concerning the already asked question (Error: (CLI:144) Invalid drive(s) specified when trying to rebuild 3ware RAID) I have an similar issue at my server. My goal is to change the UnitType for all to single (the original state looked like the current state but with one more line for unit 4 similar to unit 5). Therefore I already removed u4 by the command:
tw_cli /c4/u4 remove noscan
Removing /c4/u4 will take the unit offline.
Do you want to continue ? Y|N [N]: Y
Removing /c4/u4 ... Done.
(by the way, migration to single from JBOD is not allowed,
and yes, I guess it was a stupid idea to do so).
Then I tried to add the free disk by:
tw_cli /c4 add type=single disk=3 noscan
The following drive(s) cannot be used [3, 3].
Error: (CLI:144) Invalid drive(s) specified.
I tried several combination of commands but without success. The current state is as follows:
tw_cli /c4 show

p4 OK u5 2.73 TB SATA 4 - ST3000VN007-2E4166
p5 OK u2 1.82 TB SATA 5 - ST2000DM001-1ER164
Any idea how to proceed? And why does the controller add new disks as JBOD by default instead of single?
Many Thanks to help me to rescue my system!
