zfs discuss - Sep 2011 - Scrubbing with faulted disk still physically attached

Hi,

We''ve got faulted disk in ZFS mirror and hot spare active.

Any experience of scrubbing in such scenario causing problems,
since the faulted disk is still attached.
We have been scrubbing all our pools once a week (heh, might be quite too
often?)
No scrub has taken place since the disk faulted on 6th of September and SMF
activated hot spare.

Faulted disk has been causing scsi bus resets during couple few days
and we are unable to replace the disk for a week or so.
Just wondering if the scrubbing could cause the faulted disk to screw up the
SCSI bus
because of IO heavy operations going on.
As you can see our mirror can tolerate the other SCSI controller going down:
