Create or
Modify a Drive
Pool
When an SA, SO, or client uses a Mount Media command and
the specified drive is busy, the command is placed in a
command queue or failed. To increase the likelihood of an
available drive, the Mount Media command may specify a
collection of drives on which to perform the mount. This
collection can be a list of specific drives or a named collection
of drives. Such a named collection is defined as a drive pool and
is created using the Create Drive Pool command.
Features of a drive pool are:
• All defined drives are available for inclusion in a drive pool
• A drive does not need to be associated with an archive to be
a drive pool member
• A drive can be a member of multiple drive pools
• Any mix of drive types can be included in a drive pool as
long as the subject media types are supported by the
VolServ system
• A drive pool may contain zero or more drives
Besides increasing the likelihood of a successful mount, drive
pools can also be used to segregate specific drives to particular
user groups. This can reduce the possibility of drive contention
between such groups.
