Hello World:
Recently I ran into an issue where a collegue had installed a Sun T5140 with twin 136GB disks in them. However, he forgot to execute the raidctl command first to mirror c1t0d0 to c1t1d0 boo hoo
So along I come and try to mirror the disks by booting to sigle user mode (boot net -s) from our Jumpstart Server. Once in Single User mode I issued the "raidctl -c c1t0d0 c1t1d0" command and viola, it creates the raid mirror. It also wipes the partition mappings and in the process all data on the boot disk is lost. So of course now I have to halt the system, boot to single user from the net again and re-label the disk again. Finally I can re-jump the system.
My question is as follows:
Is there a way to execute the raidctl command that would create a mirror on the second disk without requiring a re-labeling of the primary disk and without losing all its data?
Respectfully;
Mark K.
