The official doc of OpenWrt on VMware HowTo seems already outdated, and there’s no explaination of how to fix
Unsupported or invalid disk type 2 for 'scsi0:0'. Ensure that the disk has been imported. on ESXi 6.7. Here after looked into some clues on Chinese router forums, I found an usable method to convert the image into ESXi VMDK format on macOS.
Download the Image
You can find the
.img.gz files on https://downloads.openwrt.org/, for example:
brew install gzip # To un-gzip .gz files brew install qemu # To convert images
Convert .img to .vmdk
gunzip openwrt-19.07.4-x86-64-combined-ext4.img.gz qemu-img convert -f raw -O vmdk openwrt-19.07.4-x86-64-combined-ext4.img openwrt-19.07.4-x86-64-combined-ext4.vmdk
Upload the VMDK to ESXi
You can either upload the image using
scp command or via web UI. However, I would suggest enable SSH on your ESXi host and use
scp, as the next step requires shell prompt on the host.
scp openwrt-19.07.4-x86-64-combined-ext4.vmdk root@esxi:/vmfs/volumes/datastore1/
Unsupported or invalid disk type 2 for 'scsi0:0'
Before using the
.vmdk file as an “existing hard disk” on ESXi, there’s one more step to convert it into supported disk type.
ssh root@esxi cd /vmfs/volumes/datastore1/ vmkfstools -i 'openwrt-19.07.4-x86-64-combined-ext4.vmdk' openwrt-converted.vmdk -d thin
Done! Now we can create and boot a VM with adding
openwrt-converted.vmdk as the primary disk. Enjoy it!
