Yes, you can substitute a failed drive with a larger capacity, but the RAID configuration will default to the size of the smallest drive in the array. While it's possible to use a slower drive, be aware that this may affect overall performance. [community thread]
This issue is known to occur with HPE ProLiant Gen10/Gen10 Plus servers, where iLO may incorrectly report a critical status due to stale sensor data or misinterpretation of cache states. To resolve this, perform a full power cycle of the server to clear sensor states, or use the iLO CLI to force a hardware health rescan. Additionally, ensure that both iLO and Smart Array controller firmware are updated to the latest versions. [community thread]
The error indicates that the System Programmable Logic Device (PLD) firmware is outdated. To resolve this, ensure the PLD is updated by booting into Intelligent Provisioning and running the firmware update using the Service Pack for ProLiant (SPP). If the PLD does not update, consider contacting HPE support for further assistance. [community thread]
The subpar performance in RAID5 and RAID1 is likely due to the absence of a physical cache module, which is necessary for enabling write-back caching. Without this module, the controller operates in write-through mode, resulting in slower write speeds. To improve performance, ensure a compatible cache module is installed and that the appropriate licenses for caching are applied. [community thread]
NVMe SSDs do not work with hardware RAID controllers, as these controllers are designed for SAS and SATA drives. NVMe drives connect directly to the CPU via PCIe lanes, which means they cannot be configured in RAID using traditional hardware RAID methods. [community thread]
