When I boot My Sun Enterprise 250 it is showing the message :

How to solve this problem ???

Hi,

Looks like your HDD (or the root partition) is having problems... Perhaps a corrupt sector(s).

do STOP+A at this message..

and just type fsck at the ok prompt followed by enter, it should run through everything.

All you can do really is answer yes to the prompts.

I think fsck -Y should run it without asking you all the time, but you really want to see what's wrong.

Additional comment: I had a hard drive crash a while ago and managed to recover pretty much everything, although the fsck /dev/rdsk/c0t3d0s0 that I ran took forever :(

As long as you have a recent backup you really have nothing to fear should things turn out for the worse.

are you mirroring the root disk, if so then you would be able to boot from that disk.

you really shouldn't run fsck -y, using the "-y" option for the most part just deletes info that possibly is needed. especially since it is the root partition. you can run the risk of messing up the os.

if your machine is backed up, which it really should be. It would be a good idea to replace the disk and restore all the data since the integrity of the disk is now in question.

I just found out that
bootdevice : /pci@1f,4000/scsi@3/disk@0,0
but the error message is
/pci@1f,4000/scsi@3/sd@0,0 (sd0):
is it normal or is there any configuration to change from disk to sd since my hdisk are scsi

Have you run fsck manually yet? You have not mentioned what you have tried.

It looks like there is a problem with your root partition, you must run fsck interactively and try to recover it - either that or restore it..

(newfs the partition, mount it on temp mouont point, change to temp mount point, ufsrestore your backup, remove the restoresymtable, unmount, fsck the new filesystem then use installboot to create a boot block, reboot.)

If you don't have a backup I strongly suggest you fsck and recover what you can, then back up what you need & replace the hard drive.

I forgot to mention that I'm using RAID 5

Ah, I'm afraid that's not my field of expertise.... anyone else out there?? :S

Oh, what else may help is if you divulge how your RAID5 is implemented - ie: is it an intelligent hardware device that presents the array as a single disk to the machine, or is it set up in software by something like Disksuite, and therefore a metadevice? This will help in getting more detailed suggestions from people on how to fix the problem.

Obviously if it's a hardware array then all connections, power and so on will have to be checked (which I daresay you'll already have done).

it it presented as a single disk to the machine
