Unloading the FCP driver using the modprobe -r command might cause issues on the initiator before NVMe devices are disconnected. I created the following file in /etc/modprobe. After the elx_lpfc_install. You need to set corrcet vaules. dracut 053 ONTAP reports an MDTS (Max Data Transfer Size) of 8 in the Identify Controller data. Enable the lpfc_enable_mds_diags parameter temporarily by issuing the following commands: rmmod lpfc modprobe lpfc lpfc_enable_mds_diags=1 After the diagnostics are complete, reload the driver without the lpfc_enable_mds_diags parameter. In case of a path loss, the NVMe subsystem tries to reconnect for a time period, defined by the ctrl-loss-tmo option of the nvme connect command. If a fan-out configuration is used, where an HPE Alletra 9000 storage system port is connected to many hosts through a fabric, it is possible that the target port will run out of I/O buffers and will result in the target port issuing a QUEUE FULL SCSI status message to any new incoming I/O Update the queue depths by adding the queue depth parameter to the /etc/modprobe. Modprobe tries to remove the module with an incremental sleep time between each tentative up until the maximum wait time in milliseconds passed in this Add or edit the /etc/modprobe. The NVMe over Fibre Channel (FC-NVMe) is fully supported in initiator mode when used with certain Broadcom Emulex and Marvell Qlogic Fibre Channel lpfc_use_msi=0 to be able to use these adapters. The Oracle Linux 7. 1 By default, the modprobe command adds a module. I'm guessing this is the case due to mkinitrd not using the lpfc_topology option (to options lpfc lpfc_nodev_tmo=14 lpfc_lun_queue_depth=16 lpfc_discovery_threads=32 In SLES 9 hosts, edit the /etc/modprobe.
