Add new Equallogic to existing group

At first apologize for my english.
We have purchased the new Equllogic PS-M4110 (Firmware Revision 9.0.2).
We also have 3 Blade: 2xPowerEdge M620, 1xPowerEdge M630 with OracleLinux 6.8 installed.
When a new matrix is ​​added to an existing group, the connections to host volumens are broken.

Configuring MXL 10 / 40GbE switch ports where Equallogic's are located:
Ports 0 / 13,0 / 14,0 / 15,0 / 16,1 / 13,1 / 14,1 / 15,1 / 16 the same configuration

TenGigabitEthernet interface y / xx
 No ip address
 Mtu 12000
 Switchport
 Flowcontrol rx on tx off
 Spanning-tree mstp edge-port
 Spanning-tree rstp edge-port
 Spanning-tree 0 portfast
 Spanning-tree pvst edge-port
 Remote-fault-signaling rx off
 No shutdown
!

Configuring MXL 10 / 40GbE ports where Blade is located
Ports 0 / 1,0 / 2,0 / 3,1 / 1,1 / 2,1 / 3 the same configuration

 No ip address
 Mtu 12000
 Portmode hybrid

 No shutdown

Other switch parameters

No dcb enable

Switch firmware nersion 9.11
 
Host Configuration NICs:

# 10GbE TUNING
Net.ipv4.tcp_sack = 0
Net.ipv4.tcp_timestamps = 0
Net.ipv4.tcp_rmem = 8192 87380 16777216
Net.ipv4.tcp_wmem = 4096 65536 16777216
Net.ipv4.tcp_mem = 10000000 10000000 10000000

Net.core.rmem_max = 16777216
Net.core.wmem_max = 16777216
Net.core.rmem_default = 262144
Net.core.wmem_default = 262144
Net.core.optmem_max = 524287
Net.core.netdev_max_backlog = 300000

Net / ipv4 / conf / bond1 / arp_ignore = 1
Net / ipv4 / conf / bond1 / arp_announce = 2
Net / ipv4 / conf / bond1 / rp_filter = 2
Net / ipv4 / conf / bond1.100 / arp_ignore = 1
Net / ipv4 / conf / bond1.100 / arp_announce = 2
Net / ipv4 / conf / bond1.100 / rp_filter = 2

You may have ideas what is wrong and the session breaks with volumes on the "old" matrix

Thank you very much for your answer.
Yes I'm using bonding on Linux.
It will change the configurations on MPIO and I will work and let you know

Regards

Hello,
Only now has I managed to make changes: changing bonding / bridge to multipath (LInux).
After this change, two Equallogic arrays are OK.
Thank you very much for help

Best regards
