redundancy

This basetype is used by show redundancy-mode.

Table 1. redundancy properties
Name Type Description
redundancy-mode string The operating mode of the system, also called the cache redundancy mode.
  • Active-Active ULP : Both controllers are active using ULP (Unified LUN Presentation). Data for volumes configured to use write-back cache is automatically mirrored between the two controllers to provide fault tolerance.
  • Single Controller : The enclosure contains a single controller.
  • Failed Over : Operation has failed over to one controller because its partner is not operational. The system has lost redundancy.
  • Down : Both controllers are not operational.
redundancy-mode-numeric uint32 Numeric equivalents for redundancy-modevalues.
  • 8: Active-Active ULP
  • 9: Single Controller
  • 10: Failed Over
  • 11: Down
redundancy-status string
  • Oeprational but not redundant : Both controllers are operational but are not mirroring their cache metadata to each other.
  • Redundant : Both controllers are operational.
  • Operational but not redundant : In active-active mode, one controller is operational and the other is offline. In single-controller mode, the controller is operational.
  • Down : Thi s controller is not operational.
  • Unknown: Status information is not available.
redundancy-status-numeric uint32 Numeric equivalents for redundancy-status values.
  • 0: Operational but not redundant
  • 2: Redundant
  • 4: Down
  • 5: Unknown
controller-a-status string
  • Operational : The controller is operational.
  • Down : The controller is installed but not operational.
  • Not Installed : The controller is not installed.
controller-a-status-numeric uint32 Numeric equivalents for controller-a-status values.
  • 0: Operational
  • 1: Down
  • 2: Not Installed
controller-a-serial-number string
  • Controller module serial number
  • Not Available : The controller is down or not installed.
controller-b-status string
  • Operational : The controller is operational.
  • Down : The controller is installed but not operational.
  • Not Installed : The controller is not installed.
controller-b-status-numeric uint32 Numeric equivalents for controller-b-status values.
  • 0: Operational
  • 1: Down
  • 2: Not Installed
controller-b-serial-number string
  • Controller module serial number
  • Not Available : The controller is down or not installed.
other-MC-status string The operational status of the Management Controller in the partner controller. This is not factored into system health.
  • Operational: The partner Management Controller is responding normally.
  • Not Operational: The local Management Controller has established communication with the partner Management Controller, but the partner is not responding because it is not currently in active-active or failed-over state.
  • Not Communicating: The partner Management Controller is not ready to communicate.
  • Unknown: The operational status of the partner Management Controller cannot be determined.
other-MC-status-numeric uint32 Numeric equivalents for other-mc-status values.
  • 4749: Operational
  • 3231: Not Operational
  • 1524: Not Communicating
  • 1496: Unknown
system-ready string Shows whether the system is ready for running a script.
  • Ready: The system is ready.
  • Not Ready: The system is not ready.

  • 11: Not Ready
local-ready string Shows the local controller's contribution towards system-ready.
  • Ready: The local controller's contribution is ready.
  • Storage Controller is Not Ready: The Storage Controller's contribution is not ready.
  • Management Controller is Not Ready: The Management Controller's contribution is not ready.
  • Activity is currently in progress: A partner firmware update, firmware installation, or log retrieval is in progress. Wait for that operation to complete and try again.
local-ready-numeric uint32 Numeric equivalent for the local-ready value.
  • 0: Ready
  • 1: Storage Controller is Not Ready
  • 2: Management Controller is Not Ready
  • 3: Activity is currently in progress
local-reason string The explanation for the local-ready value.
other-ready string Shows the partner controller's contribution towards system-ready.
  • Ready: The partner controller's contribution is ready.
  • Storage Controller is Not Ready: The Storage Controller's contribution is not ready.
  • Management Controller is Not Ready: The Management Controller's contribution is not ready.
  • Activity is currently in progress: A partner firmware update, firmware installation, or log retrieval is in progress. Wait for that operation to complete and try again.
other-ready-numeric uint32 Numeric equivalent for the other-ready value.
