Veritas Volume Manager 5.0.1 Release Notes, HP-UX 11i v3, First Edition, November 2009

• Campus Cluster enhancements
The campus cluster feature provides the capability of mirroring volumes across sites, with
hosts connected to storage at all sites through a Fibre Channel network. In this release, the
following enhancements have been made to the campus cluster feature:
— Site Tagging of disks or Enclosures
Enhancements to the vxdisk command related to site tagging are now available:
◦ Site tagging operations on multiple disks or enclosures are now supported.
◦ New option to rename a site tag on a disk or enclosure.
— Automatic Site Tagging
The vxdg settag command now provides an option for automatic tagging of a site.
You can specify that an enclosure is automatically tagged with a particular site name.
When you add a LUN belonging to that enclosure to a disk group, the LUN is tagged
with the specified site name.
— Site Renaming
The vxdg command provides a new renamesite option. The renamesite option
renames the existing site record that is configured on the disk group. The renamesite
option also associates all the volume objects to the new site.
• Estimated Required Time Displayed During Volume Conversion
During a volume conversion operation, before the conversion is committed, the
vxvmconvert command displays the estimated time required as follows:
VxVM INFO V-5-2-4906
The expected time for convert is: 0 hrs 0 mins 7 secs.
• The vxsited daemon Renamed to vxattachd
The vxsited daemon is renamed to the vxattachd daemon. The vxattachd daemon
now also handles automatic reattachment and resynchronization for plexes.
• Automatic Plex Attachment
When a mirror plex encounters irrecoverable errors, VxVM detaches the plex from the
mirrored volume. By default, VxVM automatically reattaches the affected mirror plexes
when the underlying failed disk or LUN becomes visible. When VxVM detects that the
device is online, the VxVM volume components on the involved LUN are automatically
recovered, and the mirrors become usable. The vxattachd daemon handles automatic
reattachment and resynchronization for plexes, and also reattaches sites. After a plex is
successfully reattached, vxattachd notifies the root.
