RHELIIG.book Page 13 Thursday, April 14, 2011 12:15 PM Installing With Dell Unified Server Configuration Dell Unified Server Configuration (USC) provides an OS Deployment wizard that assists you with the installation of Red Hat Enterprise Linux 4 Update 7. NOTE: Dell USC may not provide the latest drivers that are required to complete the installation of the operating system. Download the drivers from the Dell FTP website at ftp.dell.com, or use the Dell Systems Management Tools and Documentation media.
RHELIIG.book Page 14 Thursday, April 14, 2011 12:15 PM NOTE: Upon reboot, the system prompts you to press a key to boot to the operating system media. If you do not press a key, the system boots to the hard drive. It is recommended that you update your system with the drivers extracted in step 4, after the operating system installs. The extracted drivers are located at: /oemdrv. NOTE: All the copied drivers are removed after 18 hours. You must complete the operating system installation within 18 hours.
RHELIIG.book Page 15 Thursday, April 14, 2011 12:15 PM 3 Create a directory on the local hard drive for the Red Hat Enterprise Linux 4 update 9 files. Copy the Red Hat Enterprise Linux 4 update 9 files to this location, or mount the network share containing the Red Hat Enterprise Linux 4 update 9 files. 4 Modify the /etc/sysconfig/rhn/sources file to point to the local directory (or share). 5 Execute up2date -uf to complete the installation procedure.
RHELIIG.book Page 16 Thursday, April 14, 2011 12:15 PM NOTE: You can download the ipmi driver from support.dell.com. Red Hat Enterprise Linux 4 Might Fail to Detect NUMA Nodes On PowerEdge systems that support Non-Uniform Memory Access (NUMA) with the node interleaving disabled in the BIOS, Red Hat Enterprise Linux 4 Update 7 and later may fail to recognize the NUMA nodes and display only node 0.
RHELIIG.book Page 17 Thursday, April 14, 2011 12:15 PM Inconsistent Network Device Enumeration Linux operating system versions that use the udev kernel device manager may enumerate the Network Interface Cards (NICs) differently than earlier Linux versions, that use the devfs device manager. Although this does not affect system functionality when using Red Hat Enterprise Linux 4, NIC1 may be configured as eth1 rather than as eth0, and NIC2 as eth0.
RHELIIG.book Page 18 Thursday, April 14, 2011 12:15 PM 4 Type cat /proc/partitions at the command prompt. The final SCSI device in the list is the USB diskette drive. 5 At the command prompt, type: mkdir -p /mnt/floppy mount /dev/sdx/mnt/floppy where sdx is the SCSI device letter assigned to the diskette drive. Your system can now access the diskette drive.
RHELIIG.book Page 19 Thursday, April 14, 2011 12:15 PM Issues Fixed in Red Hat Enterprise Linux 4 Update 1 Bringing Down an Ethernet Channel Bond May Cause Problems A kernel panic can occur if an Ethernet Channel Bond, which is set up in the 802.3ad Link Aggregation mode, is brought down using the ifdown command. A patch for this issue is available in Red Hat Enterprise Linux 4 Update 1.
RHELIIG.book Page 20 Thursday, April 14, 2011 12:15 PM drivers/usb/input/hid-core.c: input irq status -71 received This issue occurs because the hid-core driver misunderstands a status received from the ehci-hcd driver and prevents the system from shutting down or rebooting. To work around this issue, run the following line before exec $command $HALTARGS in the shutdown script — /etc/rc.d/init.
RHELIIG.book Page 21 Thursday, April 14, 2011 12:15 PM To work around this issue, start the installation with the following command line option: noapic nolapic When both the parameters are passed, the kernel boots and the installation is completed successfully. The parameters are only required when installing the Red Hat Enterprise Linux 4 Update 4 and can be removed once the installation is complete. A fix for this issue is available in Red Hat Enterprise Linux 4 Update 5.
