From 3c0d1d94aa516cad50274fe1aa9f745957b67a65 Mon Sep 17 00:00:00 2001 From: Mike Christie Date: Tue, 28 Jul 2009 23:08:06 -0500 Subject: [SCSI] ALUA: send STPG if explicit and implicit is supported alua_activate only sends a STPG if only explicit is suppored. As a result, for EMC targets that support both we end up doing a implicit failover when X commands are finally sent to the other SP. This patch does a AND on the h->tpgs, so we do a explicit failover right away.
