Subject: fibre channel sync cache question
Date: Tue, 25 Jul 2006 17:22:28 -0500 [thread overview]
Message-ID: <44C699A4.3030409@sgi.com> (raw)
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
