HP Microserver Gen8, ESXi 6.7 here.
I already have DSM 6.1 latest installed in a VM, working just fine. Did not have the guts to migrate it to 6.2 so I decided to first install 6.2 fresh in a new VM. I have been struggling with it for the past 4 days, to no avail, installed kept failing with "corrupt file, error 13" or whatever it was. I even enabled serial via telnet to see what was happening and found out that there was no available partition to install to... or at least this is what it seemed like. So, this is how I made it work:
1. Jun's 1.03b IMG file (with modified grub.conf for serial number and network MAC - this was not even necessary, I could have changed the MAC in VM before starting it, but still...) set up as VMDK running on SATA 0.0, made sure in BIOS that this is the first boot option.
2. A new VMDK created on the SCSI controller (if there is no SCSI disk the DSM installer complains that there is no disk to install to).
3. A third disk, VMDK created on the SATA controller, 0.1. This is used by the DSM installer somehow, I have no idea why and how. Disk at point 2 above is actually used to create md0 and md1 for installing DSM on, for storage pool as well... very odd.
I hope this helps others. Meanwhile I will do some more experiments.
