- ACTIVE-ACTIVE / PREFERRED_PATH (Default)
When multiple paths are used for connection between the host and the ETERNUS
DX Disk storage system, there are recommended paths and non-recommended
paths. While the volume can be accessed by using either types of paths, if a non-
recommended path is used, the responses to the host may require a longer period
of time.
- ACTIVE / ACTIVE
When multiple paths are used for connection between the host and the ETERNUS
DX Disk storage system, any paths can be used equally.
When ETERNUS Multipath Driver is used, the "Asymmetric/Symmetric Logical Unit
Access" setting is disabled. This setting value is available for multipath drivers, such as
Oracle/Sun standard multipath drivers or the Solaris 10 Leadville environment which
can control multipath operations between the device and the server with commands.
