Veritas Volume Manager 5.0 Release Notes HP-UX 11i v3 (5992-1952, August 2011)

• Default private region size
The default size of the private region has been increased from 1 MB to 32 MB. However, the
default size is still 1 MB for bootable disks, created with vxdisksetup -B.
CAUTION: You must use vxdisksetup -B instead of running vxdisk -B init directly
to initialize bootable disks as the latter command will take up the new default private region
size (32 MB) that does not work for bootable disks.
NOTE: The private region for VxVM bootable disks must start at offset 2144 KB and must
be of size 1 MB.
• Changed behavior of disk group import
In the previous releases, the vxdg import command could not import a disk group if some
disks in the disk group were unusable or inaccessible. The -f option must be specified to
forcibly import the disk group. With this release, a disk group can be imported successfully
if all the disks that were visible when the disk group was last imported successfully, are
accessible. As forcibly importing diskgroups using the -f option counts as a successful import,
the disk group can subsequently be imported without specifying this option.
• Faster startup time
The time required to start the VxVM configuration daemon, vxconfigd, to discover new
devices, to initialize Veritas Storage Dynamic Multi-pathing, and to import disk groups has
been significantly reduced.
• Faster cluster node joins
The time that cluster nodes take to join a cluster has been reduced by allowing concurrent
joins.
NOTE: The fast cluster node join (CVM node join) feature is not available with Base-VxVM
and Full VxVM bundles. To enable this feature, you must install the HP-UX SMS SGeRAC with
CFS License or the CVM (B9117CB) license.
• Support for 16 cluster nodes
The clustering functionality of VxVM now supports up to 16 nodes.
NOTE: The support for 16 node clusters is not available with Base-VxVM and Full VxVM
bundles. To enable this feature, you must install HP-UX Serviceguard Storage Management
Suite.
• SCSI 3 PR enhancement in clusters
The keys for disabled paths are removed so that node joins are not obstructed. In addition,
the time taken to register keys has been reduced.
• File-level SmartSync
The SmartSync feature of VxVM has been extended to support Oracle Resilvering of files on
VxFS file systems. You need to have installed Full-VxVM and OnlineJFS to use this feature.
