Segregating database components
To achieve best performance, it is usual to place the components of a database,
such as the redo log, table spaces and indexes, on different disks. This can be
accomplished by using the disk tagging feature, which allows you to define new
characteristics and then assign these to your disks.
The disk tagging may be accessed by selecting a disk in the Veritas Enterprise
Administrator, and then selecting Actions > Annotate Disks. This feature is also
available from the command line by using the vxdisk settag command. See the
vxdisk(1M) manual page for more information.
Disk tagging can be used in conjunction with volume rules to reserve disks for
particular volumes.
