[OpenIndiana-discuss] Unconfigure "hung disk" reports "attachment point not found"

[Jason J. W. Williams]

Hello,

I've got an OpenSolaris 151 server running on a Supermicro X8DTL with
3 LSI 9211-8i controllers in JBOD mode (no SAS expanders). Today one
of the disks in my mirrored zpool hung (100% asvc), which I corrected
by offlining the disk. However, when I go to unconfigure the disk with
cfgadm, it claims "attachment point not found". Any ideas how I can
work around this? Below are the outputs of cfgadm -a and cfgadm -c
unconfigure (the disk in question on is on c15). Thank you in advance.
