我有“multipath -ll”命令的输出

来自 RHEL：

mpath114 (3600507680283095ea8000000000004fa) dm-28 IBM,2145
[size=200G][features=1 queue_if_no_path][hwhandler=0][rw]

 \_ 20:0:0:1  sdk  8:160   [active][ready]

或从 SLES 服务器：

mpathmzp (36005076801c7061ef800000000000089) dm-0 IBM,2145
size=10G features='1 queue_if_no_path' hwhandler='0' wp=rw
|-+- policy='round-robin 0' prio=50 status=enabled
| `- 67:0:2:0 sde 8:64 active ready running
| `- 68:0:0:1 sdl 8:76 failed faulty running
`-+- policy='round-robin 0' prio=10 status=enabled
  |- 67:0:3:0 sdc 8:32 active ready running
  `- 68:0:0:0 sdd 8:48 active ready running
[..]

我想解析它（最好使用 awk 或 bash），以显示配置摘要。它应该打印伪多路径设备和活动路径的数量以及失败的（如果有的话）样本：

dm-39, 10G,  Total: 4 paths, active: 4, failed: 0
dm-28, 200G, Total: 5 paths, active: 4, failed: 1

SLES 也一样：

dm-0,  10G,  Total: 4 paths, active: 3, failed: 1

如果也可能的话，我想对输出进行排序，以使没有失败和大多数活动路径的路径位于顶部，并以具有失败路径的设备结束。

感谢您的帮助！

这awk应该这样做：

multipath -ll | awk 'NR>1 {r=f=0;for (i=1;i<=NF;i++) if ($i~/ready/) r++; else if ($i~/faulty/) f++;split($5,a,"=|]");print $3,a[2]"\tTotal: "r+f" paths, active: "r,"failed: "f}' RS="mpath" OFS=", "
dm-28, 200G     Total: 5 paths, active: 4, failed: 1
dm-39, 10G      Total: 4 paths, active: 4, failed: 0
