Thanks to Darren Dunham and John Eisenschmidt for their swift replies. I asked how to implement a triple mirror based backup scheme using Solstice Disk Suite. The basic answer (which worked last night) is: 1) run a script mirror3 which just does metattach d50 d53 (etc.) to attach the 3rd submirror to the existnig mirrors. I run this in the evening. The only reason is performance worries - as we only have 2 HBAs/controllers I prefer to have 2 submirrors during peak hours, 1 on each HBA/controller 2) add to the backup script, after the database servers are shut down but before backup: a) metadetach d50 d53 ie break the 3rd mirrors off b) mount /dev/md/dsk/d50 /lcopy ie remount the broken ex-submirrors on a temporary mountpoint c) restart the live database servers (they're Progress and can't be backed up online) 3) add to the end of the backup script, umount /lcopy ie unmount the temp mount pts. This works. I have not bothered to parse the metastat output yet for (a) resynching in progress (b) bad disks... will try this tonight maybe. -Matt ------------------------------------------------------------------------------------------ This message is confidential.
