FlexArray 后端 LUN 显示状态失败
适用场景
- ONTAP 9
- FlexArray
问题描述
- FlexArray后端LUN的状态显示为 故障。
- 后端阵列将LUN显示为已启动。
- 在这种情况下、执行自动无中断升级(ANDU)会导致其暂停：

Node01 failed Error: Takeover failed.
Action: Use the "storage failover
show-takeover" command to view the
cause of takeover failure and the
suggested corrective actions. When
all issues are resolved, use the
"storage failover takeover -ofnode
Node01" command to trigger
takeover.

Optimized takeover

aggr1_data Failed: Destination node did
not online the aggregate on
time. To abort the takeover,
you can giveback the
aggregates that were relocated
as part of the attempted
takeover using the "storage
failover giveback -ofnode
Node01" command. If
you want to continue the
takeover, address the failures
and then use the "storage
failover takeover -ofnode
Node01" command. If
you want to continue with the
takeover without addressing
the failures you can do so by
using the "storage failover
takeover -ofnode
Node01
-bypass-optimization true"
command. Warning: Setting the
"-bypass-optimization"
parameter to true will result
in a longer overall client
outage during manual takeover
events on a cluster system.
