Deploy ESXi on server with more then one disk

Forgot to add messages logs

From the image, it looks like you're using ESXi 7, right? That's not supported at the moment, but we're working on supporting it this cycle.

Yes, you are right we tried to deploy ESXi 7.0.2. Do you know the estimated time to add support of ESXi 7?

Also I found that the entry "multiple devices given. using ‘/dev/sda’ (first available)" comes from the /snap/maas/current/usr/lib/python3/dist-packages/curtin/commands/block_meta.py script.

if len(devices) > 1:
        if args.devices is not None:
            LOG.warn("'%s' mode but multiple devices given. "
                     "using first found", args.mode)
        available = [f for f in devices
                     if block.is_valid_device(f)]
        target = sorted(available)[0]

But I can't understand why there are three devices in the variable "devices"

Declared block devices: ['/dev/sda', '/dev/sdb', '/dev/sda1']

I expected that only device with flag "grub_device: true" should be there.

I tried to deploy Ubuntu to see how much devices maas will find in this case. But I saw that maas didn't use this script during Ubuntu deploying.

Could you please explain me:
1. How and when maas decide to use this script?
2. How it finds devices?
3. And why did you add this check for len(devices) > 1?

For documentation purposes, the fix has been released on MAAS 3.1 and later.
