Requirements

Space requirements per file system vary depending on:

• Whether you select the back out option

• The location of the back out 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

• Whether you are patching a client, a server, or a service area

The install_mu script performs a space analysis for you and reports the space needed per file system, including back out space if applicable. The space calculations take several minutes.

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 back out 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 back out data if desired) and wish to bypass the space calculation, run install_mu with the -f option.

• If you would like to have install_mu report on your disk space availability and need without applying any patches, run install_mu with the -D option.

The MU may only be installed on a system running the Solaris 7 operating environment. In a client/server environment, the MU can only be applied to a client if both the client and server are running the Solaris 7 operating environment.
