SUMMARY: SunFire V480, booting problem

Hallo sunmanagers,

I have located the problem. OpenBoot PROM Monitor was not loaded
properly into RAM, therefore some commands as "boot cdrom" and similar
were not giving expected results. The OpenBoot PROM Monitor was not
loaded properly into RAM, as RAM is defected. I got following output
with diag-level set to max:

1>WARNING: DIMM Failure detected in Bank 1

1> DIMM 0 J3100 side 1 = 64MB.

1> DIMM 1 J3101 side 1 = 128MB.

1> DIMM 2 J3201 side 1 = 128MB.

1> DIMM 3 J3200 side 1 = 0MB.


1>WARNING: DIMM Failure detected in Bank 3

1> DIMM 0 J3100 side 2 = 128MB.

1> DIMM 1 J3101 side 2 = 128MB.

1> DIMM 2 J3201 side 2 = 128MB.

1> DIMM 3 J3200 side 2 = 0MB.

Interesting is that only after some time I was able to get the
above results when testing Memory. In the beginning of my
troubleshooting process there was no such error message.

Thank you for all your answers.


With Kind Regards,
Marijan Mumdziev

Subject: SunFire 480, booting problem

Hello SunManagers,

I have a hardware problem with SunFire 480 machine (4 CPUs, and
2GB RAM). For some reason, machine can not boot the OS Solaris anymore.
Error message I'm getting is "Can't locate boot device". Of course, I
have two disks which are mirrored; therefore I have exchanged their
slots. Nevertheless, no result.

1) When I try "boot" command from ok prompt I get following:
ok> boot
Initializing 12MB of memory at addr b0ff000000
Initializing 4080MB of memory at addr b000000000
Initializing 4GB of memory at addr a000000000
Boot device: net File and args:
Can't locate boot device

2) Second approach:
ok> boot disk
Boot device: /pci@9,600000/SUNW,qlc@2/fp@0,0/disk@0,0 File and
args:
Can't locate boot device

3) The same I get for:
ok>boot disk1
ok>boot disk0
ok>boot /pci@9,600000/SUNW,qlc@2/fp@0,0/disk@0,0
...
ok>boot cdrom

4) Additional error message that I get:
Probing /pci@8,600000 Device 1 Corrected ECC Error
{3} ok Corrected ECC Error

In addition to everything, now I have changed a diag-level to
max and it solved a problem partially. Boot command works in general but
disks do not seem to be bootable anymore. I get following errors:

A) Boot device: /pci@9,600000/SUNW,qlc@2/fp@0,0/disk@0,0 File
and args:
The file just loaded does not appear to be executable.

B) mount: I/O error
mount: cannot mount /dev/dsk/c1t0d0s5
/sbin/rcS: /usr/bin/loadkeys: not found
WARNING: /proc could not be mounted
/sbin/swapadd: expr: not found
/sbin/swapadd: swap: not found

WARNING - /usr/sbin/fsck not found. Most likely the
mount of /usr failed or the /usr filesystem is badly
damaged. The system is being halted. Either reinstall
the system or boot with the -b option in an attempt
to recover.

At least "boot cdrom -s" can be executed now. Anyhow, do any of
you guys know what might be the problem here as I need to repair this
machine quickly? Of course, long-term solution is needed. I do not want
to setup the whole system which would appear unstable afterwards.

Thank you very much in advance for your efforts. I will summarize the
solution/conclusion as soon as I have one.

Kind regards,
Marijan Mumdziev
