I have a problem with installation HP-UX 11i V.1 on rp3410

[alymarcor]

I have a server rp3410 with an raid controller 160 and I configured a raid 5 with 3 physical disk. I began an installation of the OS and the procedure is Normal. The system request me the 3 cds and when the system reboot and try to boot of controller first time it show error of SYSTEM CRASH and NO DUMP CONFIGURED. See attachment

I have firmware 44.20 and pdc revision 1

Last I checked RAID 5 required 5 physical disks.

I'm not totally sure and I know you can do Raid 0 on three disks. Thats because I hate raid 5 and totally believe in raid 1.

Why don't you try a less agressive raid configuration and see if the machine comes up after installation.

Do you have "up-to-date" 11i v1 installation media? The rp3410 requires some hardware enablement patches that were not part of the intiila 11i v1 media...

hi,

you can very well configure raid 5 with 3 disks. Infact, RAID5 can be configured with minimum of a three disks.

Interrupt the boot sequence, go into the BCH menu and do a "search" to check the raid volume is getting detected.

If its getting detected, make sure primary path is pointing to the RAID volume. try booting in lvm maintenance mode
hpux -lm and then check whether the lvlnboot information is correct
lvlnboot -v

please revert back with ur observations

with best wishes

Hi Marco,

the cause of the panic is that you could not mount the root filesystem.

=> the Raidcard is recognized by the PDC (bios) of the computer, but not from the HPUX kernel (However, the Install Kernel did recognize the card).
I had a similar problem with HPUX 11.23 and a A9890A raid card. There I had to run the installation in advanced mode and than select manually under software the "RAID-0" software with the ciss driver.
Another possible solution (I never tried this) could be to run the recovery shell from the install medium and copy the installation kernel (automatic recovery procedure) to the root filesystem on the Raid card. I expect that the recovery shell can see the Raid Luns. If not, then try again to install with the RAID-0 software enabled (maybe disabled by default like on HPUX 11.23).

I hope this helps

Stefan

There are a few important things to remember when you are trying to boot from a SmartArray controller with HP-UX.

There are two methods for creating the LUN to which you'll be installing HP-UX:

1. If you are using a PA-RISC system, like the rp3410, you need to use the Ignite recovery shell, and the ciss_insf and sautil commands to create the LUN you want to install to.

2. If you are using an Integrity system, like the rx2600, you will be using the EFI configuration utility called ORCA. The ciss_insf and sautil commands are not included in the Integrity install kernels, because they are not needed.

With both HP-UX 11.11 and 11.23, the RAID-01 software is not Always Installed. You have to select it when you are installing, else you'll run into the issue described here.

After you boot, you can use saconfig and sautil to check your configuration and create more LUNs if you have additional disks available.
