The multipath-tools package automatically detects the following storage arrays:
|
|
In general, most other storage arrays should work. When storage arrays are automatically detected, the default settings for multipathing apply. If you want non-default settings, you must manually create and configure the /etc/multipath.conf file. For information, see Section 5.4.5, Creating and Configuring the /etc/multipath.conf File.
Hardware that is not automatically detected requires an appropriate entry for configuration in the DEVICES section of the /etc/multipath.conf file. In this case, you must manually create and configure the configuration file. For information, see Section 5.4.5, Creating and Configuring the /etc/multipath.conf File.
Consider the following caveats:
The following storage arrays have been tested with SUSE Linux Enterprise Server:
Most other vendors’ storage arrays should also work. Consult your vendor’s documentation for guidance. For a list of the default storage arrays recognized by the multipath-tools package, see Storage ArraysThat Are Automatically Detected for Multipathing.
Storage arrays that require special commands on failover from one path to the other or that require special nonstandard error handling might require more extensive support. Therefore, the Device Mapper Multipath service has hooks for hardware handlers. For example, one such handler for the EMC CLARiiON CX family of arrays is already provided.
IMPORTANT:Consult the hardware vendor’s documentation to determine if its hardware handler must be installed for Device Mapper Multipath.
The multipath -t command shows an internal table of storage arrays that require special handling with specific hardware handlers. The displayed list is not an exhaustive list of supported storage arrays. It lists only those arrays that require special handling and that the multipath-tools developers had access to during the tool development.
IMPORTANT:Arrays with true active/active multipath support do not require special handling, so they are not listed for the multipath -t command.
A listing in the multipath -t table does not necessarily mean that SUSE Linux Enterprise Server was tested on that specific hardware. For a list of tested storage arrays, see Tested Storage Arrays for Multipathing Support.
