The intent of this patch is to perform a graceful shutdown of target drives even if volume doesn't exits. Changes done in this patch
1. Removed the check for the presence of volumes before sending down MPI2_RAID_ACTION_SYSTEM_SHUTDOWN_INITIATED. Therefore, this RAID action would be sent if the card is IR Firmware. 2. The MPI2_RAID_ACTION_SYSTEM_SHUTDOWN_INITIATED is sent even when the system undergoes suspend (in addition to remove/shutdown which was already present) Signed-off-by: Sreekanth Reddy <[email protected]> --- drivers/scsi/mpt2sas/mpt2sas_scsih.c | 5 +---- 1 files changed, 1 insertions(+), 4 deletions(-) diff --git a/drivers/scsi/mpt2sas/mpt2sas_scsih.c b/drivers/scsi/mpt2sas/mpt2sas_scsih.c index 344db2e..75e6812 100644 --- a/drivers/scsi/mpt2sas/mpt2sas_scsih.c +++ b/drivers/scsi/mpt2sas/mpt2sas_scsih.c @@ -7710,10 +7710,6 @@ _scsih_ir_shutdown(struct MPT2SAS_ADAPTER *ioc) if (!ioc->ir_firmware) return; - /* are there any volumes ? */ - if (list_empty(&ioc->raid_device_list)) - return; - mutex_lock(&ioc->scsih_cmds.mutex); if (ioc->scsih_cmds.status != MPT2_CMD_NOT_USED) { @@ -8279,6 +8275,7 @@ _scsih_suspend(struct pci_dev *pdev, pm_message_t state) mpt2sas_base_stop_watchdog(ioc); scsi_block_requests(shost); + _scsih_ir_shutdown(ioc); device_state = pci_choose_state(pdev, state); printk(MPT2SAS_INFO_FMT "pdev=0x%p, slot=%s, entering " "operating state [D%d]\n", ioc->name, pdev, -- 1.7.3 -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