RHELIIG.book Page 22 Thursday, April 14, 2011 12:15 PM A fix for this issue is available in Red Hat Enterprise Linux 4 Update 5. Driver Issue With Integrated 4-Port SATA Controllers On some PowerEdge systems that have integrated 4-port SATA controllers, I/O errors can occur when the system uses drives that support 48-bit logical block addressing (lba48) with drives that do not support lba48. A fix for this issue is available in Red Hat Enterprise Linux 4 Update 5.
RHELIIG.book Page 23 Thursday, April 14, 2011 12:15 PM System Stops Responding Intermittently During Initialization of HPET Timer On certain PowerEdge Systems running the reboot loop service, the system may hang during the High Precision Event Timer (HPET) initialization. The kernel initializes the HPET timer and then performs a verification on the functionality of the timer. This verification may fail and result in a kernel panic. A fix for this issue is available in Red Hat Enterprise Linux 4 Update 7.
RHELIIG.book Page 24 Thursday, April 14, 2011 12:15 PM Number of USB Devices are Restricted to 8 on Certain AMD Processor-Based Systems The ehci-hcd driver in Red Hat Enterprise Linux 4 Update 4 can only handle a limited number of USB devices with interrupt pipes. Only 8 USB devices can be connected to the system at one time. Some USB devices may stop working if more than 8 are attached to the system. A fix for this issue is available in Red Hat Enterprise Linux 4 Update 7.
RHELIIG.book Page 25 Thursday, April 14, 2011 12:15 PM root (hd0,0) kernel /vmlinux-2.6.9-x.EL ro root=LABEL=/ /dev/ht0=ide-scsi initrd /initrd-2.6.9-x.EL.img If your system uses the LILO loader, add the following text to the /etc/lilo.conf file: append="/dev/ht0=ide-scsi" After editing and saving the file, type lilo at the command prompt and press . A fix for this issue is available in Red Hat Enterprise Linux 4 Update 7.
RHELIIG.book Page 26 Thursday, April 14, 2011 12:15 PM NOTE: If the default video driver is set to vesa, then you must not add the NoINT10 line to the Xorg configuration file. Doing so causes the X Window System to fail at startup. A fix for this issue is available in Red Hat Enterprise Linux 4 Update 7. GRUB Installation Fails The grub_install command fails on PowerEdge systems whose BIOS have the No Execute (NX) security feature enabled, which causes the installation to fail with a segmentation fault.
RHELIIG.book Page 27 Thursday, April 14, 2011 12:15 PM To work around the issue, pass the following parameter to the kernel command line at system boot: noexec=off A fix for this issue is available in Red Hat Enterprise Linux 4 Update 7. DRAC 4 Virtual CD Drive Reset May Cause System Instability The use of the default ide-cd driver may cause system lockups when a Dell Remote Access Controller 4 (DRAC 4) reset occurs.
RHELIIG.book Page 28 Thursday, April 14, 2011 12:15 PM Loss of IDE Device Functionality When DRAC 4 is Present Systems with newer Intel chipsets (ICH6, ICH7, and so on) with a DRAC 4 installed may lose functionality of their IDE devices. A workaround for this problem is to pass the following parameter to the kernel command line at system boot: linux ide2=0x1f0 A fix for this issue is available in Red Hat Enterprise Linux 4 Update 7.
RHELIIG.book Page 29 Thursday, April 14, 2011 12:15 PM For systems running these applications, it is necessary to run the systems with NX disabled until the third-party application vendor can supply a version of the application that is compatible with NX. To disable NX, specify noexec= off and noexec32=off on the kernel parameter line in the /boot/grub/grub.conf file. A fix for this issue is available in Red Hat Enterprise Linux 4 Update 7.
RHELIIG.book Page 30 Thursday, April 14, 2011 12:15 PM Red Hat Enterprise Linux 4 Update 7 Snmp Trap Details Not Shown on ITA In Red Hat Enterprise Linux 4 update 7, the implementation of setting various fields of the trap in net-snmp is different. This results in the trap details not being shown when managed from Dell ITA. A fix for this issue is available in the net-snmp package of Red Hat Enterprise Linux 4 Update 8.
