VEA Graphical User Interface and System Management Home Page (SMH)
The Veritas Enterprise Administrator (VEA) provides a Java-based graphical user interface for
managing VxVM. VEA has two parts: a server and a client. The server must run on the system
running VxVM. The client can run on the same machine or on a different machine system to
manage VxVM remotely. Only HP-UX 11i clients are supported. To manage VxVM disks
graphically, you must use the VEA. See “Veritas Enterprise Administrator (VEA 500 Series) Getting
Started Guide? for more information.
System Management Homepage (SMH) replaces System Administration Manager (SAM) on
HP-UX 11i Version 3. SMH has a link to VEA, and you can use this link to invoke VEA from
within SMH. SMH is a web-based administration tool that can be invoked from a remote system
using any of the standard browsers.
Coexistence with HP Logical Volume Manager (LVM)
The Veritas Volume Manager for HP-UX coexists with HP Logical Volume Manager (LVM).
Both LVM and VxVM utilities are aware of the other volume manager, and do not overwrite
disks that are managed by the other volume manager. The administrative utilities (SMH and
VEA) recognize and identify all disks on the system.
A conversion utility, vxvmconvert, is provided for converting non-root LVM volume groups
to VxVM diskgroups.
Limitations of VxVM 4.1 on HP-UX 11i Version 3
The following limitations exist for VxVM 4.1 on HP-UX 11iv3:
• If you migrate from VxVM 5.0 on HP-UX 11i Version 2 to VxVM 4.1 on HP-UX 11i Version3,
VxVM 4.1 will not be able to read the disk group version 140 supported with VxVM 5.0. For
more information on VxVM diskgroups, see “Chapter-4 Creating and Administering Disk
Groups?, “Veritas Volume Manager 4.1 Administrator's Guide? available at http://doc.hp.com.
• VxVM 4.1 does not support the agile view. Only legacy DSFs are supported. VxVM DMP
is in bypass mode on HP-UX 11i Version 3. For information see “Veritas 4.1 Installation Guide?
chapter “VxVM 4.1, New Style DSFs and HP-UX Native Multipathing?, available at http://
docs.hp.com.
