IBM Storwize V3700 T3 Recovery SYMPTOMS IBM V3700 存储，两个节点容器均处于服务状态，578 错误码。检查无其它硬件故障，因此考虑进行 T3 恢复。 T3 恢复有数据丢失风险，操作需谨慎！！！ PROCEDURE 使用 HUB 或傻瓜交换机将两个节点容器和 PC 工作站互联。 【管理系统】-【除去系统数据】，使得两个节点容器状态均处于候选。 【恢复系统】-【准备恢复】，系统自动搜索备份数据。 【恢复】 恢复过程中，界面失去响应无法访问，应该是节点容器 1 异常重启导致（原先节点容器 1 有无故重启问题）。查看服务助手，两个节点容器均为活动状态，节点 2 有 724 错误码（活动网口未连接）。 虽然重新组成了群集，但是登录管理 GUI 出现初始化界面（此时不要进行初始化流程操作），说明 T3 恢复失败。 所以考虑再次进行 T3 恢复。 将两个节点容器设为服务状态，重新清除系统数据。 清除后状态没有变为候选，此时 SSH 登录节点容器，将节点容器退出群集。 重启节点容器后，重新变为...
