Running RHEL 6 on ESXI 6


I am running into problems.... see below... I have a new disk sdc.  I add a single primary partition, then I run luksFormat, seems OK but when I try to run luksUUID it tells me "Device /dev/sdc1 is not a valid LUKS device."

What am I doing wrong?

In my defense I've never seen a linux utility require an uppercase yes.   And in linux "no output" commonly means "success".  How hard would it be a print a message "aborting..." or something like that.

A message would have been nice, yes. You can try showing the return code after the program exist using:

echo $?

Did you manage getting it setup?

To answer if I got this done yet.... The change got put on hold for a couple weeks because we are in a critical production period and can't risk ANY downtime.    But I have followed the same instructions before a few months ago and been just fine... so I think I should be good :-)  Apparently I was being a little more observant the first time around.
