  • 1.  Monitoring internal SD card (ESXi boot drive).

    Posted Jul 01, 2015 09:26 PM

    Hi All,

    Booting ESXi from SD card is fantastic fetature in ESXi. Although usually everything works great, SD card are not very durable.

    As ESXi can work (by months) with broken SD card as it load into memory unexpected restart can have serious consequences.

    My question is, how to discover such problem. Broken SD card shows in logs. But it would be very confortable to have alarm in vCenter.

    Thanks in advance for any sugestion.

    If your SD card fails you will get an error message in vCenter. If you use a hardware alerting tool eg. HP SIM - you will get an error message in the logs, too.

    What happens when the ESXi boot device (SD card or USB device) fails?

    We had this exact issue onsite last week.  VCenter started reporting "Lost connectivity to the device … backing the boot filesystem. As a result, host configuration changes will not be saved to persistent storage" so we rebooted and it never came back up.  After a lot of phone calls HP replaced the MOBO.

    The host booted into the OS fine on the orginal SD card too so no further config.

    it can be easily monitored by the remote console ,  based of the hardware you use , for example in my case i use CIMC

    and i can check the faulty logs in case my SD had issue .
