CMMVC8461E: The host cannot be removed because the host being deleted is mapped to volumes which have received I/O within the defined volume protection period.

Explanation

If volume protection is enabled, and the host being deleted is mapped to any volume which has received I/O within the defined volume protection time period, then the command will fail.

This behaviour is not affected by the force flag (the force flag deletes the host even if it has any vdisk mappings). For example, the force flag does not override the policing.

If multiple hosts are mapped to the same volume, then the command will be allowed if the host that is being removed is already 'offline'. The protection will still prevent the last host being removed regardless of whether it is online or not (This is an effort to improve the policing behaviour for clustered hosts).

User Response

Ensure no host I/O is being sent to the volumes mapped to the host and ensure you have waited for the defined volume protection time period or disable volume protection.
