As described in the RAID5.HOWTO, I disconnected one of the SCSI disks.
The raid runs Ok after the rebooting.
My problem is that I can't recover the original full config.
No matter how I change the order of the raidtab, the disconnected-
and-later-reconnected disk is not included in the raid config.
The appended is my raidtab. The reconnected disk is /dev/sdd1.
Do I have to rerun mkraid to use /dev/sdd1 again?
