Command Manual – File System Management
Quidway S3900 Series Ethernet Switches-Release 1510
S3900.btm and S3900.web represents host software, Boot ROM files and Web files
respectively.
Note:
You can upgrade files with extensions web, bin and btm.
The file used for upgrading must exist in the root directory of a unit in the fabric.
After the file used for upgrading is synchronized, it will be copied to root directories
of other units in the fabric.
When you execute the update fabric command, the system first collects the free
space information of each unit and then decides whether the available Flash space
is enough on each unit. The available space should be at least 1 K larger than the
size of file used for upgrading. If any space inefficiency is found, the system will
prompt the user to make room on the Flash memory of this unit to complete the
upgrade.
Before the file is copied to all units, the system collects version information of files
with the corresponding type, compares the version compatibility, and outputs the
result. If the file used for upgrading cannot replace the corresponding file on any unit,
the command fails and a message is given, describing the failure reason.
