Example:
# spmt toggle – t 2
spmt restart/spmt shutdown
The spmt restart and spmt shutdown commands cause I/O to be redirected to
the other controller. The spmt restart command will function if multiple hosts
are actively accessing LUNs. Therefore, if Secure Path is active on those
hosts, I/O will be properly transferred to alternate paths.
The difference between restart and shutdown is that restart will cause the
controller to reboot, while shutdown will stop the controller.
The purpose of these two commands is to move all online LUNs from the
specified controller to the other controller. This allows the user to perform
maintenance operations on the specified controller.
These commands have the form:
# spmt restart -c serial_number
# spmt shutdown -c serial_number
where:
serial_number
specifies the RAID controller to be taken offline.
Examples:
# spmt restart – c ZG92810158
# spmt shutdown – c ZG92810158
spmt remove
The spmt remove command quiecses the path for a specified host adapter
adapter. All I/O is redirected to the other path and the removed path is marked
quiesced. This also disables the path for future I/O until a spmt reconfig is
issued.
The spmt remove
command has the form:
# spmt remove -a hba
where:
hba
refers to the instance of the Solaris host bus adapter
