IOCTL_STORAGE_RESET_BUS doesn't clear SCSI Reservations. |
|

Hi,
I am trying to use IOCTL_STORAGE_RESET_BUS.
I have a set up where two Windows Machines are sharing a library over
SAN (using Brocade silkworm 2400 switch). One of the machines is
windows 2003 server and other is windows 2000 server.
IOCTL_STORAGE_RESET_BUS actually works on W2K3 machine (HBA is Emulex
LightPulse 9000) and it clears all Previous SCSI Reservations (done
using SCSI command 0x16) on the drives in the library and I could see
Event in Windows Event Viewer saying that SCSI bus has been reset on
request. I could then reserve the same drive from another machine.
Problem is that IOCTL_STORAGE_RESET_BUS on W2K machine returns success
but (this one is Q-Logic QLA2340 HBA) it doesn't clear previous
reservations made on drives. I see event in windows event viewer after
that saying that "The device, \Device\Scsi\xxxxxxx, did not respond
within the timeout period."
I enabled options to allow Target Device Reset from QLogic Bios
Configuration Utility-Advanced Adapter Options but that didn't help.
On w2k3 system, I tried it with both Scsiport-Miniport and
Storport-miniport drivers and it worked and clears reservations. But on
w2k system it doesn't clear the SCSI reservation.
Anyone has any Idea why this might be happening?
Any help on this will be really appreciated.
Thanks and Regards.
Hetal. |
