Daniel, I finally got time to get back to working on this (work keeps getting in the way) and for the most part, got it working. Still have some testing to do but it installs and works. I did encounter the following problems while trying to get it to work: - The cciss array driver was removed at revision 6499 so I to had to put it back in. - The cciss array driver doesn't always work when compiled as a loadable module. Sometimes the installer will find the logical drives and sometimes it won't. If I compile it into the kernel, it finds the logical drives every time (at least every time I rebooted for testing). After it's installed, appears not to have any problems. - If I use the ILO2 on the HP server and mount the ISO through that, the install hangs. I traced it to the eject program, specifically the "close(fd)" command after the CDROM is actually ejected. I tried a DL360 G5 and DL380 G5 (different ILO firmware versions) and got the same result. Going to try and setup the DL380 G4 I got and see if ILO1 has the same problem. If I manually umount and eject the CDROM from a terminal screen, install gives an error about not being able to eject it but continues without problems.

Subject: RE: [IPCop-devel] IPcop 2.0 on Proliant servers/RAID controllers Daniel, I too would like to see IPCOP able to install on HP servers without a lot of manual work. To help this along, I have setup a Debian system to develop on and begun to make the necessary changes to accomplish this. Unfortunately, because of the way the CCISS driver displays the arrays to Linux (as you pointed out in your message), it will require a number of changes to different parts of the installer to work and not break the current devices it installs to. Currently, I got it to display the Logical Volumes in the drive selection screen. Once I get the selection screen working, will move on to partitioning. I will keep you informed of my progress. Hopefully, if I can get it to work correctly and continue to work for current devices, the changes can be added to the main distribution. Will be testing on a DL380 G4, DL380 G5, and DL360 G5 (the three systems I have available) but expect it would work for any array controller supported by the CCISS driver.

Subject: [IPCop-devel] IPcop 2.0 on Proliant servers/RAID controllers Begging your pardon if this is better on the user mailing list... I've been running IPcop 1.4 on an HP Proliant (PC server) for a while, where it works well (thank you). Upon trying to install 2.0 on the machine, I (and others http://www.ipcops.com/phpbb3/viewtopic.php?f=16&t=16918 ) have found that it does not support the hardware RAID controller in these machines. In more detail, the problem appears to be that the installer does not handle 'unusual' disk device names. My machine (Proliant DL380 G3) contains an integrated "SmartArray 5i", this is handled by the "cciss" driver, which is definitely included in the IPcop 2.0 kernel, however that driver presents the configured RAID disks as block devices (rather than SCSI disks) with names in /dev like /dev/cciss/c0d0 first controller, first disk /dev/cciss/c1d2p1 second controller, third disk, first partition (yes, controller and disk are zero-indexed, partitions are indexed from 1) This is handled fine by the 1.4 installer routine. The following is from my current 1.4 machine: root@milton:~ # ls -l /dev/harddisk* lrwxrwxrwx 1 root root 15 2006-02-09 11:35 /dev/harddisk -> /dev/cciss/c0d0 lrwxrwxrwx 1 root root 17 2006-02-09 11:35 /dev/harddisk1 -> /dev/cciss/c0d0p1 lrwxrwxrwx 1 root root 17 2006-02-09 11:35 /dev/harddisk2 -> /dev/cciss/c0d0p2 lrwxrwxrwx 1 root root 17 2006-02-09 11:35 /dev/harddisk3 -> /dev/cciss/c0d0p3 lrwxrwxrwx 1 root root 17 2006-02-09 11:35 /dev/harddisk4 -> /dev/cciss/c0d0p4 I have tried switching to a VC with a shell while the 2.0 installer is running, and linking /dev/sda to /dev/cciss/c0d0 and /dev/sda1 to /dev/cciss/c0d0p1 etc, then back to the ncurses interface and pressing the "Rescan" button, however that did not make it work. I work for an HP reseller and have access to a number of Proliants, so I can do some testing on various configurations if that helps. Further detail on Linux on the "Proliant" range: Older Compaq-badged proliants (e.g. http://marc.info/?l=ipcop-devel&m=127844232704113&w=2) usually have the cpqarray module, and devices like /dev/ida/c0d0 (I don't think we have any of these for testing - they're bit too old) More recent (generation 3 to 5 or 6) HP-badged proliants have "SmartArray" hardware, driven by the cciss module, and device nodes like /dev/cciss/c0d0 http://cciss.sourceforge.net/ The latest generation of SmartArray hardware is handled by a the 'hpsa' module, which presents the disks as standard SCSI disks, so that they have /dev/sda entries, and should not need any special case handling. - Daniel Challen ________________________________ This email and any files transmitted with it are confidential and intended solely for the use of the individual or entity to whom they are addressed.
