Additional multibos options

You can specify additional logical volumes, file systems, paging space, and so on to be copied to a standby BOS.

Preview option

The preview option, using the -p flag, applies to the setup, remove, mount, unmount, and customization operations. If you specify the preview option, then the operation provides information about the action that will be taken, but does not perform actual changes.

Exclude list file

You can use an optional exclude list with the setup operation. The rules for exclusion follow the pattern-matching rules of the egrep command.

For example, to exclude the contents of the /tmp directory, and avoid excluding any other directories that have /tmp in the path name, edit the exclude file to read as follows: ^./tmp/

Note: All files are backed-up relative to the current working directory ("."). To exclude any file or directory for which it is important to have the search match the string at the beginning of the line, use the caret character (^) as the first character in the search string, followed by the dot character (.), followed by the filename or directory to be excluded. If the file name or directory being excluded is a substring of another file name or directory, then use the caret character followed by the dot character (^.) to indicate that the search starts at the beginning of the line. Use the dollar sign ($) to indicate that the search stops at the end of the line.

Specifying additional BOS objects

By default, only a subset of the BOS file systems are copied to the standby BOS. These file systems currently are /, /usr, /var, /opt, and /home. The boot logical volume is also copied to the standby BOS. You can specify additional logical volumes, file systems, paging space, and so on to be copied to the standby BOS with the -L AddFile flag. The AddFile file needs to contain the logical volume names associated with the active BOS object. For example, if you intended to copy the /mylocal file system, then you would include the name of the logical volume that is mounted over /mylocal (for example, Lv01). See the lsfs command for details about how to match file system mount points to logical volumes. Separate log devices (those not contained within the file systems) are not supported for copy and will not be copied even if listed in the AddFile file.

Note: Only LVM-based objects (that is, objects associated with logical volumes) are supported for multibos copying.

Automatic file system expansion

The multibos -X flag auto-expansion feature allows for automatic file system expansion, if space is necessary to perform multibos-related tasks. Run all multibos operations with this flag.
