Subject: [S390] cio: subchannels in no-path state.
Date: Mon, 18 Sep 2006 16:14:36 +0200 [thread overview]
Message-ID: <20060918141436.GA5612@skybase> (raw)
From: Peter Oberparleiter <peter.oberparleiter@de.ibm.com>
[S390] cio: subchannels in no-path state.
Subchannel may incorrectly remain in state no-path after channel paths
have reappeared. Currently the scan for subchannels which are using a
channel path ends at the first occurrence if a full link address was
provided by the channel subsystem. The scan needs to continue over
all subchannels.
