Why can't add a hot spare?
# mfiutil add e1:s1 mfid0
mfiutil: Drive 1 is not available
I found the reason is e1:s1 is marked online, it must be Marked as an unconfigured good drive, and to mark that it must not be part of an existing array. Then what can i do to get the drive e1:s1 out of array??
# mfiutil show config
