Serviceguard Commands
Appendix A 313
cmquerycl Query cluster or node configuration information.
cmquerycl searches all specified nodes for cluster
configuration, cluster lock, and Logical Volume
Manager (LVM) information. Cluster configuration
information includes network information such as
LAN interface, IP addresses, bridged networks and
possible heartbeat networks. Cluster lock
information is either the quorum server hostname
and IP address or the lock LUN device file data.
LVM information includes volume group (VG)
interconnection and file system mount point
information. This command should be run as the
first step in preparing for cluster configuration. See
“Configuring the Cluster” on page 179. It can also
be used as a troubleshooting tool to identify the
current configuration of a cluster.
NOTE:
Use cmquerycl -c <cluster_name> -C
<filename> to produce a text file (filename)
showing the current configuration of the cluster,
with additional, commented-out, entries for
network subnets that are not currently part of the
the cluster configuration, but can be configured into
it. See “Changing the Cluster Networking
Configuration while the Cluster Is Running” on
page 256.
cmreadlog Format an Object Manager log file for easy display.
This command reads the log files created by Object
Manager in the Managed Object File (MOF) format
and displays them in a report with one entry per
line. Use the command when troubleshooting or
reviewing Object Manager activity.
