请问什么是The gatekeeper device

symdev命令不成功？你到STORAPID daemon log里面看看有没有什么报错，然后贴出来大家看看吧。

/var/symapi/storapid.log

控制信息流不是在存储的cache中的呀。

不好意思 想问 如果 被选中的gatekeeper的盘 是不是同时在做存储数据和存储转发控制信息的双重职责呢？

如Alex所说。Gatekeeper设备仅仅用来处理读写磁盘设备的SCSI指令。

Solutions Enabler软件会自动选择最小的LUN作为Gatekeeper设备。

如果没有给一个安装了Solutions Enabler软件的服务器分配特定的Gatekeeper设备，那么存放数据的LUN也会被SE选中作为Gatekeeper设备来使用。这样的情况对某些应用对这些LUN的访问会造成影响。

因此，EMC要求对于每一个SE主机分配至少5个（有些文档里面会说6个）大小为2880 KB的设备，这样SE会选择它们作为GK，并且这些设备上也不会存放数据。

请教各位前辈偶查看了日志是这样的。把symmetrix ID给替代啦。

是不是什么东西坏了？

就听楼上的，如果不是什么东西损坏了是否可以不管呢？

ioscan -fnCdisk 看过了标记为GK的LUN都是CLAIMED的。。

从日志看上去，是这台服务器到某个Symm的连接有问题，体现在从这个阵列分过来的GK都无法访问了。

可以尝试运行一下symcfg discover，然后看看symcfg list还能不能列出这个阵列，并且查看一下这些报错的设备在ioscan -fnkC disk中是CLAIMED还是NO_HW状态。（看上去是HP-UX是吧？）

如果这些解决不了就开case吧，提供详细日志给支持工程师分析一下。

谢谢楼上的几位前辈应该是 偶用syminq -symmids查看到 Type 为Gk的的吧 

偶看到https://community.emc.com/message/398273#398273 老外的帖子。不过说的操作课不敢做。哈

猜测是否由于使用了multi pathed gatekeeper引起的？如果是，解决的方式应该是将gatekeeper 只map到1条路径，至少每条路径3个gatekeeper，然后运行symcfg discover刷新SYMAPI database。

建议客户打800而不要自己操作。
