The MU7 may only be installed on a system running the Solaris 8, Solaris 8 6/00, Solaris 8 10/00, Solaris 8 1/01, Solaris 8 4/01, Solaris 8 7/01, or Solaris 8 10/01 operating environment.
Space requirements per file system vary depending on:
Whether you select the backout option
The location of the backout directory when saving backout data
The disk partitions and the space available in each file system versus the patch disk space needed per file system
Your system's locale
Whether some of the Maintenance Update patches are already installed on your system
The install_mu script performs a space analysis and reports the space needed per file system, including back out space if applicable. The space calculations take several minutes to complete.
The install_mu script does not proceed if it determines that space is lacking in one or more file systems. Although the patch installation space needed is calculated fairly precisely, the backout data space need is estimated and the reported need may be higher than the actual need.
If you are certain that you have enough space to apply the patch set (and backout data if desired) and you want to bypass the space calculation, run install_mu with the -f option.
