Versioned WPAR file system and network considerations
File system considerations: By default, the file system characterizations for a versioned WPAR are derived from the characteristics of the source system from which the backup was made. The logical volume characteristics from the backup are not used by default. The -M flag of mkwpar might be used to set file system characteristics as with a regular WPAR. It is the responsibility of the administrator to determine the amount of space required for the WPAR if -M is used.
Additional options that can be used to control the file system
characteristics of a versioned WPAR follow:
- -g
- Set the default volume group to use for the WPAR. The default is rootvg.
- -L shrink=yes
- Use only the minimum file system space for the WPAR.
- -L ignore_lvs=no
- Use the logical volume characteristics from the backup for the WPAR. Use this option only if you have a good understanding of LVM, because the characteristics from the backup can conflict with logical volumes on the target system.
- -L image_data=none
- Ignore all file system characteristics from the backup. There must be -M mount specifications for the base file systems (/, /usr /opt, /home, /tmp, and /var) in this case or else the default characteristics for a regular WPAR are used.
Network considerations: Network characteristics from a restored system are not preserved. The network characteristics are established from the network and host name specifications that were used when the system created the versioned WPAR.
