High Availability
Insert additional SPC3 in a multinode high availability (HA) setup (SRX5800, SRX5600, and SRX5400)—Starting in Junos OS Release 22.2R1, you can insert SRX5K-SPC3 cards on the SRX5000 line of devices in a multinode HA setup without interrupting traffic.
You can use the new procedure to insert SPC3 cards when the setup has an encrypted inter-chassis link (ICL) or a non-encrypted ICL.
In case of an encrypted ICL setup, use the new statement
set chassis high-availability hardware-upgrade
on both nodes before you add SPC3 cards.We've also updated the
show chassis high availability information
command output to include messages related to SPC3 installation.[See Multinode High Availability and show chassis high-availability information.]
