To issue I/O requests of size 1 MB for a Broadcom NVMe/FC host, you must increase the lpfc value of the lpfc_sg_seg_cnt parameter to 256 from the default value of 64. To unload kernel module run time we can use modprobe --remove <module_name> # modprobe --remove -v btrfs rmmod btrfs rmmod xor rmmod raid6_pq. When using EMC storage configured with passive paths, issuing modprobe lpfc without the scsi_dh_emc module loaded fails to complete in a timely manner and leads to numerous scsi errors and soft lockup messages.

I wasn't able to find out the real differences, in practice, between Because the modprobe command can add or remove more than one module, due to modules having dependencies, we need a method of specifying what options are to be used with those modules. options lpfc lpfc_sg_seg_cnt=256 This parameter is valid only when boot_type is set to 1. However, I am unable to change parameters 'on the fly' and have to reboot for changes to take effect. In case of a path loss, the NVMe subsytem tries to reconnect for a time period, defined by the ctrl-loss-tmo option of the nvme connect command. d/ the changes would take effect as soon as I either (a) reloaded the module with modprobe or (b) rebooted.

I've seen, mainly, three ways of blacklisting driver modules by appending parameters to the kernel: (i) modprobe. Set lpfc_enable_fc4_type to 3 to enable SLES12 SP4 as an NVMe/FC initiator. Note that you may need to rescan the scsi devices, depending on your initiator's HBA. Steps Set the lpfc_sg_seg_cnt parameter to 256: Alternatively, use nvme connect-all to connect to all discovered namespaces. In order to prevent kernel modules loading during boot, the module name must be added to a configuration file for the "modprobe" utility. We recommend to create a separate file for the lpfc driver if it doesn't exist Depending on your operating system version, you can modify one or more of the following queue depth parameters: The lpfc_tgt_queue_depth parameter is applicable only for Red Hat Set lpfc_enable_fc4_type to 3 to enable SLES12 SP4 as an NVMe/FC initiator.
