Sorry for taking so long to respond,
I'm booting from usb. Trying to do a baremetal upgrade.
DSM 5.0-4493
6 HDD, four of which are in an SHR array.
I was trying to boot from the new Xpenoboot, then upgrade once I got that booted. Is that the way that I should be doing it, or should I be updating DSM, then switching to Xpenoboot?
