Cisco UCS Hyper-V Cluster – Configure Blade Servers – Part 4

Posted on by

After we have installed the Cisco Blade Servers we now have to do some configuration on the Hosts.

  1. First I activate Remote Management like Remote Desktop, Remote MMC and Powershell.
  2. I add a Firewall rule for Remote Disk Managment 
     netsh advfirewall firewall set rule group="Remote Volume Management" new enable=yes

    Firewall Rule

  3. After adding this firewall rule, I install the Multipath I/O feature 
     ocsetup MultipathIo
  4. Now you can use the MPclaim command-line tool to manage Multipath I/O
    To view all detected enterprise storage:

     Mpclaim -e

    Add MPIO support for Fibre Channel devices:

     mpclaim.exe -r -i -d < _VendorID> < _ProductID>

    Important: Note that the vendor string length is 8 characters, the product string length is 16 characters, and both fields are padded with spaces as needed.

  5. With diskpart you can now see the disks. And you can format the disks with NTFS. Important after that you should take the disks offline to use them in the cluster.
    Diskpart
  6. In the Configuration Menu enable the Cluster Feature.
  7. On each note the all Cluster disks offline. 
    select disk 2
disk offline

In the next post we will configure the Network Adapters of the Cluster notes and create the virtual networks.
