Resetting locks in the Symmetrix/VMAX3 storage system

SHC-OSD protects SRDF and TimeFinder actions against simultaneous actions of other tasks or systems by using locks (known as Symmetrix locks).

It may happen that either the global Symmetrix lock for SRDF actions or the individual device locks are set. This is indicated by messages NDE1152 and NDE1153. The name of the system which set the lock cannot be output.

The global Symmetrix locks for SRDF actions are displayed using /SHOW-SYMMETRIX-CONFIGURATION ...,INFORMATION=*LOCKS and reset using /UNLOCK-SYMMETRIX. Global Symmetrix locks are not used for TimeFinder actions.

The device locks are displayed using /SHOW-SYMMETRIX-DEVICE-CONFIG ...,INFORMATION=*LOCKED-DEVICES and reset using /UNLOCK-SYMMETRIX-DEVICE.
