Modes

Privileged EXEC mode

tpvm upgrade is an exec CLI.

The new TPVM debian image file is downloaded in the /tftpboot/SWBD2900 directory. If any previous image file was there, it is moved to the /support/OldTpvm directory, if enough space is there.

Note

The snapshot feature may delete this subfolder /support/OldTpvm in order to free space, if required.

During download of the file, if any TPVM is running, it is not disturbed till successful download completion. After that the previously running TPVM (if any) is stopped and uninstalled. If the snapshot parameter is passed in the CLI, then its snapshot is created too. the download may fail due to networking or not enough free space like issues.

If SLX OS configuration database is having TPVM configurations set, specially config deploy, then upgrade process shall further install and start new TPVM debian image file and also apply other TPVM related persisted configurations from the SLX configuration database.
