# vxedit [-g diskgroup] set "allocator_reserved=off" diskname
To prevent a disk from being used by ISP, enter the following command:
# vxedit [-g diskgroup] set "allocator_nouse=on" diskname
The following command removes the restriction on ISP using a disk:
# vxedit [-g diskgroup] set "allocator_nouse=off" diskname
The flags allocator_reserved and allocator_nouse parameters are mutually
exclusive. Their values cannot both be set to on for a disk.
You can use the vxdisk list and vxprint commands to tell whether a disk has
been reserved for ISP, as shown in the following examples:
# vxdisk list
DEVICE TYPE DISK GROUP STATUS
c0t8d0 auto:cdsdisk mydg1 mydg online allocrsvd
# vxprint -g mydg mydg1
TY NAME ASSOC KSTATE LENGTH PLOFFS STATE TUTIL0 PUTIL0
dm mydg1 c0t8d0 - 35365968 - ALLOC_RES - -
The allocrsvd status flag and the ALLOC_RES state indicate that a disk is reserved
for use with ISP.
Organizing storage pools in a disk group
Before you can use ISP to create volumes in a disk group, you must first create
any storage pools that you require in that disk group. A storage pool has associated
disks, templates and policies. These policies control how the disks and templates
are used when allocating storage from the pool to volumes.
The vxpool organize command simplifies the initial creation of one or more
pools in a disk group by using a storage pool set definition. You can use this
command to create a set of pools with policies and templates that are designed
for a variety of different applications. A storage pool set consists of one data pool
definition and one or more clone pool definitions. Each of these pool definitions
typically consists of the pool type, the templates that the pool contains, and the
pool policies.
For example, if you want your data volumes to be mirrored for redundancy, and
your snapshot volumes to be striped for performance, you can choose a storage
pool set definition where the data pool has associated templates that relate to
