The failed command must empty the virtual disk cache before attempting the requested action to ensure that data is preserved. The empty VDisk cache subtask has taken too long, and therefore the command that you have submitted was not initiated so that other configuration activity can occur.
The system continues attempting to empty the virtual disk cache.
The storage associated with the virtual disk is probably overloaded.
Wait a few minutes to allow the virtual disk cache to empty. Resubmit the command.
Alternatively, you can use the -force parameter, if the command supports the -force parameter, to bypass the empty virtual disk cache subtask. However, specifying the -force parameter will discard cache data for the virtual disk. Only use the -force flag with this command if you do not intend to use the existing contents of the virtual disk.
In addition to the above actions, investigate the performance of the network storage devices associated with this virtual disk. The performance of host applications using these devices might be degraded.
Remedial action to resolve a performance problem enables host application performance to return to optimal conditions, and prevents this error message from recurring when you resubmit the command that caused this error.
