1 Veritas Volume Manager 5.1 SP1 Release Notes This chapter discusses new features, licenses, system requirements, compatibility with previous releases, and known problems with Veritas Volume Manager (VxVM) 5.1 Service Pack 1 (SP1) which is supported on systems running HP-UX 11i v3.
autostartvolume=on. After a disk group split, join, or move operation, VxVM enables and starts the volumes by default. • Cross-platform data sharing support for disks greater than 1 TB In releases prior to VxVM 5.1 SP1, the cdsdisk format was supported only on disks up to 1 TB in size. Therefore, cross-platform disk sharing (CDS) was limited to disks of size up to 1 TB. VxVM 5.1 SP1 removes this restriction. It introduces CDS support for disks of size greater than 1 TB as well.

NOTE: System Administration Manager (SAM) is deprecated in HP-UX 11i v3. HP SMH is the system administration tool for managing HP-UX. HP SMH provides systems management functionality, at-a-glance monitoring of system component health and consolidated log viewing. HP SMH provides Graphical User Interface (GUI), Text User Interface (TUI), and Command Line Interface (CLI) for managing HP-UX. You can access these interfaces using the /usr/sbin/smh command.

vxdg ERROR V-5-1-585 Disk group dgnew: cannot create: Disk for disk group not found This issue can occur if the naming scheme on the slave node where the command was issued is the operating system's native scheme whereas the creation mode uses the new naming scheme. Workaround You can create the shared disk group from the slave node by changing the naming scheme to the operating system's native scheme while in the "Legacy" mode.
Workaround There is no workaround for this issue. Patch will be released in future to fix the issue. • Problem When the system boots for the first time, after installing VxVM 5.1 SP1 or after an upgrade from any older VxVM version to VxVM 5.
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.
Workaround If Virtual I/O (VIO) is used, switch to Accelerated Virtual I/O (AVIO). If problem still persists, use a non-VxVM disk as the boot disk. Patch will be released in future to fix this issue.
