Resetting All Cache and NVS Operating States to Defaults

SETCACHE REINITIALIZE performs the following:
  • Resets all Storage Control cache and NVS operating states to the initial installation subsystem defaults (in addition all status tracks are reinitialized).
  • Resets all status information to default state.
  • Discards all modified tracks in the cache or NVS. All dual copy logical volumes are set to simplex state and all dual copy logical volumes are reset to simplex. To save the modified data, issue SETCACHE DESTAGE before issuing SETCACHE REINITIALIZE.

Because of the nature of this command, all volumes in the subsystem must be varied offline to all attached system images before the command is issued.

Attention: Carefully consider the use of SETCACHE REINITIALIZE before issuing the command and ensure that all data has been destaged to DASD. This command resets all dual copy logical pairs to simplex state and resets the CCA/DDC pointers to their original state.
