fibre channel sync cache question

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello All,

Using fibre channel disks, I've noticed that when the system shuts down
that the sd_driver issues a sync cache command to the device.  I've also
noticed that when the lldd is removed via rmmod that this sync cache is
not executed.  I would think that the sync cache would be desirable
under this circumstance.

Was it a conscious decision to not have sync cache executed during
module unload?

Is it desirable?

(There are various reasons why it doesn't work.  The rport port_state
is not ONLINE, the module is being unloaded so that a reference cannot
be acquired, the sdev state is SDEV_CANCEL.  Three strikes and you're
out?)


Mike
