通过shell脚本删除断开连接的LUN (regex问题)

Question

我的脚本有问题，不想在更改LUN号的情况下运行相同的过程200次。从LUN的所有路径中删除多径设备，运行echo 1 > /sys/bus/scsi/devices/${H:B:T:L}/delete (其中H=主机:B= bus:T = target:L = lun)，例如2:0:3:1到2:0:3:49

让我们检查一下我们的月球：

[2:0:3:33]   disk    NETAPP   LUN C-Mode       9700  /dev/sdbt
[2:0:3:34]   disk    NETAPP   LUN C-Mode       9700  /dev/sdbv
[2:0:3:35]   disk    NETAPP   LUN C-Mode       9700  /dev/sdbw
[2:0:3:36]   disk    NETAPP   LUN C-Mode       9700  /dev/sdby
[2:0:3:37]   disk    NETAPP   LUN C-Mode       9700  /dev/sdca
[2:0:3:38]   disk    NETAPP   LUN C-Mode       9700  /dev/sdcc
[2:0:3:39]   disk    NETAPP   LUN C-Mode       9700  /dev/sdce
[2:0:3:40]   disk    NETAPP   LUN C-Mode       9700  /dev/sdcg
[2:0:3:41]   disk    NETAPP   LUN C-Mode       9700  /dev/sdci
[2:0:3:42]   disk    NETAPP   LUN C-Mode       9700  /dev/sdck
[2:0:3:43]   disk    NETAPP   LUN C-Mode       9700  /dev/sdcm
[2:0:3:44]   disk    NETAPP   LUN C-Mode       9700  /dev/sdco
[2:0:3:45]   disk    NETAPP   LUN C-Mode       9700  /dev/sdcp

清理脚本：

for IP in {1...45} ; do 'echo 1 > /sys/bus/scsi/devices/2:0:3:$IP/delete'; done

获取错误：

-bash: echo 1 > /sys/bus/scsi/devices/2:0:3:$IP/delete: No such file or directory

另一次尝试：

for IP in {1...45} ; do "echo 1 > /sys/bus/scsi/devices/2:0:3:$IP/delete"; done

获取错误：

-bash: echo 1 > /sys/bus/scsi/devices/2:0:3:{1...45}/delete: No such file or directory

如何隔离$IP使其在该请求中工作？

您有{1...45}，但语法似乎是{1..45}。https://www.gnu.org/savannah-checkouts/gnu/bash/manual/bash.html#Brace-Expansion
