It it is set in as split mode.<BR />This is a new box so I want to set up the as mirrored. Mirroring drives 1,3,5,7,9 to 2,4,6,8,10.<BR />I have created 5 vol groups with one drive each. I used sam to do this.<BR />How do I mirror them to the other 5 drives?<BR />Can you help?<BR />Did I miss a step?<BR /><BR />Marty Wed, 29 May 2002 13:23:31 GMT https://community.hpe.com/t5/disk-enclosures/sc10-mirroring/m-p/2733478#M4963 Marty Metras 2002-05-29T13:23:31Z https://community.hpe.com/t5/disk-enclosures/sc10-mirroring/m-p/2733479#M4964 Lets assume that this is what you currently got ..(I'll use the same notation 1,3,5,7,9 and 2,4,6,8,10) since you said you've got 5 VGs created already.<BR /><BR />vg01-disk1<BR />vg02-disk3<BR />vg03-disk5<BR />vg04-disk7<BR />vg05-disk9<BR /><BR />I would prefer to use command line if you don't mind.
