[ovirt-users] ovirt hosted-engine on iSCSI offering one target

Hi, We have an oVirt Platforme using the 4.1 version. when the platforme was installed, it was made of : - Two HP Proliant DL380 G9 as hypervisors - One HP MSA1040 for iSCSI - One Synology for NFS - Two switches, one for network/vm traffic, the second for storage traffic. The problem : the hosted-engine domain was created using iSCSI on the HP MSA. The problem is that this disk array does not give the possibility to create different targets, it presents just one target. At that time we create both the hosted-engine and the first data domain using the same target, and we didn't pay attention to the information saying "i*f you are using iSCSI storage, do not use the same iSCSI target for the shared storage domain and data storage domain*". Question : - what problems can be generated by this (mis-)configuration? - Is this a must to do (correct) configuration. Regards.
