@@ -398,6 +398,16 @@ Module scst supports the following parameters:
to be consumed by all SCSI commands of a device at any given time. By
default, it is approximately 2/5 of scst_max_cmd_mem.
- auto_cm_assignment - enables the copy managers auto registration.
If a device is not registered in the copy manager, it can not be
source or target of EXTENDED COPY commands. Enabled by default.
Disable, if you want to manually control the copy manager
registration or need to change a device, e.g. a DM cache device, with
SCST LUN on top of it to avoid extra reference the copy manager holds
on this device. In the later case you can also remove this reference
by manually deleting the corresponding copy manager LUN via sysfs interface
(/sys/kernel/scst_tgt/targets/copy_manager/copy_manager_tgt/luns/mgmt).
