linux - Why does the CentOS 5.8 install give an error about CD-ROM drive when using HP ILO?



CentOS 5.8



I'm trying to install CentOS 5.8 on the following system with the following specs:





  • HP DL360e Gen8

  • HP Dynamic Smart Array 8320i RAID Controller

  • ILO 4 v1.05



I'm connecting the ISO to the server via a virtual disk using HP ILO4.



It initially seems to boot fine... I see lines like: 




Loading vmlinuz........
Loading initrd.img...................


Followed by various bios messages....



Eventually I see the anaconda installer start and get the following message: 



Loading SCSI driver
Loading usb-storage driver...



Followed by:



Loading SCSI driver
Loading ahci driver...


Then finally, I get: 




CD Not Found

CentOS CD was not found in any of your CDROM drives.  Please insert the CentOS CD and press OK to retry.


If I select OK, it gives me the same error.



From what I can dig up, ILO essentially mounts the CD as a USB CD Drive to the system. I'm wondering if for some reason a driver for facilitating this isn't available (although I'm still confused on how I could get this far).



On a side note, I don’t see this specific system (HP DL360e Gen8) listed on the RedHat hardware compatibility list (https://hardware.redhat.com/list.cgi?product=Red+Hat+Hardware+Certification&quicksearch=DL360) There are a lot of DL360s but not this specific model… I wonder if the hardware is different enough to not support it? That being said, I do see RHEL 5.7 listed here: http://h18004.www1.hp.com/products/servers/os/certification.html?var1=DL360e%20Gen8 so perhaps it should work fine?



Answer



You mention that you're using a customized CD image for this. An easy test of the ILO or the driver support for this system is to download a standard CentOS DVD image or possibly a rescue or Live CD. Doing the latter will be quick and an easy way to test if the machine is capable of loading fully. Run the download and see if the system boots. If it does, your issue is the customized CentOS ISO image.



Given that HP is standard hardware with good support for Linux, its drivers are available in most distributions. The SCSI devices should be picked up without incident. The RAID controller uses the HPSA driver on newer OS releases. Yours may end up using the CCISS driver.



You should upgrade the firmware of your ILO as well. The current version is 1.10, and includes a large number of fixes/enhancements. If you have a Windows workstation, you can download the Windows ILO firmware package, extract and update the firmware through the ILO web page.



The same applies to the newest system BIOS.



One more thing. Please make sure you don't have any USB storage connected to the system as you're trying this. That includes USB thumb drives, external hard drives, internal SD cards and anything else in that category.

linux - iDRAC6 Virtual Media native library cannot be loaded

When attempting to mount Virtual Media on a iDRAC6 IP KVM session I get the following error: I'm using Ubuntu 9.04 and: $ javaws -version Java(TM) Web Start 1.6.0_16 $ uname -a Linux aud22419-linux 2.6.28-15-generic #51-Ubuntu SMP Mon Aug 31 13:39:06 UTC 2009 x86_64 GNU/Linux $ firefox -version Mozilla Firefox 3.0.14, Copyright (c) 1998 - 2009 mozilla.org On Windows + IE it (unsurprisingly) works. I've just gotten off the phone with the Dell tech support and I was told it is known to work on Linux + Firefox, albeit Ubuntu is not supported (by Dell, that is). Has anyone out there managed to mount virtual media in the same scenario?

hp proliant - Smart Array P822 with HBA Mode?

We get an HP DL360 G8 with an Smart Array P822 controller. On that controller will come a HP StorageWorks D2700 . Does anybody know, that it is possible to run the Smart Array P822 in HBA mode? I found only information about the P410i, who can run HBA. If this is not supported, what you think about the LSI 9207-8e controller? Will this fit good in that setup? The Hardware we get is used but all original from HP. The StorageWorks has 25 x 900 GB SAS 10K disks. Because the disks are not new I would like to use only 22 for raid6, and the rest for spare (I need to see if the disk count is optimal or not for zfs). It would be nice if I'm not stick to SAS in future. As OS I would like to install debian stretch with zfs 0.71 as file system and software raid. I have see that hp has an page for debian to. I would like to use hba mode because it is recommend, that zfs know at most as possible about the disk, and I'm independent from the raid controller. For us zfs have many benefits,

apache 2.2 - Server Potentially Compromised -- c99madshell

So, low and behold, a legacy site we've been hosting for a client had a version of FCKEditor that allowed someone to upload the dreaded c99madshell exploit onto our web host. I'm not a big security buff -- frankly I'm just a dev currently responsible for S/A duties due to a loss of personnel. Accordingly, I'd love any help you server-faulters could provide in assessing the damage from the exploit. To give you a bit of information: The file was uploaded into a directory within the webroot, "/_img/fck_uploads/File/". The Apache user and group are restricted such that they can't log in and don't have permissions outside of the directory from which we serve sites. All the files had 770 permissions (user rwx, group rwx, other none) -- something I wanted to fix but was told to hold off on as it wasn't "high priority" (hopefully this changes that). So it seems the hackers could've easily executed the script. Now I wasn't able
