    Hello,

    vCenter/ESXi = 7u3

    We have setup an environment with 5 hosts connecting to a SAN (NFS & iSCSI datastores).  DRS is turned on (partially automated).  We have disconnected one of the NICs (etherchannel) during the testing and everything seems to be working.

    What else should I be testing?  Would forcefully powering (cold boot) one of the hosts down be another test?

     

    Thanks,

    TT

    I used to use the iLO/DRAC and power the server off.

    Part of my deployments are always a vSphere HA test of a failing host.

    • Disable DRS
    • Move all VMs away and leave one test VM behind which you can ping
    • If its FT setup place a primary VM on and ping it
    • Configure mail notification for all related vSphere HA alarms
    • Use ILO/iDRAC to shutdown the Host or pull the cable

    Expected behavior

    • Ha should restart the VM within 1min and ping should return
    • FT should protect the VM and there was no interrupt within the ping
    • You will get some Mails

    Because of we are not using HA for VM

    • A long time ago there was a registry key to force a BSOD based an a key command

    They are more tests

    • vMotion
    • svMotion
    • Pulling networking cabled
