The removal preview phase
These steps occur during the removal preview phase.
- The interim fix manager initializes all commands and libraries, and loads interim fix metadata from the interim fix database.
- The interim fix attributes and descriptions are listed.
- Space requirements are checked. The emgr command checks
whether the target file systems contains adequate space to restore the saved
files. This includes space-changing database entries, restoring saved files,
archiving library members, and other miscellaneous tasks. The emgr command
also adds a small buffer to the various space calculations to account for
file metadata and other factors.
If the user specifies to auto-expand the file system using the -X flag, the emgr command attempts to expand the file system to the required size. If space requirements cannot be met, the emgr command halts the remove operation. If the user specifies a preview installation operation using the -p flag, then the emgr command only reports the space statistics without attempting to expand the file system.
If the user specifies a preview installation using the -p flag, the emgr command does not perform the interim fix removal and skips to the summary and cleanup phase.
