Storage pools
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.
For more information on the rules that are supported for storage pools, refer to
“Rules” on page 144.
This chapter describes how to use the
vxpool utility to 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 menu item 22 Mark a disk as ISP-reserved
for a disk group from the main menu of the
vxdiskadm command.
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
