Patch Name: PHKL_19058 Patch Description: s700 10.20 VxFS file creation performance improvement patch Creation Date: 99/06/29 Post Date: 99/07/06 Hardware Platforms - OS Releases: s700: 10.20 Products: N/A Filesets: JournalFS.VXFS-BASE-KRN Automatic Reboot?: Yes Status: General Superseded Critical: No Path Name: /hp-ux_patches/s700/10.X/PHKL_19058 Symptoms: PHKL_19058: ( SR: 1653303750 CR: JAGab16358 ) Creating a large number of files (such as > 4k) in a directory on a vxfs file system can take an unacceptably long time to complete, especially when compared to HP-UX 11.00. Defect Description: PHKL_19058: ( SR: 1653303750 CR: JAGab16358 ) On 10.20, VxFS 3.0 uses extents of size 1K blocks once the directory started to use indirect extents; i.e. once the directory became larger. For 11.00 and VxFS 3.1, extents of size 8K are used. Thus, on 10.20, there were 8 times the number of extents to manage as with 11.00. Resolution: A change has been made to allow 10.20 to also use the larger extent size, and thus improve performance.

Back up your system before installing a patch. 2. Login as root. 3. Copy the patch to the /tmp directory. 4. Move to the /tmp directory and unshar the patch: cd /tmp sh PHKL_19058 5a. For a standalone system, run swinstall to install the patch: swinstall -x autoreboot=true -x match_target=true \ -s /tmp/PHKL_19058.depot 5b. For a homogeneous NFS Diskless cluster run swcluster on the server to install the patch on the server and the clients: swcluster -i -b This will invoke swcluster in the interactive mode and force all clients to be shut down. WARNING: All cluster clients must be shut down prior to the patch installation. Installing the patch while the clients are booted is unsupported and can lead to serious problems. The swcluster command will invoke an swinstall session in which you must specify: alternate root path - default is /export/shared_root/OS_700 source depot path - /tmp/PHKL_19058.depot To complete the installation, select the patch by choosing "Actions -> Match What Target Has" and then "Actions -> Install" from the Menubar. 5c. For a heterogeneous NFS Diskless cluster: - run swinstall on the server as in step 5a to install the patch on the cluster server. - run swcluster on the server as in step 5b to install the patch on the cluster clients. By default swinstall will archive the original software in /var/adm/sw/patch/PHKL_19058. If you do not wish to retain a copy of the original software, you can create an empty file named /var/adm/sw/patch/PATCH_NOSAVE. Warning: If this file exists when a patch is installed, the patch cannot be deinstalled. Please be careful when using this feature. It is recommended that you move the PHKL_19058.text file to /var/adm/sw/patch for future reference. To put this patch on a magnetic tape and install from the tape drive, use the command: dd if=/tmp/PHKL_19058.depot of=/dev/rmt/0m bs=2k Special Installation Instructions: This patch depends on base patch PHKL_16750 . For successful installation, please ensure that PHKL_16750 is in the same depot with this patch, or PHKL_16750 is already installed.
