I respectfully beg to differ, from Chapter 5, page 33 of Installing, upgrading, or deleting IBM i and related software V7.1:

With the exception of QSYS, QGPL, QUSRSYS, QTEMP, or QSYS2, delete all other libraries from the library list.

I don't remember the exact symptom but I do clearly remember getting bitten by this several years ago, possibly during a V4R5 to V5R1 upgrade, I don't really recall. I called SupportLine and told them what was happening and the first thing they said was "You forgot to take QHLPSYS out of the system library list."

I was sure that there was Knowledgebase Document on this issue but I can't seem to find it now.

I do more IBM i upgrades in a month, than most System administrators
do in their life. I have never seen this in any instructions. Now, if you
want to remove the QHLPSYS LPP option from your machine, you would have to
do that. But a normal upgrade no need.

When you do a Restore of a system, and you have restored your system
values from the SAVSYS tape, it will have QHLPSYS in the System Library list
, but you won't have restored the QHLPSYS library until you do a RSTLIB
*NONSYS (or RSTLIB *IBM), and you might see a message that QHLPSYS isn't

One other thing, I like to remove any libraries above QSYS during an
upgrade, but that is it.

This is more of a curiosity question.

For the last few release updates, the instructions always say to remove
QHLPSYS from QSYSLIBL during the upgrade. What is the reason for this? Is
it so no help is available during upgrades? ;)

If one permanently removes QHLPSYS from the library list, I assume command
help isn't available. OTOH, I have seen posts on this forum that state
QHLPSYS was NOT removed from QSYSLIBL during an upgrade and there were no

So . . .
