我们有HP DL-360-g9带有 Raid 控制器的服务器HP240，目前我们总共安装了 4 个磁盘，其中 2 个（镜像）用于操作系统，LVM 组中有 2 个（1TB）单独磁盘。现在我们的存储空间不足，决定添加更多磁盘，因此我们在服务器中添加了 2x1TB 磁盘，但它们现在显示在 Linux CentOS7 中fdisk -l。我们做了以下
echo "- - -" > /sys/class/scsi_host/host0/scan
在 /var/log/messages 中看到
[16507042.745884] scsi 0:0:0:0: lun4194304 has a LUN larger than allowed by the host adapter
[16507042.745892] scsi 0:0:0:0: lun4194560 has a LUN larger than allowed by the host adapter
[16507042.745895] scsi 0:0:0:0: lun4194816 has a LUN larger than allowed by the host adapter
这是scsi

为什么我的磁盘显示非常大的LUN数字，我应该在 modprobe.conf 中设置max_lun=xxxxxx以增加其数字？
或者我应该告诉 RAID 控制器处理磁盘而不是操作系统？
