Subject: [SCSI] ses: requesting a fault indication
From: Douglas Gilbert <[email protected]>
commit 2a350cab9daf9a46322d83b091bb05cf54ccf6ab upstream.
Noticed that when the sysfs interface of the SCSI SES
driver was used to request a fault indication the LED
flashed but the buzzer didn't sound. So it was doing
what REQUEST IDENT (locate) should do.
Changelog:
- fix the setting of REQUEST FAULT for the device slot
and array device slot elements in the enclosure control
diagnostic page
- note the potentially defective code that reads the
FAULT SENSED and FAULT REQUESTED bits from the enclosure
status diagnostic page
The attached patch is against git/scsi-misc-2.6
