How to rebuild vCMP guest VM - Viprion deployment

Hi,

I wonder if anyone had issue vCMP guest VM failure on one slot. I have three slot Viprion with guests set to all slots. After upgrade guest started but the guest VM on slot 2 failed. So now guest is running only on two slots. Slot 2 VM seems to be completely dead:

  • No way to SSH using this slot member IP
  • ssh slot 2 from slot 1 not working
  • vconsole [guest name] 2 from host not working

I was not able to test

tmsh reboot slot 2
from guest slot 1 (Primary) but I highly doubt it will work. Sure I will try reboot guest chassis (like
tmsh reboot slot all
) but what if slot 2 VM will not boot again?

Any proven procedure?

My idea is to:

  • Change guest state to configured
  • Disable guest on slot 2
  • Change state to provisioned - according to info collected:

    • VM will be deleted
    • vdisk will be preserved
  • I think vdisk on slot 2 should be removed - hope can be done via host GUI vCMP ›› Virtual Disk List

After clean up:

  • Change state to configured
  • Enable guest on all slots (original setting)
  • Change state to provisioned, I assume that:

    • VM will be created
    • vdisk will be copied from primary slot
  • Change state to deployed

Should it work? Any better/safer way?

Piotr
