Installing ONCplus B.11.31.17 IMPORTANT: Back up your system before installing the product. To install ONCplus B.11.31.17 on your system: 1. Login as root. 2.
Verifying ONCplus B.11.31.17 installation To verify the ONCplus installation: 1. Execute the following command to verify the software installation: swverify ONCplus If ONCplus B.11.31.17 is successfully installed, the following message is displayed: Verification succeeded 2. To check which version of ONCplus is installed on your system, execute the following command: swlist | grep ONCplus The output will be similar to the following: ONCplus B.11.31.17 ONC+ 2.
4. To revert to the previous version of ONCplus enter the following command: swinstall -x allow_downdate=true -x autoreboot=true \ -s /tmp/ONCplus_B.11.31.depot ONCplus NOTE: ONCplus contains kernel filesets. Thus swinstalling the product results in a system reboot after the installation is complete.
WARNING! 1. Problem There is a possibility for an NFS client to experience a system hang if you revert to one of the below ONCplus versions: • ONCplus B.11.31.09 • ONCplus B.11.31.09.01 • ONCplus B.11.31.09.02 Cause The NFS client could hang under below conditions/configurations: • Severe file cache memory pressure due to low file cache configuration. For example, filecache_min = filecache_max =1% • When the nfs3_max_threads tunable is set to “0”.
3. 4. 5. On an HP-UX server with ONCplus B.11.31.07.01 installed, NFSv3 does not fully support large files. Directory related operations on an NFS client with ONCplus B.11.31.06 or B.11.31.07 versions installed along with mounted file systems with read/write permissions that are greater than 8192 bytes in size may result in system panic or data corruption. If your system has ONCplus B.11.31.06 or B.11.31.07 version installed, HP recommends that you install ONCplus B.11.31.07.01 version.
7. ONCplus B.11.31.02 may cause a boot panic situation if you are installing on an HP 9000 rp3410 or rp3440 system with the September 2007 release of HP-UX already installed. If your system has this configuration, Hewlett-Packard recommends that you install the March 2008 release of HP-UX, which includes ONCplus B.11.31.02, or install ONCplus B.11.31.06. You can use the "model" command to print the hardware model information.
8. Problem • The write operation may be interrupted when very large files are copied over NFS. • System crash may occur under heavy load conditions. Solution This problem has been fixed in ONCplus B.11.31.14. Workaround For ONCplus B.11.31.13, the workaround is to use the forcedirectio option for the NFS mount in case of loopback mount or cross mounts with very less UFC cache (say 1%) configured on NFS client systems.
On ONCplus B.11.31.14 version, Fix was implemented only for NFSv3 client version only. To enable this fix on this version, following tunables must be set to the below values: kctune nfs_enable_write_behind = 1 • kctune nfs_enable_ufc_threshold = 1 • kctune nfs3_ufc_threshold_percentage = 50 NOTE: All NFS v3 filesystems have to be unmounted if there is any change in these tunables or UFC filecache_max. Workaround For ONCplus B.11.31.
NOTE: Doing a force unmount may cause data loss for open files. After the unmount is complete, if a program tries to access files from an unmounted filesystem, it will get an EIO error.

3 Features introduced in previous versions of ONCplus This chapter describes the features introduced and defect fixes in all the previous versions of ONCplus B.11.31. • “Features introduced in ONCplus B.11.31.16” (page 26) • “Features introduced in ONCplus B.11.31.15” (page 26) • “Features introduced in ONCplus B.11.31.14” (page 26) • “Features introduced in ONCplus B.11.31.13” (page 27) • “Features introduced in ONCplus B.11.31.12” (page 27) • “Features introduced in ONCplus B.11.31.
Features introduced in ONCplus B.11.31.13 ONCplus B.11.31.13 is a defect fix release and does not include any new features. All features introduced in previous ONCplus versions are supported in ONCplus B.11.31.13. For information on the defects fixed, see “Enhancements and fixes in ONCplus to date” (page 8). Features introduced in ONCplus B.11.31.12 ONCplus B.11.31.12 includes the following enhancement. There are no defect fixes included in this release.
