红帽全球峰会4.6. Configuration file overrides section
The overrides section applies configuration changes to all devices, with optional protocol-specific subsections that take precedence over device and default settings.
The overrides section recognizes the optional protocol subsection, and can contain multiple protocol subsections. The system matches path devices against the protocol subsection, using the mandatory type attribute. Attributes in a matching protocol subsection have priority over attributes in the rest of the overrides section. If there are multiple matching protocol subsections, later entries have higher priority. For more information, see the multipath.conf(5) man page on your system.
The protocol subsection recognizes the following mandatory attribute:
| Attribute | Description |
|---|---|
|
| Specifies the protocol string of the path device. Possible values include: |
|
| |
| This attribute is not a regular expression. The path device protocol string must match exactly. |
The attributes in the following list are optional for the protocol subsection. If you do not set them, default values from the overrides, devices or defaults sections apply.
