Finally! I got my second SATA drive up and running and partitioned and visible to ESXi. I created a 15G datastore on the unused partition of the disk. It’s 15G because I have a 16G USB stick which formats to just over 15G. The cunning plan is to dd the datastore to the USB stick to fool the hypervisor.<\/p>\n

But, first things first. At the moment I have two USB sticks plugged in: the one used to boot ESXi and one newly FAT32 formatted. From ESXi’s busybox I can see the one I boot from, but not the other.<\/p>\n

An extract from fdisk -l<\/code> shows my boot “disk”:<\/p>\n

Partition table entries are not in disk order<\/p>\n

But I should also be able to see mpx.vmhba32.<\/p>\n

This is certainly recognised by ESXi when booting as there are multiple references to it in \/var\/log\/messages<\/code>. There’s a lot of interesting looking usb messages in the log file but the one I see which is causing my current problem I believe is the following:<\/p>\n

So I guess my next mission is to find out how to disable the unclaiming. In the meantime I might use Linux to copy the datastore to the USB stick and see what happens then.<\/p>\n","protected":false},"excerpt":{"rendered":"
