OpenManage installation does not respond on Red Hat
Enterprise Linux 6
Description Dell EMC OpenManage installation does not respond on PowerEdge R905, 2970, 6950, and T605 systems.
Workaround dcdbas is a native driver in Red Hat Enterprise Linux 6.1. To resolve this issue, download the dcdbas driver at
www.dell.com/support.
Cause This issue is caused due to a defect in the dcdbas driver.
Red Hat Enterprise Linux 6 installation fails with virtual media
Description Red Hat Enterprise Linux 6 installation fails while accessing the iDRAC virtual media.
Workaround
1 Go to www.dell.com/support.
2 Click Drivers & Downloads.
3 Enter your system Service Tag or select your product.
4 From the Operating System drop-down menu, select Red Hat Enterprise Linux 6.
5 From the All PowerEdge XXX les, click Operating System and download the patch.

installation, certain variables may not be available and the installation is forced to terminate.
Known issues in Red Hat Enterprise Linux 6
Kernel panic on PowerEdge R905 systems
Description
Kernel panic may occur on PowerEdge R905 systems when HPET is enabled in the BIOS.
Workaround
This issue does not occur when the HPET setting is disabled (Dell EMC factory default setting).
If the HPET setting is enabled in the BIOS, pass the no_timer_check parameter in the kernel command line.
Cause This issue occurs due to the way the APIC of the system is initialized by the operating system.
Login to iSCSI LUN may fail through multiple interfaces
Description
If there are multiple interfaces on the same subnet and if iSCSI LUN discovery is done using the second interface,
the discovery fails. This issue aects iSCSI iface binding when multiple interfaces are on the same subnet.
Login using the following command succeeds:
#iscsiadm -m discovery -t st -p <IP> -I iface0#iscsiadm -m discovery -t st -p -
I iface0 -l
