HP Serviceguard Storage Management Suite Version A.02.00 for HP-UX 11i v3 Release Notes, 3rd Edition, November 2008

— a specified number of volumes with a given intent can be created at the same time
— the vxtemplate listtemplate command can be used to support queries such as:
◦ Given a template, return all template sets that refer to that template
◦ Given a template, list all the templates on which the specified template is dependent
— the linked break-off snapshot volume feature allows the ISP feature to support fast
resynchronization (FastResync) with snapshot operations such as refresh and restore
— migration between non-ISP and ISP volumes
— the ISP intent version number has been increased to 30
• Config Backup and Restore — allows the disk group configuration to be backed up and
restored if configuration information is lost or corrupted
• Multipathing — If HP-UX native multipathing is configured instead of Veritas DMP (Dymanic
Multipathing) with VxVM or CVM disk groups on HP-UX 11i v3, data corruption may occur.
Since DMP is enabled by default for all VxVM and CVM disk groups, no additional
configuration is required to enable DMP, and HP-UX native multipathing will be ignored
by VxVM and CVM disk groups. If patches PHCO_38235, PHKL_38236, PHKL_38241, and
PHKL_38260 are installed, HP-UX native multipathing is supported with VxVM only.
However, VxVM disks configured to use HP-UX native multipathing are not supported on
systems with CVM installed.
NOTE: For more information on VxVM features that are supported with SG SMS version 2.0

What’s New with Veritas Storage Foundation Cluster File System
As of April 2008, for HP Serviceguard Storage Management Suite version 2.0 for HP-UX 11i v3
bundles that include the Veritas™ Storage Foundation Cluster File System (CFS), the following
new CFS features are supported:
• Concurrent I/O support
This feature extends current support for concurrent I/O to cluster file systems. Semantics
for concurrent read/write access on a file in a cluster file system matches those for a local
mount.
• Delaylog supported
The -o delaylog mount option is supported with cluster mounts. This is the default state
for CFS.
• Disk layout version supported
Disk layout Version 7 is now supported on CFS.
