适用于

  • NetApp E-Series EF300
  • 10/25GbE iSCSI 主机接口卡(HIC)
    • 部件号:110-00611
    • 替换部件号 X-56040-00 和 SP-56040-00

问题

  • 使用 10/25GbE iSCSI 主机接口卡的 E-Series 控制器可能会在不同的 iSCSI HIC 端口上报告相同的 MAC 地址。
  • HIC 上的标签显示了正确的起始 MAC 地址。该地址是 16 个连续地址中的第一个。但是,端口可能会显示重复的出厂默认地址。
  • 当两个受影响的 HIC 连接到同一个网络时,重复的地址可能会导致:
    • 网络连接问题
    • 不正确的流量路由
    • 数据包丢失
    • MAC 地址冲突
    • 间歇性 iSCSI 连接或 iSCSI 登录失败
    • 不稳定的主机路径或多路径错误
    • 网络拦截或抑制其中一个设备
  • 检查 SANtricity 或存储阵列配置文件中 iSCSI 端口上的 MAC 地址。将它们与 HIC 标签上打印的地址进行比较。
