Troubleshooting Your Cluster
Solving Problems
Chapter 8382
You can use the following commands to check the status of your disks:
• bdf - to see if your package's volume group is mounted.
• vgdisplay -v - to see if all volumes are present.
• lvdisplay -v - to see if the mirrors are synchronized.
• strings /etc/lvmtab - to ensure that the configuration is correct.
• ioscan -fnC disk - to see physical disks.
• diskinfo -v /dev/rdsk/cxtydz - to display information about a
disk.
• lssf /dev/dsk/* - to check LV and paths.
• vxdg list - to list VERITAS disk groups.
• vxprint - to show VERITAS disk group details.
Package Control Script Hangs or Failures
When a RUN_SCRIPT_TIMEOUT or HALT_SCRIPT_TIMEOUT value is set, and
the control script hangs, causing the timeout to be exceeded,
Serviceguard kills the script and marks the package “Halted.” Similarly,
when a package control script fails, Serviceguard kills the script and
marks the package “Halted.” In both cases, the following also take place:
• Control of a failover package will not be transferred.
• The run or halt instructions may not run to completion.
• AUTO_RUN (automatic package switching) will be disabled.
• The current node will be disabled from running the package.
Following such a failure, since the control script is terminated, some of
the package's resources may be left activated. Specifically:
• Volume groups may be left active.
• File systems may still be mounted.
• IP addresses may still be installed.
• Services may still be running.
