About storage pools and ISP
Veritas Intelligent Storage Provisioning (ISP) allows you to group storage with
similar characteristics for creating volumes. A storage pool is a named collection
of volumes and the LUNs with which they are associated.
The storage policies and rules that are associated with a storage pool determine
its characteristics. Each storage pool represents a collection of volumes that are
created according to these policies and rules. For example, a pool may be configured
to allow allocation of LUNs from outside the pool, and to use only templates that
are associated with the pool by specifying the appropriate autogrow and
selfsufficient policies.
Many rules are supported for storage pools.
See Rules on page 153.
The vxpool utility can create and administer storage pools. For full information
about this command, see the vxpool(1M) manual page.
Reserving and unreserving disks for use with ISP
When you initialize a disk for use with VxVM, for example, by running the
vxdiskadm command, both ISP and non-ISP utilities have access to the space on
the disk. You can reserve a disk for use with either set of utilities by setting the
values of the allocator_reserved and allocator_nouse flags for the disk.
To reserve disks for exclusive use with ISP, and prevent non-ISP utilities from
using these disks, select the following menu item from the main menu of the
vxdiskadm command:
22 Mark a disk as ISP-reserved for a disk group
Alternatively, you can use the following command to reserve a disk specified by
its disk media name for use with ISP:
#vxedit [-g diskgroup] set "allocator_reserved=on" diskname
A disk that is to be reserved for ISP must not contain any existing VxVM subdisks.
To remove the reservation flag from disks, select the following menu item from
the main menu of the vxdiskadm command:
23 Turn off the allocator-reserved flag on a disk
Alternatively, you can use the following command to remove ISP reservation from
a disk specified by its disk media name:
