适用场景

  • NetApp E 系列系统。
  • NetApp SANtricity OS
  • 访问 LUN (也称为访问卷)

问题解答

  • 访问 LUN ( UTM LUN ):
    • 默认情况下映射
    • 仅功能是允许带内管理
    • 允许将 SCSI 命令转换为用于 SAN 端口 SANtricity 管理的符号命令
  • UTM LUN 不支持 I/O 操作如果仅对存储进行带外管理,请取消映射访问 LUN "Universal Xport" 。
  • 操作系统多路径驱动程序可以阻止 / 列出 UTM LUN ,以显示读写 I/O 操作。以下是使用设备映射程序多路径驱动程序的 Linux 操作系统示例:
    • 示例:(包括在 /etc/multipath.conf中)

blacklist {
   device {
      vendor "*"
      product "Universal Xport"
   }
}
