Multipathing in Solaris is a technique that allows a host to access multiple paths to a single storage device. This can improve performance and reliability by providing redundancy in case of a path failure.
There are several ways to check multipathing in Solaris. One way is to use the multipath command. This command will display information about the multipathed devices on the system. Another way to check multipathing is to use the devfsadm command. This command will display information about the devices on the system, including the multipathed devices.
