Why I did it
Porting changes from DellEMC: S6100 CPLD upgrade #4299 and DellEMC S6100 CPLD upgrade support #3834 to 201911 branch
Added CPLD upgrade support for DellEMC S6100 platform.
Why I did it
serial-getty service exited in Dell S6100 device randomly.
How I did it
Added serial-getty to monit services.
How to verify it
Stop serial-getty in ssh session and check whether the service restarts or not
Why I did it
To handle newer SSD firmware version in DellEMC S6100 platform (S210506G - 3IE devices).
How I did it
Update s6100_ssd_upgrade_status.sh to handle newer SSD firmware version.
How to verify it
Logs: UT_logs.txt
Why I did it
To recover the SSD upgrade state in case, if ONIE-uninstall or ssd_fw_upgrade folder got deleted.
To handle newer SSD version(S21506G - 3IE GPIO7 low devices).
Also correcting the error messages for non-upgraded S6100s.
Why I did it
Added soft-reboot plugin support.
Added SSD version s16425cq check
Added error message to display in console/SSH in case reboot is called in faulty/non-upgraded devices.
Why I did it
To monitor the SSD health condition in DellEMC S6100 platform post upgrade.
A daemon is introduced to monitor the SSD every one hour.
To check for SSD status at boot time and at the time of cold-reboot.
All these changes are supported only for newer SSD firmware.
Added a platform_reboot_pre_check script to prevent cold-reboot based on SSD status.
Depends on Azure/sonic-utilities#1472
DO NOT MERGE UNTIL ABOVE PR IS MERGED
- Why I did it
For fixing PCA MUX attachment issue in Dell S6100 platform.
- How I did it
Wait till IOM MUX powered up properly and start I2C enumeration.
- Xilinx/pericom peripherals are not actively used in DellEMC S6100 switch.
- These peripherals are throwing PCIE corrected messages in some of the units and filling syslog.
- Since it is not usable disabling it at startup.
- optoe driver truncates invalid pages(ff) but sff driver doesn't truncate.so,the DOM related calculation made by sff8436 driver will show incorrect data.
- Few optics doesn't support DOM.
- SFP plugins currently returns None for unreadable pages and this'd throw the below mentioned error in sfpshow eeprom --dom.
Added Reboot Reason for S6000 in platform 2.0
Fixed issue in process-reboot-cause
Added package uninstall code in platform de-init code for z9100, s6100
- How I did it
-> Added support for S6000 Reboot Reason
-> Added platform.py for all platforms
-> Verified show reboot-cause command with the code changes. Added UT logs with show reboot-cause
-> Modified process-reboot-cause service to start after pmon.service. In S6000, we have to wait for nvram to be loaded.
-> If reboot-cause service starts before pmon.service, show reboot-cause is showing incorrect reason.
-> Bug fix in process-reboot-cause file
- import sonic_platform
+ import sonic_platform.platform
The following commit addresses the graceful unmounting of file
system and graceful shutdown of dockers before calling a
cold reboot which will cause a power cycle of SSD. This ensures
orderly shutdown and no corruption of files systems because
of the power cycle to SSD.
This commit will use the existing systemd-reboot service scripts
and override the configuration to do cold reboot for S6100 and
Z9100.
Unit tested the fix and graceful shutdown of file system and
dockers are done with cold reboot.
