General Guidelines for Troubleshooting Solaris Volume Manager

You should have the following information on hand when you troubleshoot Solaris Volume Manager problems:

• Output from the metadb command.

• Output from the metastat command.

• Output from the metastat -p command.

• Backup copy of the /etc/vfstab file.

• Backup copy of the /etc/lvm/mddb.cf file.

• Disk partition information, from the prtvtoc command (SPARC® systems) or the fdisk command (x86–based systems)

• Solaris version

• Solaris patches installed

• Solaris Volume Manager patches installed

Any time you update your Solaris Volume Manager configuration, or make other storage or operating system-related changes to your system, generate fresh copies of this configuration information. You could also generate this information automatically with a cron job.
