Hello, no please don’t use that procedure. You can not post a blank message. Visit my blog about multi-site clustering. When vxio stops receiving requests for reservation status from vxres. If failure is limited to just one disk. This may have meaning to some recalling the event log messages that vxio has lost communication to the cluster and has suspended the reservation thread. I’ll just add that in my experience as someone who troubleshoots disk related issues in clusters for a living, I will say that I find it very rare that you would need to disable cluster disk driver in

Microsoft say to start Win clusters one node at a time, as it is possible cluster disk drivers assume control of disks and set the reserved flag on the disk before sending the reservation. In Windows Cluster Disk driver is a true plug and play. This may have meaning to some recalling the event log messages that vxio has lost communication to the cluster and has suspended the reservation thread.

Hello, no please don’t use that procedure. When vxio suspends the reservation refresh, it means this node is no longer defending the reservation, another node can gain control of the disks and online the service group.
The cluster has failed and another node needs to take over the disks. Vxio will not assume that the cluster has failed, and stop the reservation thread which would result in taking the VMDG offline. Cancel You must be logged in to post a comment.
By suspending the refresh, it will no longer issue the reservation every 3sec, but the reservation will still be present. The cluster has not failed, it is just busy doing something, or the node is busy and hogging resources so the cluster service cannot access the processor.

Hi John, Thanks for your revert, yes it will really help every one of us.
Basicly diswble is the same as r2 but more advanced and better options. There are two possibilities: If not, install the latest applicable version.
How disk resources are reserved in Microsoft Cluster and Failover Cluster
One of the most common issues with Windows Failover clustering deals with the storage attached to the cluster. Tags Failover Cluster Jeff Hughes.
Most common here would be that the signature on the disk that the cluster is looking for has changed. This is documented in the PowerPath installation guide. Upgrade PowerPath to the version needed 6: You must be logged in to post a comment. Office Office Exchange Server.
If you have a lun that is presented to a cluster and you want the data of this disk you can always present this disk to a other machine to access this disk.
This process effectively removes the cluster components diaable the equation.
When vxio stops receiving requests for reservation status from vxres. A few short tests can be performed on the cluster that narrow down where to begin more in depth troubleshooting. Enable cluster disk driver 8: High Availability Clustering https: Diwable the cluster service has brought a basic disk or dynamic disk online, it will issue LooksAlive or IsAlive to the disk resources, these are basically monitor cyclesand used by the cluster to determine the status of the underlying resource.
For basic disks and dynamic disks the LooksAlive process is to in effect send a reservation request every 3 seconds to the resource. Hi, If you have a lun that clusdizk presented to a cluster and you want disabke data of this disk you can always present this disk to a other machine to access this disk.
