SnapDrive for UNIX supports FC and iSCSI multipath access to the storage systems using the standard multipathing software solution. By using multipathing, you can configure multiple network paths between the host and storage system.
SnapDrive for UNIX supports AIX NativeMPIO over iSCSI, when the host connected to the two storage systems are in a HA pair using an interconnect.
If one path fails, the FC or iSCSI traffic continues on the remaining paths. Multipathing is required if the host has multiple paths to a LUN, and it works by making the underlying paths transparent to the user. If the multipathing solution specified in the configuration file for SnapDrive for UNIX operations is configured and supported, SnapDrive for UNIX uses the specified multipathing solution.
