Usage Guidelines

  • If the A/A work mode is enabled, the host or gateway installed with Veritas DMP identifies the storage device as the A/A type.
  • If the A/A work mode is disabled, the host or gateway installed with Veritas DMP identifies the single- and dual-controller storage device as the A/A-A type, and identifies the multi-controller storage device as the A/A type.

Example

Change the A/A work mode of a storage device.

developer:/>change tgt_switch storage_work_mode switch=on 
DANGER: You are about to change the A/A work mode of the storage device. If the Veritas DMP software is installed on the host or gateway and the Veritas DMP software takes over LUNs mapped from the storage device, this operation will cause the LUNs to be offline.  
Suggestion: Check whether the Veritas DMP software is installed on the host or gateway connected to the storage device and whether the Veritas DMP software takes over the LUNs mapped from the storage device. If yes, stop services on these LUNs, change the work mode, and restart the host.
