SCF Reference Manual for the Storage Subsystem (G06.28+, H06.05+, J06.03+)

PRIMARY Command Function in G06.00 Through G06.10
On G05.00 through G06.10, the PRIMARY command changes processor ownership of active
paths. (The FORCED option forces all SACs to change ownership.) This change in ownership in
turn causes other IOPs in the same topology branch to perform additional path switches or processor
swaps to recover from the loss of SAC ownership.
