Subject: 3PAR enable multiattach capability reporting
X-Git-Url: https://review.fuel-infra.org/gitweb?a=commitdiff_plain;h=5f0bd84fc0f6c4db32ec2c73b9ff3a25fbcf35c0;p=openstack-build%2Fcinder-build.git

3PAR enable multiattach capability reporting

This patch enables the reporting of the
multiattach capability in get_volume_stats.
The scheduler currently filters on the capability
for drivers that support/don't support that ability
to do more than one attachment for a volume.
By reporting multiattach = True, it lets the scheduler
know this driver allows attaching a volume more than once.
