214

Informational The creation of snapshots is complete. The 

number of snapshots is specified.

215

Informational A previously created batch of snapshots is 

now committed and ready for use. The 

number of snapshots is specified.

217

Critical

A super-capacitor failure has occurred on the 

controller.

A service technician must replace the 

super-capacitor pack on the controller 

reporting this event.

218

Warning

The super-capacitor pack is near end of life.

A service technician must replace the 

super-capacitor pack on the controller 

reporting this event.

219

Informational Utility priority has changed. 

220

Informational Master volume rollback operation has 

started.

221

Informational Snapshot reset is completed.

222

Informational Setting of the policy for the snap pool is 

complete. Policy is the action to be taken 

when the snap pool hits the threshold level.

223

Informational The threshold level for the snap pool has 

been set. Each snap pool has three policy 

levels that notify you when the snap pool is 

reaching decreasing capacity. Each policy 

level has an associated policy that specifies 

system behavior when the threshold is 

reached.

224

Informational A background master volume rollback 

operation has completed.

225

Critical

Background master write copy-on-write 

operation has failed. 
There was an internal I/O error. Could not 

complete the write operation to the disk.

A probable hardware failure has prevented 

the software from operating successfully. 

Isolate and replace and failed hardware 

components. Once the hardware issues have 

been corrected, it might be necessary to 

delete all snapshots and restart the 

controller.

226

Critical

A background master volume rollback failed 

to start due to inability to initialize the snap 

pool. All rollback is in a suspended state. 

Make sure the snap pool and the vdisk on 

which this volume exists are online. Restart 

the rollback operation.

227

Critical

Failure to execute rollback for a particular 

portion of the master volume. 

Restart the rollback operation.

228

Critical

Background rollback for a master volume 

failed to end due to inability to initialize the 

snap pool. All rollback is in a suspended 

state.

Make sure the snap pool and the vdisk on 

which this volume exists are online. Restart 

the rollback operation.

229

Warning

The snap pool has reached the snap pool 

warning threshold.

The user can set up the policy for the snap 

pool.
