Problem and solution when the BBU is blinking green and orange alternately

6

You can perform the following operations when the BBU is blinking green and orange alternately as follows:
A BBU indicator blinking green indicates that the BBU is being charged, whereas a BBU indicator blinking orange indicates that the BBU is discharging. The possible cause is that the early-version storage system software carries out online tests at low power consumption, and the tests fail. Check event information to see if the insufficient BBU power alarm is reported repeatedly. Check the SES logs for online testing results.
Note:
DisChar indicates the discharging current. 16 indicates that the current value is 1.6 A. If the value ranges from 10 to 20 (1 A to 2 A) and the version of the storage system software is earlier than V100R001C01SPC013 (R1) and V100R002C00SPC004 (R2), the cause of this fault is that the system software carries out online tests frequently due to test failures at low power consumption.
Troubleshooting
Check the version of the system software. If the version is V100R001C00CSPC012 or an earlier version, upgrade it to V100R001C00CSPC013 or a later version.

Problem and solution when a BBU fault alarm is reported and the alarm indicator is red
You can perform the following operations when a BBU fault alarm is reported and the alarm indicator is red: Check the SES log and search keyword invalid OnlineTest (the online BBU test fails). If the keyword exists, verify the BBU type in the SES log. If the product name of BBU is HSCB1-62, the BBUs are BYD BBUs which may cause the problem. Replace BYD BBUs with SCUD BBUs (pay attention to the change during replacement).

Alternative solution to NetScaler in Huawei FusionCloud desktop solution
Citrix NetScaler is no longer supported by Huawei FusionCloud desktop solution. Huawei now provides solutions similar to Citrix NetScaler to provide more flexible access modes. Citrix Netscaler has the following functions: 1) Load balancing: When desktop users log in to the WI page, Netscaler selects an available WI for them to access based on the service load. 2. Access gateway: The IP addresses of user VMs are isolated from those of TCs and SCs, and security encryption is enabled. The new solutions provided by Huawei are as follows: Solution 1: provides software to perform load balancing (vLB) and access gateway (vAG) functions, which completely replaces Citrix Netscaler. This option is easy to deploy and free of charge. If customers require hardware to isolate internal and external networks, they can use universal firewall devices. This is a common solution in the industry. (Currently, VMware uses this solution.) Solution 2: If the customer has purchased Citrix Netscaler (the access gateway only supports the Citrix ICA protocol and does not support other desktop protocols), Netscaler can be used for load balancing alongside Huawei's software access gateway (vAG). Solution 3: provides security a security access gateway from the SVN security product line. Like Citrix Netscaler, it can deliver load balancing and access gateway functions, isolate internal and external networks, and provide SSL encryption capabilities. Solution 1 is recommended because it is simple to deploy and its cost is low.

Problem and solution when a KVM fails
Possible cause: The problem occurs when the power supply is unstable and has transient breaks after the reconstruction of the UPS. Solution: 1. Reinsert the USB cable. 2. If the problem persists, restart the KVM. 3. Replace the faulty keyboard and mouse or the KVM. 4. If the problem persists, restart the SVP.

Problem and solution when the OSPF status is abnormal
To solve the problem that the OSPF status between the firewall and the peer device cannot reach the Full state, perform the following steps: 1. Check the OSPF status. Check whether the OSPF neighboring relationship can be established between the firewall and the peer device. 2. If no, check the security policy configuration. Check whether the security policy control function for unicast packets is enabled. That is, check whether the firewall packet-filter basic-protocol enable command is configured. If yes, run the undo firewall packet-filter basic-protocol enable command to disable the function. To establish an OSPF neighboring relationship, devices need to exchange DD packets. DD packets are OSPF unicast packets. By default, the forwarding of OSPF unicast packets is not controlled by security policies. However, if you run the firewall packet-filter basic-protocol enable command to enable the security policy control function for OSPF unicast packets, you need also to configure the corresponding security policy to allow the packets to be forwarded. For details, see OSPF can not step into full state caused by security policy deny.
