Mirroring to a Volume Group Question 2

Scott Frye_1 — Wed, 15 Sep 2004 07:38:45 GMT

I have create two volume groups on our SAN. Each VG has one primary and three alternate disks assigned. I want to mirror all my lvols from vg01 to vg02. When I go into SAM and try to do this, it tells me I need 2 PVG's. I never new about PVG's before so I manned vgcreate. I removed my VG01 and recreated it. This time making sure to include the -g paramter so I had "1" PVG.

My second question is, can I mirror lvol1 thru lvol5 all to VG02 so VG02 would look exactly like VG01?

Thanks

Scott,

I assume you're referring to MirrorDisk/UX mirroring which works on a logical volume basis. That is, a logical volume is mirrored to another logical volume within the same VG.
