I have Sun Fire V440. Boot disks are mirrored. system crashed and it's not coming up. Error message is
Boot disks are mirrored and other disks are ZFS configuration. Please help.
Got an curious issue.
I applied 109147-39 to, oh 15 or so various systems all running Jumpstarted Solaris 8. When I hit the first two V440s, they both failed with Return code 139. All non shell commands segfaulted from then on.
The patch modified mainly the linker libraries and commands.

Hello,
I hope you can help me. I am new to Sun servers and we have a Sun Fire v440 server in which one power supply failed, we are waiting for new one. But now our server is shutting down constantly. Is there any setting with which we can prevent this behaviour? (1 Reply)
Hi all - I have an issue with our (way old) single processor SunFire 280R, running Solaris 9.0.4.
It won't boot even after multiple power cycles. There was a power outage last week end in the computer room, so this might have to do.
In normal boot mode, the screen shows a single line :

First of all it's shut down 60 second after power on and write on console :
SC Alert: Correct SCC not replaced - shutting managed system down!
This is cured by moving out battery from ALOM card.
Now server start to loop during the testing.
That's on the console:

Hello,
I am seeing error messages in V440 (OS = solaris 8). I have copied here :
The system does not reboot constantly and it is up for last 67 days. One more interesting thing I found, I see errors start appearing at 4:52AM last until 6am and again start at 16:52am on same day..

Hi,
I was asked to connect a KVM screen to a Sun Fire V440 last night so I connected it up but no joy and nothing on the KVM screen. I was told that a reboot may fix the problem so connected to the ALOM and rebooted. On the plus side, the KVM screen now works but I lost the ALOM connection.

Hi:
I bougth an used Sun Fire v440, and It have a firmware password. When I turn on the server, it ask for firmware password. (I don 't know what is the correct password). I can access to SC, but when I want to access to OBP, Firmware Password appears again. I remove the battery for two hours,... (1 Reply)
Dear Team,
I need some expert advice to my problem.
We have a Sun Fire v440 in our customer Place. Server is working fine and no hardware deviations are found except one problem that processors generating too much heat. I have verified and found that the room temperature was 26-27 degree.... (5 Replies)
Hi,
I have a SUN Fire V440 server running Solaris 8. One of the 4 disks do not appear when issued the format command. The "ready to remove" LED is not on either.
Metastat command warns that this disk "Needs maintenace". Can I just shutdown and power off the machine and then insert an... (5 Replies)
Hi,
I have a Sun Fire V440 server that fails to boot up correctly. A lot of services are not started and the sytems acts really slow to commands. During boot I can see the following Error:

ccd
CCD(4) BSD Kernel Interfaces Manual CCD(4)NAME
ccd -- Concatenated disk driver
SYNOPSIS
pseudo-device ccd [count]
DESCRIPTION
The ccd driver provides the capability of combining one or more disks/partitions into one virtual disk.
This document assumes that you're familiar with how to generate kernels, how to properly configure disks and pseudo-devices in a kernel con-
figuration file, and how to partition disks.
Note that the 'raw' partitions of the disks must not be combined. Each component partition should be offset at least one cylinder from the
beginning of the component disk. This avoids potential conflicts between the component disk's disklabel and the ccd's disklabel. The kernel
will only allow component partitions of type FS_CCD. But for now, it allows partition of all types since some port lacks support of an on-
disk BSD disklabel. The partition of FS_UNUSED may be rejected because device driver of component disk will refuse it.
In order to compile in support for the ccd, you must add a line similar to the following to your kernel configuration file:
pseudo-device ccd 4 # concatenated disk devices
The count argument is how many ccds memory is allocated for at boot time. In this example, no more than 4 ccds may be configured.
A ccd may be either serially concatenated or interleaved. To serially concatenate the partitions, specify the interleave factor of 0.
If a ccd is interleaved correctly, a ``striping'' effect is achieved, which can increase performance. Since the interleave factor is
expressed in units of DEV_BSIZE, one must account for sector sizes other than DEV_BSIZE in order to calculate the correct interleave. The
kernel will not allow an interleave factor less than the size of the largest component sector divided by DEV_BSIZE.
Note that best performance is achieved if all component disks have the same geometry and size. Optimum striping cannot occur with different
disk types.
Also note that the total size of concatenated disk may vary depending on the interleave factor even if the exact same components are concate-
nated. And an old on-disk disklabel may be read after interleave factor change. As a result, the disklabel may contain wrong partition
geometry and will cause an error when doing I/O near the end of concatenated disk.
There is a run-time utility that is used for configuring ccds. See ccdconfig(8) for more information.
WARNINGS
If just one (or more) of the disks in a non-mirrored ccd fails, the entire file system will be lost.
FILES
/dev/{,r}ccd* ccd device special files.
