Start mirroring for new spaces using onspaces

About this task

You can use the onspaces utility to create a mirrored dbspace. For example, the following command creates the dbspace db_acct with an initial chunk /dev/chunk1 and a mirror chunk /dev/mirror_chk1:

onspaces -c -d db_acct -p /dev/chunk1 -o 0 -s 2500 -m /dev/mirror_chk1 0

Another way to start mirroring is to select Index by Utility > onspaces -m.
