From e9447a46e9fba006ff9b0f4e40a4e38bf2d788db Mon Sep 17 00:00:00 2001 From: "Bryant G. Ly" Date: Tue, 6 Jun 2017 15:45:49 -0500 Subject: [PATCH] ibmvscsis: Use tpgt passed in by user ibmvscsis always returned 0 for the tpg/tag, since it did not parse the value passed in by the user. When functions like ALUA members exports the value, it will be incorrect because targetcli/rtslib starts the tpg numbering at 1. Signed-off-by: Bryant G.
