Release Notes

24. Depending on the virtual storage device attached through iDRAC, that is, USB drive or CD/DVD .ISO file, LC displays Virtual
Floppy or Virtual CD respectively.
25. If the network is not configured and you try to perform a network operation in LC, a warning message is displayed. When you
go to the network settings page from this message, the left navigation panel on network settings page may not be displayed.
26. If a network operation fails for a valid address, try configuring the network settings again. If the issue persists, restart the
system and retry the operation.
27. When you reset or update the iDRAC, you must reboot LC if it is launched already. If you do not reboot, LC may show
unexpected behavior.
28. Fibre-channel NIC cards with dual or four ports are displayed as a single port card in LC. However, all ports are updated
when a firmware update is performed.
29. The option to enable or disable the disk cache policy for SWRAID controllers are supported only on SWRAID controller driver
version 4.1.0-0025 or later.
30. Rollback is not supported for CPLD and HBA controllers.
31. When CMCs are daisy chained, only the first CMC (CMC which is connected to Top of Rack switch) receives LLDP packets.
Other CMCs do not receive LLDP packets. So, the iDRAC network port (dedicated mode) LLDP information is not available
in the blades whose corresponding CMC is not the first CMC in the daisy chain. The LLDP information is also not available
for every CMC in the daisy chain that is not connected to TOR switch directly.
32. If any of the NVMe drives report a 'Failed' status (Red LED) due to any of NVMe controller SMART errors (critical warning
bits set), it should be treated as a predictive failure (Blinking amber LED). These errors include SMART errors such as:
a. Available spare threshold
b. Reliability degraded
c. Read-only mode
d. Virtual memory backup failed, and so on.
33. This note is applicable only to PowerEdge C6420, DCS9650, DCS9670, and DCS9690 systems. If you update iDRAC to this
version from version 3.02.x.x or earlier, you must perform a power cycle of the system before performing any power-related
operations. The power cycle is required to tune the memory parameters without affecting the host. iDRAC tunes the
memory parameters at the first power cycle after a firmware update. To allow the memory tuning to be completed:
a. Update to this version of iDRAC.
b. At the next possible maintenance cycle, or before any power operations are performed, power off the host.
c. Wait for 2 minutes to allow iDRAC to reset and tune the memory parameters.
d. Power on the host.
34. This note is applicable only to PowerEdge M640 and FC640. If you update iDRAC to this version, you must perform a virtual
reseat of the system from CMC. Reseat is required to tune the memory parameters and to resolve issues that may lead to
the watchdog timer causing iDRAC to be reset. To allow the memory tuning to be completed:
a. Update to this version of iDRAC.
b. At the next possible maintenance cycle, perform a virtual reseat.
35. After updating iDRAC Firmware to 3.30.30.30 from a previous version, the first inventory collection after system reboot may
display both PR7 (New Device Detected) and PR8 (Device not detected) messages. This is an expected behavior that is
caused by a change in the slot number display format.
36. Ensure that the SSH client is updated to the latest version. Following SSH configurations are no longer available on iDRAC:
KEX algorithms:
a. diffie-hellman-group14-sha1
MAC:
a. umac-64
b. [e-mail]
37. This note is applicable only to PowerEdge M640 and FC640. When performing BIOS Recovery operation, host may not turn
on. To recover from this condition, do a virtual/physical reseat operation of the blade server.
38. After updating the iDRAC firmware, LC logs may display Message ID PR36 that "Version change detected for PCIe SSD
firmware. Previous version:X.X.X, Current version:X.X.X." This is due to a change in the naming convention. Ignore the log
entry.
39. After downgrading the iDRAC firmware to any previous versions, storage page and drives may display warnings. To resolve
the issue, reset iDRAC using the 'racreset' command.
40. This note is applicable only to PowerEdge R540. While updating the BIOS firmware through local RACADM with local share,
you may get an error "ERROR: RAC989: Unable to apply the BIOS_3P4XY_WN64_1.6.11.EXE firmware update." Use the
direct DUP installation or installation through CIFS/NFS share to update the BIOS firmware.
41. If you get an error while performing SupportAssist collection through RACADM using HTTPS share, use the following
commands to perform the collection:
