Pinned topic Hyper-V "Cluster"

‏2012-09-26T18:00:54Z |
I have a customer with (3) Hyper-V servers using shared disk. I think the refer to this as High Availability(?)... Just to make sure... I should configure WinRM on all 3 and add them as VMManagers? Or they do have an SCVMM server. Do I install the agent on that instead?

    1. WinRM has to be configured on each Hyper-V host to make ILMT server able to connect and extract required hardware data.

    2. When Hyper-V hosts work in a cluster and credentials used by ILMT server are identical on each of them, then it is enough to configure one connection to VM Manager and mark the option "Share credentials". In such case ILMT server will:
    • connect to the host specified by user as VM Manager
    • get the addresses of all other hosts in the cluster
    • connect to the other hosts using the same credentials and read the required data

    3. By "hosts work in a cluster", I mean that virtual machines are configured as HA services. I think it is possible to configure Hyper-V to run virtual machines from a shared disk (the vm images are shared between multiple Hyper-V hosts), but not configure vms as clustered services.

    Finally got permission from the customer to do the ILMT installs. Now this customer also has the Tivoli Storage Manager (TSM) client installed on the Hyper-V server and backs them up, too. So it's possible to also install the ILMT agent on the Hyper-V host as an "agent" and using your 1-2 steps define them as a VM Manager?

    Hello,

    yes, exactly. In the situation you described it is not only possible but also required. The connections (configured as s.c. "VM Managers") from the ILMT server to Hyper-V hosts provide necessary hardware data that complete the data sent by agents running in virtual machines.
