Hello All,
We have a problem here with Disaster Recovery. All hour VMware ESX 3.02 servers see the R1 and the R2 of a SRDF-pair storage the same time.
So we can use DR and Vmotion in the same configuration.
- There is a Disaster on the symmetrix
- On the service console we do a manual failover for the Tier1 LUN with SYMCLI.
- Within ESX Server we change the advanced settings for the ESX server. "LVM.DisallowSnapshotLun from 1 to 0"
- Refresh you datastore
- Your datastore will be visible again with the same datastore name, but it uses now a different SCSI Target ID. (vmhba1:0:70 --> vmhba1:1:70)
- start virtual machines again
Above procedure works fine for EMC Symmetrix DMX 2000..
When we try the same procedure on a EMC Symmetrix DMX 3 system the SCSI Target ID will not change after a failover
Anybody familliar with this problem ? We have to get DR working on the DMX 3 system..
Regards,
Dennis Derks
