Multipathing Software
Multipathing software enables you to define and control redundant physical paths
to I/O devices, such as storage devices and network interfaces. If the active path to
a device becomes unavailable, the software can automatically switch to an alternate
path to maintain availability. This capability is known as
automatic failover . To take
advantage of multipathing capabilities, you must configure the server with
redundant hardware, such as redundant network interfaces or two host bus adapters
connected to the same dual-ported storage array.
For your server, three different types of multipathing software are available:
sc> showfaults
ID FRU Fault
0 FT0.F2 SYS_FAN at FT0.F2 has FAILED.
sc> showfaults -v
ID Time FRU Fault
0 MAY 20 10:47:32 FT0.F2 SYS_FAN at FT0.F2 has FAILED.
