H06.11 Software Installation and Upgrade Guide

Guardian applications that use file data and ignore file attributes are unaffected. An application
that performs a 32-bit FILE_OPEN_ of a Format 1 file will successfully open a Format 2 file as
long as the file’s EOF is less than the Format 1 limit of approximately 4 GB.
Guardian applications that use file attributes such as file format and maximum size are likely to
be affected. These programs might fail when unexpected values are returned (such as Format 2
if only Format 1 is expected).
If a Format 2 file does cause a program to fail, the programmer can do one of the following:
• Change the program to accept Format 2 files.
• Protect the program by converting the file to Format 1 using the following commands:
FUP CREATE TEMP, FORMAT-1, TYPE U, CODE 180, &
EXT (28,1400), MAXTENTS 749
FUP COPY MYFILE, TEMP
FUP PURGE MYFILE
FUP RENAME TEMP, MYFILE
• Protect the program by creating a Format 1 file, then appending the desired data to the file.
For example, replace the command:
cp myfile /G/mydisk/mysubvol/myfile
with the commands:
gtacl -c ’FUP CREATE $mydisk.mysubvol.myfile, FORMAT 1, &
TYPE U, ODDUNSTR, CODE 180, EXT (28,1400), MAXTENTS 749’
cat myfile >> /G/mydisk/mysubvol/myfile
OSS Database Files
See the Open System Services Management and Operations Guide and the Open System Services
Installation Guide for information about updating and maintaining OSS database files. See the
Interactive Upgrade Guide 2 for new OSS features and for a summary of migration or installation
issues.
OSS Version 1 Filesets Not Supported
As of the H06.08 RVU, Version 1 filesets are not supported. You must upgrade Version 1 filesets
to Version 2 or Version 3 filesets.
The H06.08 RVU adds support for Access Control Lists (ACLs) for OSS regular files, directories,
first-in/first-out (FIFO) special files, and bound AF_UNIX sockets in OSS Version 3 filesets. To
use OSS ACLs, you must first migrate to the H06.08 or later RVU, then migrate your existing
filesets to Version 3 filesets. To migrate filesets, you must stop the OSS filesystem and the OSS
environment and use the fsck DIAGNOSE FILESET, UPGRADE command as described in the
Open System Services Management and Operations Guide.
To restore backup tapes from H06.08 and later RVUs onto H06.05 through H06.07 RVUs, you
must install the T0744 Backup/Restore 2 SPR. No T0744 Backup/Restore 2 SPR is available for
pre-H06.05 RVUs.
Migration
If you migrate from the H06.04 RVU, HP strongly recommends that you install DP2 fallback SPR
T9053H02^AQM before installing the H06.11 RVU, in case a fallback becomes necessary. The
DP2 fallback SPR is included on H06.05 and later SUTs.
