再普及一下,VMkernel中自带的多路径算法有三个:Round Robin(循环)、MRU(最近使用)和Fixed(固定),分别针对不同的存储控制器类型,同时vSphere还支持第三方的多路径插件,比如EMC的Powerpath等,但是有可能是收费的。需要在ESXi的shell中通过命令行进行安装。 让我们再回到上边的iSCSI连接的拓扑图,对于独立硬启动器来说,...
In this case, the iSCSI arrays do not return the appropriate SCSI sense code, so a PDL on these array types cannot be detected. Planned versus unplanned PDL A planned PDL occurs when there is an intent to remove a device presented to the ESXi host. The datastore must first be unmounted,...
Determine whether the connectivity issue is with the iSCSI storage or the fiber storage. Perform one of these options depending on what your connectivity issue is. To troubleshoot the connectivity to the iSCSI storage using the software initiator Check whether a ping to the storage array fails fro...
A机的sdb,sdc分别对应OCRVOL1,OCRVOL2,但是B机却反过来了,导致最终B机没有成功。磁盘时通过ISCSI共享过来的,本来想通过指定认盘顺序的方式让两边能够认出序号一样的盘,结果折腾了好久死活两边的盘序都是不一样的。因此,决定换一种方式来做,用UDEV来进行设备绑定,这样应该就不会受到盘序的影响了。 1)用udev来...

If you trigger QLogic 578xx NIC iSCSI connection or disconnection frequently in a short time, the server might fail due to an issue with the qfle3 driver. This is caused by a known defect in the device's firmware. Workaround: None. ESXi might fail during driver unload or controller disco...
As a result, some services such as the vSAN iSCSI Target daemon, which provides vSAN storage with iSCSI protocol, might fail. This issue is resolved in this release. PR 3096769: You see high latency for VM I/O operations in a vSAN cluster with Unmap activated This issue affects vSAN ...

如果IPC 进程的 IPC 数据包中的负载不正确,例如:标头中的版本不正确,则 iSCSI 守护程序中的死锁可能会导致 hostd 服务在 hostd 重新启动后变得无响应。因此,您无法使用 vSphere Client 对受影响的 ESXi 主机和虚拟机执行任何操作。 此版本已解决此问题。 PR 3256705:由于具有父子关系的对象的打开和重命名操作之间...
