Adding unsupported disk arrays as JBODs

After installation, add any disk arrays that are unsupported by Symantec to the DISKS (JBOD) category as described in “Administering the Device Discovery Layer” on page 85.

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 85 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 97 and the VEA online help for information on how to add your disks to new disk groups.
