in our cluster
are not considered as active by showq:
22 active jobs 217 of 257 processors in use by local jobs (84.44%)
15 of 17 nodes active (88.24%)
but then I try to log into each of the nodes by ssh and they are working,
well at least I can log in.
Is there any command to know what is happening with the nodes
besides showq? I have tried
pbsnodes and it shows some nodes as exclusive and the others as free but none of
them as down.
We are running:
Red Hat Enterprise Linux Workstation release 6.1 of 64 bit.
thanks.

cmscancl
cmscancl(1m) cmscancl(1m)
NAME
cmscancl - gather system configuration information from nodes with Serviceguard installed.
SYNOPSIS
cmscancl [-n node_name]... [-s|-o output_file]
DESCRIPTION
cmscancl 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 configuration 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 information 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 cluster.
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 VALUE
cmscancl 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 cluster 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 cluster and display the output on the screen:
cmscancl -s
To gather the configuration information from all the nodes in the cluster and save the output to the file /tmp/scancl.out:
