Symptoms
配置了新的辅助网络（例如复制网络）的客户注意到其接口也用于 iSCSI 存储。
移除/删除该网络的选项将呈灰显，因此无法删除。
Cause
按照设计原意，所有存储相关 IP 协议都使用存储网络资源。
在当前的 Powerstore 实现中，其用途不可分隔。
Resolution
此问题被视为“设计意图”并记录在复制指南中：
在使用默认配置规划复制时，请考虑到端口也用于其他流量，例如 iSCSI 主机访问、迁移和文件的 I/O（仅限 PowerStore T 型号）。如果使用这些功能，建议使用专用接口规划复制。额外端口使用 ICW 中提供的或在 PowerStore Manager 的网络部分中添加的范围内的动态存储 IP 配置。

请注意，pstcli 也不提供任何删除网络的选项，因为它被标记为正在使用中。
