Netapp E2800 periodically disconnects

[#1]

Possible causes and solution(s)

• Causes

System overview:

• BVMS 11.0
• VRM 4.00
• Netapp 11.70.R2

Also, the behavior explained below was encountered in:

• BVMS: 10.01
• VRM: 3.82.0057
• Netapp: 11.60.2

Netapp DSA E2800 single controllers are disconnecting for a short period of time.

This is sometimes regular once an hour and even in shorter cycles.

The cameras aren’t recording during the disconnection period.

The ping from the VRM and BVMS server runs without problems on management port and iSCSI.

• Solution

✔️ Activate the flow control on the management port from the switch.

• How to configure iSCSI ports of DSA E2800 dual or single controller & configure it in BVMS CC?

According to the NetApp KB, the default management port IP addresses for each controller is shown below:

Default IP addresses for all platforms except EF600 running 11.60 or earlier:

Management Port	Controller A	Controller B	Subnet Mask
1	192.168.128.101	192.168.128.102	255.255.255.0
2	192.168.129.101	192.168.129.102

Note: Default IP addresses are in the form 192.168.XXX.10Y, where:
    XXX = 128 is the first port and 129 is the second port on a controller.
    Y      = 1 is for controller A and 2 is for controller B.

Default IP addresses for all platforms running 11.60.2 and later, or EF600 running 11.60 or later:

Management Port	Controller A	Controller B	Subnet Mask
1	169.254.128.101	169.254.128.102	255.255.0.0
2	169.254.129.101	169.254.129.102

Note: Default IP addresses are in the form 169.254.XXX.10Y, where:
    XXX = 128 is the first port and 129 is the second port on a controller.
    Y      = 1 is for controller A and 2 is for controller B.

🛈 Note

Port 2 on the controllers is reserved for Customer Support use only. It should not be used unless explicitly instructed and the default network settings of DHCP enabled should not be changed.
