Alcatel Virtual Chassis – neue Firmware als ISSU

Bisher war ein Software Update in einem Virtuellen Chassis immer mit einer Downtime verbunden.

Man musste die Software einspielen und dann beide Member mit der neuen Version booten.

Da die 6900 doch eine gewisse Zeit zum booten brauchen, gab es einen Ausfall im Minuten Bereich.
Mit den neuen Releases (7.3.1.748 und 7.3.2.374R01) wird nun die Möglichkeit eines ISSU (In-Service Software Upgrade) unterstützt.

Vereinfacht spielt man in einen Virtual-Chassis System die Software ein und stößt das Upgrade an.
Dann wird als erstes der Secondary mit der Software versorgt und damit gebootet. Ist er hochgefahren und bereit übernimmt er die Masterrolle und der vorher aktive bekommt die neue Firmware.
Nachdem auch die Box gebootet hat ist das VC mit der neuen Software bereit, der Ausfall sollte dann minimal sein.

Voraussetzung das neue Image (Tos.img und das passende issu_version file) liegt auf dem Master in einem Verzeichnis z.B. new_firm

Konkret:
Kopieren der Konfig

cp working/vcboot.cfg new_firm
cp working/vcsetup.cfg new_firm

Abspeichern (sicher ist sicher)

write memory flash-synchro  

Dann geht es los:

issu from new_firm
