Ok, been through the forums and tried various suggested issues to the Serial Port install problems for E250's. The Boot CD works properly on my Ultra 5's. However when trying to do an install on my E250 (all via serial console) it always gives me the following and im stuck.


Quote:

* Starting input hotplugging... [ ok ]
* Starting pci hotplugging... [ ok ]
* Starting usb hotplugging... [ ok ]
* Network device eth0 detected, DHCP broadcasting for IP.... [ ok ]
* Auto-scrambling root password for security... [ ok ]
* Starting local... [ ok ]










INIT: Id "s0" respawning too fast: dis



it accepts no more input other than BRK. Anybody have any suggestions?

First thing to check.. In OBP, make sure that both input-device and output-device are set to ttya. You may also try booting with "console=prom".

Thanks for the tip, but no go. Knew about input/output device settings.

Now it just gets to Inittab

Quote:

Started device management daemon v1.3.25 for /dev
* Activating (possible) swap... [ ok ]
* Remounting root filesystem read/write... [ ok ]
* Setting hostname to livecd... [ ok ]
* Mounting local filesystems... [ ok ]
* Mounting USB device filesystem (usbfs)... [ ok ]
* Activating (possibly) more swap... [ ok ]
* Updating inittab... [ ok ]


And now im locked out of console. *sigh* Time for a power reset. and try again =)

Are you running the latest OBP? I have a couple E250s and have not had any issues with them (of course, I installed them back in the 1.4 days, maybe try a 1.4 cd)

May try the 1.4 route if no luck. Been wanting to update OBP but cant get sunsolve access anymore. Sun is mad at me at the moment ;)

Found 3.26 OBP on the web, gonna try and upgrade OBP first.

Will let you know how that goes. Thanks for the responses

GAH! Found the damn problem. Nimrods that set up my serial port only attached the TX/RX pairs. No DTR/DSR.....

I am also setting up an E250 with Gentoo for the first time. I was getting freezing when it was booting the cd but rebooting a couple of times seemed to fix it :?

Let me know how you get on with your build.

How did you manage to set your disks in raid1,
everytime i create the partitions, and then create the filesystem as ext3 my partitions are deleted except on one of the disksive got
/dev/sda booting
/dev/sdb -> /dev/sdf as raid
but from /dev/sdc -> /dev/sdf all partitions are deleted when i build the file system, /dev/sdb is left ok

I pretty much followed Spam's advice from this post


http://forums.gentoo.org/viewtopic.php?t=160585&highlight=raid


Boot Live CD

modprobe md

fdisk your drives accordingly (Use raidautodect partition instead of Linux Native)

Code:

Command (m for help): pr

Disk /dev/sda (Sun disk label): 27 heads, 133 sectors, 4924 cylinders
Units = cylinders of 3591 * 512 bytes

   Device Flag    Start       End    Blocks   Id  System
/dev/sda1             0      4841   8692015+  fd  Linux raid autodetect
/dev/sda2          4841      4924    149026+  fd  Linux raid autodetect
/dev/sda3  u          0      4924   8841042    5  Whole disk




vi /etc/raidtab to as following
Code:

raiddev /dev/md0
        raid-level 1
        nr-raid-disks 2
        persistent-superblock 1
        chunk-size 8
        device /dev/sda1
        raid-disk 0
        device /dev/sdb1
        raid-disk 1

raiddev /dev/md1
        raid-level 1         
        nr-raid-disks 2       
        persistent-superblock 1       
        chunk-size 8       
        device /dev/sda2       
        raid-disk 0       
        device /dev/sdb2       
        raid-disk 1


then "mkraid /dev/md0" & "mkraid /dev/md1"

Then follow Standard Gentoo install, mke2fs -j /dev/md0 stage portage etc etc.

I did copy /etc/raidtab to /etc of md0, not sure if this was a requirement, but did just to cover my backside.

I use initrd anyway, but went ahead and compiled Raid into the kernel instead of modules.

I did a little searching on getting this to boot from the raid as well and now boot from the Raid Partition. I was missing "append="md=0,/dev/sda1,/dev/sdb1""

my /etc/silo.conf looks like this

Code:

partition = 1
append="md=0,/dev/sda1,/dev/sdb1"
root = /dev/md0
timeout = 150
default="gentoo"
message="/boot/boot.msg"

image="/boot/kernel-2.4.28-sparc-r6"
        label="gentoo"
        append="initrd=/boot/initrd-2.4.28-sparc-r6 root=/dev/ram0 real_root=/dev/md0 init=/linuxrc"

image="cat /boot/silo.conf"
label="config"



Hope this helps.


P.S. if you fail and want to remount md0 from LiveCD again. Keep a copy of /etc/raidtab laying around. you will need it to restart the devices again when booting from live CD.

vi /etc/raidtab again and input settings
raidstart /dev/md0
/raidstart /dev/md1

should make devices usable again when booting from LiveCD