From this version onwards, the minimum configurable value for the following NFS kernel tunables has been increased from “0” to “2” for system stability reasons. • nfs2_max_threads • nfs3_max_threads • nfs4_max_threads NOTE: If the value for any of the above tunables is less than “2”, then the tunable value will be increased to “2” after installation. For information on the defects fixed, see “Enhancements and fixes in ONCplus to date” (page 8). Features introduced in ONCplus B.11.31.09.02 ONCplus B.
New NFS features in ONCplus B.11.31.08 NFS introduces the following features: • The NFS mount structure nfs_args is made public. The NFS structure nfs_args is made public and available for user application development under /usr/include/nfs/mount.h header file. The user applications can make use of this structure to mount NFS shares using mount()system call. For more information on the usage of the structure, see the mount_nfs(1m) manpage. • Asynchronous NFS Direct I/O performance improvement.
New NIS features in ONCplus B.11.31.06 NIS introduces the following feature: • IPv6 support for RPC commands and daemons Phase II ONCplus B.11.31.06 delivers IPv6 support for rpc.rquotad, rpc.rstatd, rpc.sprayd, rup, and spray commands and daemons. New NFS features in ONCplus B.11.31.06 NFS introduces the following feature: • ONC 2.5 functionality for the NFSv2 and NFSv3 client Porting of ONC2.5 Solaris code base to the current HP-UX NFS v2 and NFS v3 client. Features introduced in ONCplus B.11.31.
Features introduced in ONCplus B.11.31.03 ONCplus B.11.31.03 includes both defect fixes and new features. All fixes and features introduced in previous ONCplus versions are supported in ONCplus B.11.31.03. The following features were introduced in ONCplus B.11.31.03: New NFS features in ONCplus B.11.31.03 NFS introduces the following features for NFSv4: • File Delegation with Local Access NFSv4 clients support delegation on HP-UX 11i v3. However, until ONCplus B.11.31.
compliant. This version of CacheFS supports caching for only SYSV_ACLS. Thus, this version of CacheFS on HP-UX supports ACLs with VxFS and NFS and not with HFS. • Support for Logging A new command, cachefslog enables or disables logging for a CacheFS mount-point. If logging functionality is enabled, details about the operations performed on the CacheFS mount-point are stored in a logfile. This logfile contains information on all the CacheFS mount points using the same cache directory.
New NFS features in ONCplus B.11.31_LR • NFS Version 4 Protocol (NFSv4) NFSv4 is an IETF standard protocol that provides the following features: ◦ COMPOUND Procedure In NFSv4, related RPC requests are grouped into a single RPC procedure known as the COMPOUND procedure. The COMPOUND procedure decreases transport and security overhead because of fewer over-the-wire trips between the client and the server. This feature is transparent to the user.
• Secure NFS With Secure NFS security can be implemented at the Remote Procedure Call (RPC) level. This standard authentication system is known as Secure RPC. When NFS uses the facilities provided by Secure RPC, it is known as Secure NFS. RPC authentication enables you to use a variety of authentication systems, such as DH, UNIX, and KERB, and is not dependent on the version of NFS used.
• Backend Support AutoFS supports the storage and distribution of AutoFS maps in the following: • ◦ Files ◦ Network Information Service (NIS) ◦ Lightweight Data Access Protocol (LDAP) Filesystem Support AutoFS supports the automatic mounting and unmounting of the following filesystems: • ◦ NFS (All versions including NFSv4) ◦ CacheFS ◦ HFS ◦ VxFS ◦ CIFS ◦ AutoFS Secure NFS Support If the NFS client supports mounting of secure directories, AutoFS supports Secure NFS filesystems.
• Cache Consistency Checking CacheFS checks the files that are stored in the cache to ensure that the files are kept up to date. With this version of CacheFS, the default behavior is that the consistency checking used can impact CacheFS performance. Following are mount options that can be used to change the type of consistency checking performed by CacheFS: ◦ noconst Disable consistency checking. ◦ demandconst Consistency checking is performed on demand.
• Ipnodes Support Ipnodes is the new map that stores IPv6 information. Ipnodes acts as the new hosts database for IPv6 information. NIS provides support for ipnodes using the /etc/nsswitch.conf file. • Alternate Directory for passwd File Users can now specify a directory other than the default /etc directory where NIS must look for the passwd file. This feature enhances the security of the system, as information regarding this alternate directory is known only to the administrator.
