A few of the servers we have monitored throw the following error:
"Some command to the disk failed"

There are three servers which throw this error, two of them have some sort of a HW RAID card, the third one does not.

I have tried upgrading Zabbix server to the newest version (6.4.6 as of today) but it didn't help. The version of the Zabbix Agent2 doesn't seem to play a role either.

• Server #1
  • Supermicro X11SPL-F
  • RAID card: b3:00.0 RAID bus controller: LSI Logic / Symbios Logic MegaRAID SAS-3 3108 [Invader] (rev 02), in IT mode (i.e. the disks are directly visible by the OS)
  • OS: Proxmox 6 (Debian 10)
  • Zabbix-Agent2, versioin 6.2.5
  • Full error message(s):

    SMART [bus/0 megaraid,5]: Some command to the disk failed
    SMART [bus/0 megaraid,4]: Some command to the disk failed
    

• Server #2
  • DELL PowerEdge R240
  • RAID DELL PERC H330 card: 1:00.0 RAID bus controller: Broadcom / LSI MegaRAID SAS-3 3008 [Fury] (rev 02), in IT mode (i.e. the disks are directly visible by the OS)
  • OS: Proxmox 8 (Debian 12)
  • Zabbix-Agent2, versioin 6.4.4
  • Full error message:

    SMART [bus/0 megaraid,1]: Some command to the disk failed
    SMART [bus/0 megaraid,0]: Some command to the disk failed
    

• Server #3
  • Supermicro X11SSM-F-B
  • No RAID card; the disk in question is an external HDD WD My Book 1144 (4 TB)
  • OS: Proxmox 7 (Debian 11)
  • Zabbix-Agent2, versioin 6.4.6
  • Full error message:

    SMART [sde sat]: Some command to the disk failed
    

Server templates for the hosts:

• Proxmox by Zabbix agent active
• SMART by Zabbix agent 2 active - servers - v2
• Systemd by Zabbix agent 2 active
• ZFS on Linux

Agent configuration is pretty barren, just server, hostname, TLS and the default includes.

Let me know if I can provide any more information.

Thank you
