Problem booting Sun ultra enterprise 450 server

UNIX Solaris
1

Hi,

I have a sun ultra enterprise 450 server. This server powers on and a white screen appears with the system and network information.

But it doesnot boot up completely. Booting operation wil be halted by a 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.

I am new to this solaris and server world and i dont have any idea what that means.

However i started the boot with -b option and the following appeared:
INIT: Cannot create /var/adm/utmp or /var/adm/utmpx

I thought of reinstalling the OS from the cdrom. I took a solaris 10 sparc OS cd for installation. (is that right?:confused:)

I got an error 'cannot open boot device'

Kindly suggest.

Thanks,
Ashwini

Your E450 server runs a CDROM drive, solaris10 is not CDROM, Solaris10 is copied onto DVD media.

Are you sure you are using right media with the right drive?

did you try the <ok# boot cdrom -s > option ?
then if the system is coming up simply runa fsck for the damaged filesystems
like fsck /dev/dsk/c1t0d0s4 whatever your /usr might be

CD-ROM installations are available for Solaris 10, but IIRC there are 5 CDs.

CD-ROMs are available on solaris 10. You can download the trial version of Solaris 10 onto CD-ROMS but you'll need six of CD-RW 4x 700MB 80min. Try installing Solaris 10.

The E450 server which I have has a DVD drive, and I am using a DVD to boot.

I checked the alias name for the device. Its correct.

Now I am seeing new messages when i give 'boot cdrom' in ok prompt:
Can't open disk label package. Bad magic number in disk label.
along with the error can't open boot device.

I tried 'boot cdrom -s'. same errors.

Please tell me what should i try?
