Could anyone please answer why the last command failed?

Sorry, in the problem description instead of ssa1 everywhere should be ssa0.

well I didn't find a manpage for using the ssaraid commnd directly, but first glance is that you are making 3 disks "free" where they should be array candidates if I'm not mistaken.

 

[ogniemi]

free means they are array candidates.

don't ask me why when changing disk to be "array candidate" its status goes in "free"...
