From 3a9c913a3e57b170887d39456e04c18f2305ec67 Mon Sep 17 00:00:00 2001 From: "Kashyap, Desai" Date: Tue, 4 Jan 2011 11:40:23 +0530 Subject: [SCSI] mpt2sas: fix Integrated Raid unsynced on shutdown problem Issue: IR shutdown(sending) and IR shutdown(complete) messages not listed in /var/log/messages when driver is removed. The driver needs to issue a MPI2_RAID_ACTION_SYSTEM_SHUTDOWN_INITIATED request when the driver is unloaded so the IR metadata journal is updated. If this request is not sent, then the volume would need a "check consistency" issued on the next bootup if the volume was roamed from one initiator to another. The current driver supports this feature only when the system is rebooted, however this also need to be supported if the driver is unloaded Fix: To fix this issue, the driver is going to need to call the _scsih_ir_shutdown prior to reporting the volumes missing from the OS, hence the device handles are still present.
