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 mfi0 Configuration: 1 arrays, 1 volumes, 0 spares array 0 of 2 drives: drive 0 ( 137G) ONLINE <HITACHI HUS153014VLS300 A410 serial=JFWHSB4C> SAS enclosure 1, slot 0 drive 1 ( 137G) ONLINE <HITACHI HUS153014VLS300 A410 serial=JFWJ3AEC> SAS enclosure 1, slot 1 volume mfid0 (136G) RAID-1 64K OPTIMAL spans: array 0
