Inconsistent behavior with FOS version check for BCZM

[deepali verneya]

When I try attaching 3PAR FC volume to an instance with multiple switch and pre-zoning ,attach volume fails with error “Make sure switch is running firmware v6.4 or higher to caller” occasionally

Step to reproduce:

1. Clear all configurations from switch .(use cfgclear and thn cfgsave)
2. Create zone with one initiator and one target and save the configuration.
3. Configure Brocade zone manager.
4. Create 3PAR FC volume
5. Attach volume to instance

Observation:
Attachment fails with error “Failed adding connection for fabric=None: Error:Failed to get SAN context Unsupported firmware on switch xx.xx.xx.xx . Make sure switch is running firmware v6.4 or higher” .Even though switch FOS version was v7.0.0

Attach your cinder.conf

This is not an issue with invalid firmware, but an issue with MAX logins for user 'admin' has been reached. See log output for CLI request to retrieve version info: Sorry! Max remote sessions for login:admin is 2.

To prevent this, do not open a SSH session outside of OpenStack to the switch. Also, as is recommended, use 'zoneadmin' login, which allows 4 concurrent SSH sessions.

zoning_mode=fabric needs to be in [DEFAULT] section
