H06.10 Software Installation and Upgrade Guide

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 Version1 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 H06.10 RVU, in case a fallback becomes necessary. The
DP2 fallback SPR is included on H06.05 and later SUTs.
Fallback
To fall back, you must install the previous SPRs for the OSS products and for DP2. In addition,
in either of these cases, you must run fsck on the fileset to downgrade the fileset to Version 2:
• If the fsck utility has been run on a fileset to upgrade to Version 3 filesets
• If the fileset was created on a system running an H06.08 or later H-series RVU
When the fileset is downgraded to Version 2, any optional ACLs associated with the files in the
fileset are lost.
