* [SCSI] qla4xxx: Remove reduandant code after open-iscsi integration.Manish Rangankar2011-08-276-838/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1. Remove device database entry (ddb) state. 2. Remove device database (DDB) list building. With open-iscsi integration the logins to the target devices are handled by the user space. So the information of target is now maintained in the iscsi_session object. This is handled at libiscsi level so there is no need to maintain a list of DDBs in the qla4xxx LLD. 3. qla4xxx: Remove add_device_dynamically. Since autologin in FW is disabled with open-iscsi integration, driver will never get an AEN for which driver has not requested a DDB index. So remove the add_device_dynamically function. 4. Remove qla4xxx_tgt_dscvr Since firmware autologin is disabled this function will not work. Now user has the ability to do the target discovery and login to each target individually. Firwmare will not do the login on its own. 5. Remove relogin related code All relogin is handled by userspace now. qla4xxx just need to notify userspace of a connection failure, this triggers the relogin. 6. Remove add_session and alloc_session Now qla4xxx uses iscsi_session_setup that would do the necessary allocations for session and ddb_entry.

* [SCSI] qla4xxx: support iscsiadm session mgmtManish Rangankar2011-08-278-365/+1416
| | | | | | | | | | | | | | | | | | | | | | | | Add scsi_transport_iscsi hooks in qla4xxx to support iSCSI session management using iscsiadm. This patch is based on discussion here http://groups.google.com/group/open-iscsi/browse_thread/thread/e89fd888baf656a0# Now users can use iscsiadm to do target discovery and do login/logout to individual targets using the qla4xxx iSCSI class interface. This patch leaves some dead code, but to make it easier to review we are leaving and in the next patch we will remove that old code. V2 - NOTE: Added code to avoid waiting for AEN during login/logout in the driver, instead added a kernel to user event to notify iscsid about login status. Because of this iscsid will not get blocked.

| | | | | | | | | | | | | | | | | support offload session login. Offload drivers like qla4xxx will offload the sending of the login/logout pdus still, so this patch adds iscsi_conn_login_event which is used by these types of drivers to notify userspace that the connection has changed state. It also adds a iscsi_is_session_online helper so the lld can query the sessions state field.

* [SCSI] ipr: Always initiate hard reset in kdump kernelAnton Blanchard2011-08-271-1/+1
| | | | | | | | | | | | | | | | During kdump testing I noticed timeouts when initialising each IPR adapter. While the driver has logic to detect an adapter in an indeterminate state, it wasn't triggering and each adapter went through a 5 minute timeout before finally going operational. Some analysis showed the needs_hard_reset flag wasn't getting set. We can check the reset_devices kernel parameter which is set by kdump and force a full reset. This fixes the problem.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [Resend patch as per Bernd Schubert comment ] Issue: Device goes offline while doing aggressive HBA reset along with IO using some utility. Root cause: FW goes into bad state due to aggressive reset. Softreset does not help to recover FW. And also aggressive reset open up the window for Error handling thread to kicked off at the same time HBA will be in constant RESET loop as part of aggressive reset test case can lead Device to goes offline. Changes: 1. Added extra check as below inside eh_timed_out call back as below. if(ioc->ioc_reset_in_progress) Rc = EH_TIMER_RESET 2. Removed " DOORBELL_ACTIVE" check for SAS controller from task management context. Since SAS controller uses high priority queue for task management. This check is not required for SAS controller. 3. Moved SoftReset call to HardReset from Task Mgmt context. Signed-off-by: Kashyap Desai <kashyap.desai@lsi.com> Signed-off-by: James Bottomley <JBottomley@Parallels.com>
