Veritas Volume Manager 5.0.1 Administrator's Guide, HP-UX 11i v3, First Edition, November 2009

■ Place the root disk under VxVM control, and mirror it to create an alternate
boot disk.
■ Designate hot-relocation spare disks in each disk group.
■ Add mirrors to volumes.
■ Configure DRL and FastResync on volumes.
The following tasks are to perform ongoing maintenance:
■ Resize volumes and file systems.
■ Add more disks, create new disk groups, and create new volumes.
■ Create and maintain snapshots.
Unsupported disk arrays
After installation, add any disk arrays that are unsupported by Symantec to the
DISKS (JBOD) category.
See “How to administer the Device Discovery Layer” on page 85.
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.
See “How to administer the Device Discovery Layer” on page 85.
Initialization of disks and creation of disk groups
To place disks in disk groups, use the vxdiskadm program after completing the
installation.
See “Adding a disk to VxVM” on page 107.
Storage pools are only required if you intend using the ISP feature of VxVM.
See the Veritas Storage Foundation Intelligent Storage Provisioning Administrator’s
Guide.
