Symptoms
在 PowerFlex 存储上托管的 Windows 2012 R2 虚拟机上运行的 PowerFlex SDC 驱动程序加载缓慢,最后挂起并且无法访问映射到它的卷。
症状
运行 ping 命令无法成功完成从 Windows SDC 到其中一个 SDS 节点的运行。
Windows 服务器的系统事件日志显示磁盘问题,例如:

(The request failed due to a fatal device hardware error.) 03/15/2017 12:48:50 AM Error PDC04OPFTPGL01.h 55 Ntfs A corruption was discovered in the file system structure on volume D:. The exact nature of the corruption is unknown. The file system structures need to be scanned online.
冲击
主机变得缓慢且无响应。对 SDC 的已分配卷的访问丢失。
Cause
环境中的防火墙规则进行了更改。一个 SDS 节点不在防火墙规则集中,导致 SDC 失去对已分配卷的访问权限。
Resolution
重新获得卷访问权限的最快方法是将有防火墙的 SDS 置于维护模式。仅当仅影响一个故障集时才适用(正常维护模式规则适用)
更正防火墙规则,将 PowerFlex SDS 节点重新添加到规则中。确保端口 7072 处于打开状态,并且未被任何其他应用程序使用。
使用 ping/telnet 进行测试,以确认已应用防火墙规则,以及将 SDS 退出维护模式是安全的。
