Recently we have had two AIX servers give errors indication they could not
find a child device. Today, we had an HBA go bad and replaced it and
rezoned the storage to the new WWN. After cfgmgr was run this error was
received. This also happened on another server that we added storage to and
zoned but we then removed(in our lab). My question; Is there anything in
AIX that "remembers" and when storage is removed or rezoned needs to be
One other common factor is that both servers have EMC storage.
