适用场景

  • FAS62xx
  • FAS80xx
  • AFF8080
  • 主板更换
  • NVRAM 更换
  • 未分区的驱动器

问题描述

  • 由于接管节点上的 HA 互连端口关闭而未找到根卷,因此无法执行交还。
WARNING: there do not appear to be any disks attached to the system. No root volume found. Rebooting... (press ctrl-c during boot to break reboot loop)
  • 互连链路在接管节点上关闭,则 NVRAM 卡可能会在接管节点上处于挂起状态。 
  • 控制器 IOXM ( CI )设置中,物理端口两端均显示为 down ( loopback 表示卡上的两个互连链路均已关闭)。

 

  • 接管后,您可能会从接管节点上的 EMS 收到以下消息

  • 尝试执行交还时,接管节点会将配对节点显示为正在等待交还:


示例:

7- 模式:(配对节点正在接管,但未显示 Waiting for Giveback ):

n2(takeover)> cf status
n1 has taken over n2.

集群模式


n2
               n1  false    In takeover
              
n1
               n2  -       Unknown
 <-- 应 " 正在等待交还 "

  • 检查互连时,请注意此互连已关闭

7-模式:

n2*> ic status
        Link 0: down
        Link 1: down
        IC RDMA connection : down

 

集群模式


cluster::*> storage failover interconnect show-link local
Node          Port Number      Link State
------------------------------------------------------------------------------
n2
              0               down
              1               down
2 entries were displayed.

 

 

  • 在物理上,如果控制器采用控制器 -IOXM ( CI )设置,则物理 HA 互连链路将不显示链路指示灯。如果在故障节点等待交还时在 HA 互连端口上进行环路(使用缆线从端口 0 到同一控制器上的端口 1 ),则故障控制器上会亮起,但接管节点上不会亮起。

 

  • 尝试手动启动互连端口,但收到以下错误


7-模式:


n2(takeover)*> ic link on 0
Error: Failed to perform requested operation on port 0 due to an internal error.
The port has been disabled. To re-enable the port, reboot the system.


 

集群模式


cluster::*> interconnect link on -node n2 -link 0
  (system ha interconnect link on)
Error: command failed: Failed to perform requested operation on link 0 due to
       an internal error. The port has been disabled. To re-enable the port,
       reboot the system.

 

  • 如果在接管节点上发现上述错误,则 NVRAM 卡可能会进入挂起状态。
