1 Veritas File System 5.0.1 Release Notes This chapter describes the new features, licensing, system requirements, compatibility with previous releases and known problems with the Veritas File System 5.0.1 on HP-UX 11i v3.
SmartMove provides the following benefits: — — — Less I/O is sent through the host, through the storage network, and to the disks or LUNs. Faster plex creation results in faster array migrations. Ability to migrate from a traditional LUN to a thinly provisioned LUN. This removes unused space in the process. In this release, the SmartMove feature is turned off by default. You can enable this feature by specifying the usefssmartmove=on option in the /etc/default/vxsf file.
NOTE: These features are available only with the HP OnlineJFS license. System Requirements The operating system version supported and the patches required for VxFS 5.0.1 on HP-UX 11i v3 are as follows: • Operating System Version HP-UX 11i v3 0903 OEUR (or later) • Required Patches For information on the required and recommended patches, see Veritas 5.0.1 Installation Guide HP-UX 11i v3. Compatibility With Previous Versions of VxFS The following section discusses the compatibility of VxFS 5.0.
cache size specified in the global (static) tunable, vxfs_bc_bufhwm. If the value of vxfs_bc_bufhwm is set to zero, VxFS automatically tunes the maximum size of the metadata buffer cache at boot time, based on the system memory size. On systems with a RAM size of 1 GB or less, you can manually tune down the value of vxfs_bc_bufhwm to a minimum of 6144 (6 MB). If the user does not manually tune the value of vxfs_bc_bufhwm then VxFS calculates vxfs_bc_bufhwm value based on system memory.
