This patch would also help the iscsi LLDD as it is also facing the same START_UNIT problem. I would really appreciate any help on this matter. Thanks, Sachin -----Original Message----- From: linux-scsi-owner@vger.kernel.org [mailto:linux-scsi-owner@vger.kernel.org] On Behalf Of Brian King Sent: Friday, January 30, 2004 3:45 AM To: James.Bottomley@steeleye.com Cc: linux-scsi@vger.kernel.org Subject: [PATCH] Midlayer initiated START_UNIT James, This is a patch to issue a START_UNIT command from the midlayer error handler. The ipr driver, which is currently out for review needs this to function properly. Any time the adapter gets reset, the disk array resources under the ipr adapter require another START_UNIT command. This causes problems with the current error handling and these devices get taken offline when this occurs. This was being handled by the ipr driver itself, but Christoph did not like seeing a LLDD issuing commands to devices, hence the patch. http://marc.theaimsgroup.com/?l=linux-scsi&m=107462193622673&w=2 Patch is against 2.6.2-rc2.
