Veritas Volume Manager 5.1 SP1 Release Notes HP-UX 11i v3 (5900-1518, August 2011)

NOTE: If a LUN is initialized using the hpdisk format, it cannot be used as a cluster sharable
disk for a CFS cluster.
• Problem
SCSI queries sent on zoned out paths using the scsimgr utility experience a delay of more
than 2 minutes in receiving a response from the SCSI layer. This issue occurs only when the
AD355-60001 HBA and IBM SAN Volume Controller (SANVC) are used in the hardware
configuration.
Workaround
There is no workaround for this issue. Fix will be available in HP-UX 11i v3 September 2011
OEUR.
• Problem
After upgrading from HP-UX 11i v2 VxVM 5.0 to HP-UX 11i v3 VxVM 5.1 SP1, the swverify
Base-VxVM-51 command may display the following warning messages:
WARNING: Directory "/opt/VRTSperl/non-perl-libs" should have mode
"777" but the actual mode is "755".
WARNING: Directory "/opt/VRTSperl/non-perl-libs/bin" should have
mode "777" but the actual mode is "755".
WARNING: Directory "/opt/VRTSperl/non-perl-libs/include" should have
mode "777" but the actual mode is "755".
WARNING: Directory "/opt/VRTSperl/non-perl-libs/lib" should have
mode "777" but the actual mode is "755".
WARNING: Fileset "VRTSperl.VRTSPERL,l=/opt/VRTSperl,r=5.10.0.13"
had file warnings.
Workaround
These messages do not impact the upgrade and can be safely ignored. There is no workaround
for this issue.
• Problem
Starting with VxVM 5.1 SP1 release, VxVM uses the GPT layout for formatting disks of size
greater than 1 TB in cdsdisk format. HP LVM versions lower than HP LVM B.11.31.1104
do not detect VxVM disks formatted with GPT layout. So, when a disk formatted with the GPT
layout is initialized under LVM, it may result in data loss. There will be no warning messages
displayed. This issue occurs on disks of size greater than 1 TB, formatted in cdsdisk format.
Workaround
Upgrade the version of HP LVM on the system to BaseLVM version B.11.31.1104.
• Problem
Starting with VxVM 5.1 SP1 release, VxVM uses the GPT layout for formatting disks of size
greater than 1 TB in cdsdisk format. The diskowner command does not recognize VxVM
disks formatted using GPT layout. This issue occurs on disks of size greater than 1 TB or when
a disk is resized to a size greater than 1 TB.
Workaround
Install the diskowner patch PHCO_41903 on the system to fix the issue.
• Problem
When the system boots after installing VxVM 5.1 SP1, HP VM guests which have VxVM as
root may hang. This happens when there are no worker threads available to process the I/O
errors that occur on the boot disk during the early boot stage.
