aparrefファイルとprereqファイルを作成。
# cat aparref
none
製品サポートが作成するifixではなく、APARの指定は存在しないためaparrefにはnoneと記述。
# cat prereq
bos.rte.control 7.2.5.201 7.2.5.201
置き換え対象のファイルセット名、下限レベル、上限レベルの順に指定。
ifix形式のファイル作成：
epkgコマンドを使用。
# export LANG=C
# epkg TESTLABEL
Creating efix directory /epkgwork/TESTLABEL.

===============================================================================
Please Note:
All efixes should be marked Live Update capable. This is needed for installing
efixes as a group. If there is a reason an efix is not suitable for a live
update operation, then answer "no" but most efixes should be marked "yes".
===============================================================================
Is this efix suitable for a live update operation ? (yes/no):
-> no <== 一般的にはnoを指定
Enter the location for the APAR reference file.
-> ./aparref <== 事前準備で作成したaparrefを指定
Enter the location for the installp prerequisite file or "." to skip.
-> ./prereq <== 事前準備で作成したprereqを指定、ユーザー作成ファイルの場合は.で問題なし
