Dying USB stick?

[danswartz]

So I have ESXi 5.0 installed on a lexar usb stick and it's been working fine until now. I happed to be checking the logs on the server (I have a 2.5 SSD for a VM that needs to be on the local datastore), and I see the last couple of days, a lot of messages like:

I ran:

and see:

The 2nd entry here is the lexar usb stick. ESXi seems to think it's dead? Even if it died, my understanding is that the OS is running out of RAM anyway, so this wouldn't have take down the hypervisor. Is this stick history? I guess before anything else, I can try unplugging/replugging it?

Yeah, you are safe to unplug the stick and see if it's dead, everything will keep running as you presumed.

H:0x1 D:0x0 P:0x0 is a permanent device lost scsi sense code.

Thanks, I was hoping that was the case. I'm even more hoping it isn't really dead, but is a transitory USB error - either BIOS related or maybe an esxi driver bug. I'll see when I get home...

Well that sucks. Seems like it will need a reboot. Pulling and replugging that stick (as well as 3 others) doesn't get rid of the vmhba32 turd. Oh well...
