Add mirror chunks using onspaces
About this task
You can use the onspaces utility to
add a primary chunk and its mirror chunk to a dbspace, blobspace,
or sbspace. The following example adds a chunk, chunk2, to
the db_acct dbspace. Because the dbspace is mirrored, a mirror
chunk, mirror_chk2, is also added.
onspaces -a db_acct -p /dev/chunk2 -o 5000 -s 2500 -m /dev/mirror_chk2 5000
