When I boot My Sun Enterprise 250 it is showing the message : Bootdevice : /pci@1f,4000/scsi@3/disk@0,0 WARNING: /pci@1f,4000/scsi@3/sd@0,0 (sd0): Error for command: read Error Level: Retryable Requested Block: 1174977 Error Block: 1174990 Vendor : FUJITSU Serial Number : 9945404767 Sense Key: Media Error ASC:0x11 (), ASCQ:0x1, FRU:0x0 WARNING- fatal error from fsck -error 137 Unable to repair the /filesystem Run fsck manually. How to solve this problem ??? Is it anything to do with devicename DISK and sd currently my HDISK is a scsi why is the system telling me it is a DISK. Is there any configuration to change it from DISK to sd

sd just means scsi disk, in the error messages thats a common abbreviation. I don't know what you mean by disk, do you mean when it boots it displays booting disk..or something of the sort.(this is prior to the OS coming up) if that is what your are talking about then, it is suppose to be that way. "disk" is an alias of the full device path to your hard drive which is located at c0t0d0. you can make up your own name using the nvalias command as long as you include the full device path . at the ok prompt, can you do a probe-scsi. do you even see the disk? ARE you using disksuite...if you are then try to boot to single user and pound out the /dev/md/dsk/c0t0d0s0...then you will need to mount /dev/dsk/c0t0d0s0. If you have a boot server use it to bring this machine into single user mode. I would assume you can do the samething if you are running Veritas. good luck D
