Great thanks to author!
Successfully upgraded 36177xs DSM 6.1.2 in ESXi 6.5 on HP Microserver Gen8 to DSM 6.2.2-24922 in 10 min.
Some key points:
- was not necessary to edit grub.cfg in my case - since 5.x version it works with '"defaults" (MAC/serial as in original loader archive files)
- uploaded vmdk and new 1.03b loader in new folder on storage
- removed all disks from VM
- added new exiting disk SATA0:0 at SATA controller 0 from loader vmdk file at this stage my xpenology booted succesfully (accessible with Synology assistant, but without no hard disk attached)
- added new SATA controller 1 (!) and new disk SATA1:0 from existing DATA vmdk at this stage DSM upgrade process starte successfully: DSM_DS3617xs_23648.pat not installed as old unsupported, but DSM_DS3617xs_24922.pat installed. After upgrade and restart my XPEnology was unacessible over network since I've
- changed network adapter type from old VMNET3 to E1000e.
Thats all, folks.
Now ti works without any problems.
Upgrade to ESXi 6.7 suspended due to performance problems (i've tried it after 6.7 release, even with manual storage driver downgrade but not satisfied)
