Cumulus Networks has issued this product bulletin to inform you of the following pressing issues affecting one or more Cumulus Networks products and/or versions.
|Release Note ID||Summary||Description||Affected Products & Versions|
|Switch shuts down after suspected bad temperature reading
||An Accton AS4600-54T switch may shut down after a sensor reading incorrectly reports that the temperature is in a CRITICAL state, when it actually isn't.
||Cumulus Linux 2.5.3 and 2.5.3a
|Configuration resets to default after second boot
||This has been after upgrading Cumulus Linux using cl-img-install -u then rebooting in same slot a second time. The overlay gets cleared.
To work around this issue, copy /etc/lsb-release from the read-only slot to /etc/cumulus/init/lsb-release in the read/write slot after the first reboot:
cumulus@switch:~ $ cp /mnt/root-ro/etc/lsb-release /
/mnt/root-rw/config$(fw_printenv -n cl.active)/etc/cumulus/init/lsb-release
|CM-7393: All versions.
CM-6342: Cumulus Linux 2.5.3 and 2.5.3a.
|Dell S4048-ON: Various power off commands render the switch unusable
Issuing a poweroff or shutdown command with certain options shuts down the switch, but it cannot be powered on again. The options that cause this issue are:
- shutdown -h, shutdown -P
- poweroff -n, poweroff -d, poweroff -f, poweroff -i, poweroff -h, poweroff -p
- halt -n, halt -d, halt -f, halt -i, halt -h, halt -p
- init 0
Issuing a reboot command, or using other options, does not trigger this issue.
This issue affects only Dell S4048-ON switches with BIOS version 18.104.22.168 or earlier. To determine the BIOS version of the switch, run:
cumulus@switch:~$ sudo dmidecode -s system-version
This is a known issue, and Dell is issuing a fix soon.
|Cumulus Linux 2.5.3a.
