适用场景

  • ONTAP 9
  • 控制器硬件升级
    • HeadSwap
    • 机头升级
  • AFF 系统
  • FAS 系统
  • MetroCluster
  • 安装了FlexArray虚拟化软件的系统

描述

本指南介绍如何通过移动存储或卷来升级集群中AFF系统或FAS系统的控制器硬件。

  • 在ONTAP 9.8中、引入了自动端口放置功能、从而简化了硬件升级过程。
  • 在升级运行ONTAP 9.8及更高版本的系统时、请使用正确的操作步骤来说明端口放置功能。
升级过程

查看下表以查看可用的升级过程。有关其他详细信息、请参见每个指南、以确定操作步骤是否合适。

硬件升级方法
 位置
通过在运行ONTAP 9.8或更高版本的系统上移动聚合进行升级
通过在运行ONTAP 9.7或更早版本的系统上移动聚合进行升级
通过移动存储或卷进行升级(大多数系统)

 

解决方案指南

查看下表、了解升级期间可能出现的已知问题： 

已知问题 解决方法
兼容性问题

控制器更换操作不支持节点"NODE_NAME"的控制器型号
FAS8300不支持在任何板载端口上使用10GbE链路
在机头升级期间、新的FAS或AFF控制器启动时ONTAP版本不正确
网络配置问题
Cannot run this command because the system is not fully initialized.
  • network interface show 输出中缺少集群LUN
  • vserver show 输出中缺少集群SVM
  • 在此状态下、如果尝试使用将集群 network interface migrate 迁移到新平台端口 、则会出现错误：

Error: command failed: LIF "node1_clus1" on Vserver "Cluster" could not be found in database (database vifids is not open). Contact technical support for assistance.
Error: command failed: Cannot remove port that is a failover target for a LIF. To list LIFs containing a failover target, use the "network interface show -failover-targets <targetname>" command.
FAS8300 机头交换后HA互连关闭

 使用无中断聚合重新定位(ARL) 操作步骤或移动存储中断操作步骤进行升级

  • FAS8200至FAS8300.
  • AFF A300至AFF A400
故障转移问题

升级控制器后无法接管

Takeover is not possible: Storage failover mailbox disk state is invalid, Storage failover is disabled on the partner node, Storage failover interconnect error, NVRAM log not synchronized, Disk inventory not exchanged
正在尝试向使用CN1610集群网络交换机的现有集群添加2个新AFF A250节点。
