AIX tar command is not able to uncompress CI0I7ML_OP6.0.1 media package
The AIX default tar command is not able to uncompress the contents of the OP_6.0.1_Non_Embedded_DVD_1.tar.gz, due to "tar" problems related to long file names included.
When uncompressing the .tar file with tar -xvf OP_6.0.1_Non_Embedded_DVD_1.tar.gz the following error occurs:
tar: 0511-169 A directory checksum error on media; -252676160 not equal to 44916.
When using AIX tar the package is not able to uncompress its contents. AIX TAR doesn't uncompress files with long names, and OP_6.0.1_Non_Embedded_DVD_1.tar.gz contains several files with long name patterns.
Resolving The Problem
Use the GNU tar utility (gtar) to extract the files from the downloaded installation package. You can obtain this utility from the IBM AIX Toolbox using the link below, since the AIX tar utility cannot process the archive file.
