1.7 Additional AIX 6 V6.1 Issues:
1.7.1 The Oracle 10gR2 OUI and configuration assistant programs do not recognize AIX 6 V6.1 as a supported release:
1.7.1.1 Resolution:
For the OUI program, use the ‘-ignoreSysPrereqs’ option as in the command: ‘ ./runInstaller –ignoreSysPrereqs’
For the configuration assistant program, select the skip validation option and continue to verify other errors.
1.7.2 The Oracle 10gR2 “rootpre.sh” program displays unnecessary error messages related to AIX AIO.
1.7.2.2 Problem description:
When running the ‘rootpre.sh’ program, messages like the following will be displayed:
Configuring Asynchronous I/O....
Asynchronous I/O is not installed on this system.
You will need to install it, and either configure it yourself using
'smit aio' or rerun the Oracle root installation procedure.
Configuring POSIX Asynchronous I/O....
Posix Asynchronous I/O is not installed on this system.
You will need to install it, and either configure it yourself using
'smit aio' or rerun the Oracle root installation procedure.
1.7.2.3 Resolution:
§ Ignore Errors:
The error message is generated because “rootpre.sh” is enabling the POSIX AIO and Legacy AIO devices for Oracle use. In AIX 6 V6.1, AIO (Asynchronous I/O) is installed and enabled automatically and the individual AIX Asynchronous I/O devices like ‘aio0’ and ‘posix_aio0’ no longer exist.
Therefore this is not a problem. However, users should verify that no other script failures have occurred.
§ Download new ‘rootpre.sh’ from Oracle MetaLink:
A replacement ‘rootpre.sh’ is available for download from Oracle MetaLink. Reference Oracle bug# 6613550 or ARU# 9638501.
1.7.3 Note: AIX 6.1 will issue an error message when attempting to create a volume group with a disk that is formatted by Oracle ASM.
1.7.3.4 Details:
This additional checking by AIX was to prevent accidentally overwriting an Oracle ASM disk.
The error message from the ‘mkvg’ command will be similar to the following:
0516-1339 /usr/sbin/mkvg: Physical volume contains some 3rd party volume group.
0516-1397 /usr/sbin/mkvg: The physical volume hdisk1, will not be added to
the volume group.
0516-862 /usr/sbin/mkvg: Unable to create volume group.
The force option (-f) on the ‘mkvg’ command will not work for an ASM disk. The AIX ‘dd’ command can be used to clear the Oracle ASM information for the disk. The following is a sample command:
dd if=/dev/zero/ of=/dev/rhdisk1 bs=1024 count=10
