In NEC Storage PathManager, two types of failback methods are available: active fail back and standby
failback.
/1/ Active failback
Failback is executed and the state of the path becomes active. The priority of a path that failed back
becomes enabled. There may be a case where paths are switched at the time of failback, and the state of
the path becomes "In use."
/2/ Standby failback
Failback is executed and the state of the path becomes standby. The priority of a path that failed back
becomes disabled. Select standby failback when you do not wish to have any extra path switching at
the time of failback. If this type of failback is selected, it is necessary to manually enable the path
priority after failback is complete.
Use the -setfbmode option of the spscmd to select the type of failback.
C:\>spscmd -setfbmode active
C:\>spscmd -getfbmode
Failback : Active
C:\>
In this example, active failback is selected.
/1/ Active failback
Specify "active" or simply "a" as an argument.
/2/ Standby failback
Specify "standby" or simply "s" as an argument
Use the -getfbmode option of the spscmd to check which type of failback has been selected. "Active" will
be displayed if active failback is selected, and "Standby" will be displayed if standby failback is selected.
The -getmode option can also be used to check the same.
C:\>spscmd -getmode
