This brings up something else ‘interesting’ I just ran into again.
I have an Agilent Tachyon HBA with a JBOD with 4 drives attached to it.
Sometimes the 4 drives disappear. I can not make them reappear with any
IOCTLs or even by disabling/re-enabling the HBA. As an ultimate rescue I
have to disconnect the cable and reconnect it. Only then will the drives
show up. It takes quite a while for this to complete and I can hear the
drives spin up one by one.
Does anyone here have a bullit proof method to get the drives attached to an
HBA to show up? There is no switch involved in this case, just a directly
attached loop.
I’m using an HHBA-512x PCI with 3.1.8.13 drivers. I’ve only seen this on the
Agilent cards so far, Qlogic ones can be reset by disabling and re-enabling.
Thanks,
Sander

Subject: [ntdev] RE: Breaking SCSI Reservation on Fiber channel
environmen tsThe questions the fibre HBA vendors have had to ask themselves are,
what “bus” do you wish to reset? and what do you mean by “reset”?Check the HBA vendor’s driver’s docs to see if they have registry
settings that determine what they do to the SAN when you ask
for reset.
