@pocopico     The log below is from ttyd. Recently, when booting, I sometimes get a message asking me to reinstall DS3622xs+, probably because it can't find the RAID HDD SHR on the HBA DELL H200. Of course, the assigned IP address can also be changed at will. If you boot again, the RAID HDD is properly detected. What causes these symptoms to recur? please reply.   -------------------------------------------------   SynologyNAS> cat linuxrc.syno.log
