Issue number & SR number | Problem summary | Workaround |
---|---|---|
VXFV-296 | Mixing the Mellanox CX-6 100GbE NIC driver with the Broadcom PCIe/OCP 25GbE NIC driver is not supported. | Remove the bnxt_en driver and install the Mellanox driver. |
VXFV-283 | iDRAC support for "Prepare for Removal" on PowerEdge R650/R6525/R750/ nodes fails. | NVMe hot-swap on Linux operating systems is supported. Skip the Prepare for Removal step in iDRAC. |
VXFV-265 | During execution of the command
create-namespace with 4k alignment on RHEL 8.4, the following error is encountered:
Warning: namespace0.0 unable to validate alignment |
This is a false notification. The command result is as expected, and the resulting DAX device can be used with PowerFlex acceleration devices. |
VXFV-243 | Upgrade of a RedHat-based operating system to RHEL 8.3 fails if the node contains NVDIMMs. This is due to a known issue on RHEL 8.3: https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html-single/8.3_release_notes/index#known-issue_installer-and-image-creation | Follow the procedures described in "RHEL/CentOS upgrade to version 8.3" in the Upgrade Dell PowerFlex. |
VXFV-224 | In a RHEL 8.x-based node using Cloudlink encrypted SDS devices, after reboot the device moves to failed state.
NOTE This issue is much rarer on RHEL7.x-based nodes, but it might occur.

VXFV-157 | NVMe disks are not supported on RHEL 8.0 due to the following issue:
https://access.redhat.com/solutions/4280341 Failure to observe this limitation might cause RHEL-based SDSs with NVMes to experience kernel panic during a disk removal flow. |
None |
VXFV-360 | The device name appears incorrectly as Non PCI device instead of iDRAC, but the current and baseline versions are accurate (6.00.30.201 and 6.00.30.202, respectively). | Dell recommends upgrading the OME catalog to the latest version. |
— | PowerFlex nodes running CPLD 1.0.7 stop responding during Power On Self-Test (POST) when upgrading to certain RCM or IC packages that include BIOS 1.8.2 and iDRAC 6.00.30.202. | Before upgrading to the latest supported version of PowerFlex, ensure that the PowerFlex nodes are running CPLD 1.0.8 or later.
