Adding Unsupported Disk Arrays as JBODS
After installation, add any disk arrays that are unsupported by VERITAS to the DISKS
(JBOD) category as described in “Administering the Device Discovery Layer” on page 66.
Adding Foreign Devices
The device discovery feature of VxVM can discover some devices that are controlled by
third-party drivers, such as for EMC PowerPath. For these devices it may be preferable to
use the multipathing capability that is provided by the third-party drivers rather than
using the Dynamic Multipathing (DMP) feature. Provided that a suitable array support
library is available, DMP can co-exist with such drivers. Other foreign devices, for which a
compatible ASL does not exist, can be made available to VERITAS Volume Manager as
simple disks by using the vxddladm addforeign command. This also has the effect of
bypassing DMP. Refer to “Administering the Device Discovery Layer” on page 66 for
more information.
Adding Disks to Disk Groups
To place disks in disk groups, use VEA or the vxdiskadm program after completing the
installation. Refer to “Adding a Disk to VxVM” on page 77 and the VEA online help for
information on how to add your disks to new disk groups.
See the VERITAS Storage Foundation Intelligent Storage Provisioning Administrator’s Guide
for information about creating storage pools within disk groups. Storage pools are only
required if you intend using the ISP feature of VxVM.
