我们已经建立了光纤通道，我想连接到它（顺便说一下，我在使用 Ubuntu 12.04）。
我可以看到已交付的 wwpn。但我不知道接下来该做什么。我可以 fdisk 到 /dev 驱动器，但一旦我尝试通过 mkefs 在其上创建文件系统，就会收到 ioctl 错误。
以下是我展示的内容：
systool -c fc_host -A“port_name”给我
Class = "fc_host"
Class Device = "host5"
port_name = "0x21000024ff274080"
Device = "host5"
Class Device = "host6"
port_name = "0x21000024ff274081"
Device = "host6"
Class Device = "host7"
port_name = "0x21000024ff27411a"
Device = "host7"
Class Device = "host8"
port_name = "0x21000024ff27411b"
Device = "host8"
当我执行 ls -ltra /dev/mapper 时，我看到

ls /sys/class/fc_host 显示 host5、host6、host7 和 host8。
lsscsi 显示我的驱动器：

我可以通过 fdisk 转到 /dev/sdd，并正确创建一个分区。
但是当我尝试执行 mke2fs -t ext4 -m 0 -O dir_index /dev/sdd1 之类的操作时，它告诉我“/dev/sdd1 显然正在被系统使用；不会在这里创建文件系统！”
有什么线索吗？
