Explanation
The unmapping command has not been run because
the system has determined that I/O have been received within the system
defined protection period. This generally indicates that the volume
is in use.
User Response
- Make sure this volume is intended to be unmapped. If the wrong
one was selected, repeat the command with the correct volume.
- Otherwise, if you are sure that you want to unmap this volume,
wait the time that is specified in the vdisk_protection_time field
(see Issystem), and retry the command.
- Alternatively, if you don't want to have volume protection warnings,
then you can disable the vdisk_protection-enabled field by using chsystem.
