bosinst.data livedump stanza

Edit online

The optional livedump stanza allows you to customize the attributes of the livedump filesystem that is created during a BOS installation.

During a BOS installation, a livedump filesystem is created. To modify the attributes used to create this filesystem, use a customized bosinst.data file with a livedump stanza. The following attributes can be specified:
LD_DIR
The directory where the livedump filesystem will be mounted. If the LD_DIR attribute is not specified, the default directory is /var/adm/ras/livedump.
LD_SIZEMB
The livedump filesystem size in MB. If the LD_SIZEMB attribute is not specified, the default is 256.
LD_DEVICE
The logical-volume name for the filesystem. If the LD_DEVICE attribute is not specified, the default is livedump.

If the livedump stanza does not exist, or is not modified, the livedump filesystem is created with the default values.

Depending on the type of installation, the filesystem is created as follows:
  • Overwrite installations always create a livedump filesystem.
  • Preservation and migration installations create the file system as follows:
    • If you specify attribute values in the livedump stanza, the filesystem is created with those values unless it already exists.
    • If you do not specify attribute values in the livedump stanza, the filesystem is created with default values, if it does not already exist.
