24 Tiered storage solutions
Setting up tiered storage using ISP volumes
If you are creating many volumes at the same time, or you may need to
repeat the procedure in the future, it is preferable to define the volumes to
be created as a volume group in a definitions file, and then use the
vxassist
-M make
command to read this and set up the volumes. For details, see
“Creating multiple volumes” on page 15 and the Veritas Storage Foundation
Intelligent Storage Provisioning Administrator’s Guide.
If you use the predefined templates rather than creating your own, you can
use the
vxassist settag command to add the appropriate tier tag to each
volume as shown in this example:
# vxassist -g mydg settag silvervol tier=silver
6 Use the vxvset command to add the individual volumes to a volume set. For
example, the following command creates a volume set, dst_vset, that
contains the volumes goldvol, silvervol and bronzevol:
# vxvset -g dstdg -t vxfs make dst_vset goldvol
# vxvset -g dstdg addvol dst_vset silvervol
# vxvset -g dstdg addvol dst_vset bronzevol
7 You can now create a Veritas File System (VxFS) on the volume set, and
apply placement policies to the files in that file system. For details, see the
Veritas File System Administrator’s Guide.
