Fabric OS Commands
Example
This example is for the StorageWorks Core switch:
switch:admin> reboot
Warning: This command is being run on a control processor (CP) based system
and will cause the active CP to reboot. This will cause disruption to devices
attached to both switch 0 and switch 1.
To just reboot a logical switch on this system, use command switchreboot(1M)
on the logical switch you intend to reboot.
Are you sure you want to reboot the active CP [y/n]? y
