Subject: dev_loss_tmo behavior question
Date: Tue, 27 Jul 2010 16:11:48 -0500 [thread overview]
Message-ID: <4C4F4B94.1070009@cs.wisc.edu> (raw)
Hi FC driver developers,
I am trying to figure out what is the correct behavior when setting
dev_loss_tmo.
With lpfc, qla2xx, and ibmfc if I set dev_loss_tmo using
/sys/class/fc_remote_port/rport-xx/dev_loss_tmo, and then we add devices
the slave_configure functions for these drivers reset the dev_loss_tmo
to a driver value.
The addition of devs could be from something like a user rescan, or from
a scan started by a remote port addition.
With fcoe, fnic, mptfc, bfa and zfcp the dev_loss_tmo value set from
sysfs will not be reset by a driver value on rescans.
Which drivers should be changed?
