为什么 snmpget OID .1.3.6.1.4.1.789.1.2.2.25.0 在非备用磁盘配置中返回不同的结果？
适用场景
ONTAP 9
问题描述
- snmpget OID
.1.3.6.1.4.1.789.1.2.2.25.0从具有相同非备用配置的不同 HA 系统返回不同的结果： CRIT:GLOBALTATUS nonCritical 4 There are no enough spare disks.OK: GLOBALSTATUS ok 3 The system's global status is normal. | globalstatus=3- 两个系统的配置都与集群级别没有备用磁盘的配置相同。
- 在这种情况下，节点 01 的所有聚合都会保持运行 P1/P2 或整个磁盘，但节点 01 的备用池中只有 P2 个磁盘，该备用池设置为 no-spare 配置：

- 仅运行 P2 磁盘的节点 02 和节点 02 的所有聚合的备用池中都有备用磁盘，这不是无备用配置：
