mapping a volumes to multiple esxi clusters
Hi,
I want to create a iso/template datastore, and I want to map it across multiple clusters.
I get a warning advising against this.....why? What is different from mapping it to one cluster instead of 3? If all the hosts were in one cluster it would make no difference surely?
Cheers

We do the same thing with a lun that holds ISOs and VMware Templates. You are able to map the same Compellent lun to multiple server/cluster objects. The reason it complains about it, is so you are made aware that the lun is already mapped to a different object. Not all server OS's are volume cluster aware and you can/will get data corruption. ESX is volume cluster aware and will not have any issues.
You may have issues adding the same templates to multiple clusters in VMware if your clusters are managed by the same vCenter.

Ah I thought as much, I just found it odd.
Esp since EM is set to know the cluster/hosts are ESXi 5.5, it just adds to the confusion !
