First of all, let me introduce to you what is Metro1000 V3 device host software. The host software realizes the management, monitoring and control of the operation status of each single board in the network element, and at the same time serves as the communication service unit between the network management system and the single board, realizing the control and management of the network element by the network management system. The function of real-time multitasking operating system of the host software is to be responsible for the management of public resources and to provide support for the application execution program, which isolates the application program from the processor and provides an application execution environment independent of the processor hardware. The communication and control module is the interface module between the host software and the single board software. According to the corresponding communication protocol, realize the communication function between the host software and the single-board software to achieve the purpose of information exchange and equipment maintenance. It sends the maintenance operation commands of the host software to each veneer to each veneer, and on the other hand, reports the corresponding status and alarms of each veneer and performance events to the host software. The device management module is the core part of the host software to realize the device management of the network element, which includes the manager and the agent. The manager can issue network management operation commands and receive events; the agent can respond to the network management operation commands issued by the network manager, and can implement the operation on the managed object, and issue performance events according to the state changes of the managed object. The database management module is an important part of the host software, which includes two independent parts: data and program. The data is organized in the form of database, which is composed of network library, alarm library, performance library and equipment library. The program realizes the management and access to the data in the database.

Problem Description

1. Upgrade the Metro1000V3 device host from 5.37.01.11P02 to 5.37.02.22P02;

2, the upgrade process using the command line ":sys-erase-nesoft:nsf2" erase the second set of nesoft.hwx, prompted erase successfully, for the second set of nesoft.hwx load, prompted "Nesoft has existed! Before download the new one,please erase the old." (as attached)

Alarm message

Load failed with "Nesoft has existed! Before download the new one,please erase the old." (as attached)

Re-delete prompt "failed! cmd:0x0204 error:0x90cb NSERR_SFTM_VERIFY_BACKUPSOFT_FALIED."

Processing

1, due to the prompt host software already exists, then re-use the command line ":sys-erase-nesoft:nsf2" to erase the second set of nesoft.hwx, prompted "failed! cmd:0x0204 error: 0x90cb NSERR_SFTM_VERIFY_BACKUPSOFT_FALIED". 0x90cb NSERR_SFTM_VERIFY_BACKUPSOFT_FALIED."

2, use the command line ":sftm-query-rfile:11, "file://ofs2/hwx/nesoft.hwx";" to query, the original host software can exist again, as follows:

QUERY FILE INFORMATION

BoardId File Type File Name Version File Size

11 NESOFT nesoft.hwx 5.37.01.11P02T04 3597497

Total records :1

3. Use the command line ":sftm-copy-file:11,"/ofs1/hwx/nesoft.hwx", 11,"/ofs2/hwx/nesoft.hwx";" to manually copy the first set of "nesoft.hwx " to the second set manually, then wait 2 to 3 minutes for the copy to complete.

4, re-use the command line ":sys-erase-nesoft:nsf2" to erase, you can erase successfully.

5, erase the successful reload can be.

Root Cause

The host software is not erased completely, resulting in unsuccessful loading.
