does anyone have advice on destroying cluster without CVM access? As you know, JAVA applet doesn’t allow you to reinitialize system because of existing cluster config. And, I don’t have access to CVM or Prism.

1- I have not tried this, but since you have access to the AHV, you should be able to run:
virsh list-all (to get the cvm name and it should show the cvm is not running)
If the cvm does run, try:
visrsh destroy <cvm-name> (this should stop it)
virsh undefine <cvm name>
This should remove the configuration file on that node, You should try this on all nodes
2- If the above does not work, for what you need, run phoenix iso built for your desired AOS, from ipmi and either repair CVM or reinstall CVM (if your intention is to make use of these for another cluster). If that is not your intention, you can use general phoenix iso from your portal and get the disks using the “lssci” command and wipe out the partition tables on each disks using: “dd if=/dev/zero of=/dev/sdX bs=1M count=2048", this destroys the first 2G of the disk and the partition table will gone.
Having said the above, you can actually switch the cvm password to default, using the same phoenix iso as above but mounting the boot drive of the cvm on phoenix shell and modifying the password back to the default value. But this is a very involved process and I suggest you to open a case with support to do so..
Hope this helps a little;
