Many thanks for the swift and helpful replies, it appears that installing the SCSI card for the external tape has screwed up devaliases, but the system will boot from the internal IDE CDROM if I use the full device path "/pci@1f,0/pci@1,1/ide@3/cdrom@2,0:f". Particular thanks to the following... Peter Stokes:- 1) What SCSI controller do you have? 2) At the ok prompt whet do you get when you issue probe-scsi-all command 3) If you do disconnect all of the SCSI devices does it boot ok to single user (boot cdrom -s)? ................................................... Paul Richards:- This command is attempting to boot from a scsi cdrom, the ultra 5's cdrom is IDE. Is this because you have an external scsi cdrom? If not then you will need to correct the device alias for the cdrom drive. Mine is /pci@1f,0/pci@1,1/ide@3/cdrom@3,0:f you might have to change the cdrom@3 number to match your drive, as I have moved mine to the secondary controller. ........................................................... Joe ( unixadmin ):- Do you have the right path set for the cdrom? what is the output of probe-scsi-all and devalias? make sure that the machine knows the correct path to the cdrom drive. ............................................................ Greg Ulyatt:- The last time I checked, Ultra-5's were IDE, so I'm guessing the SCSI card is a PCI option? If so, then the internal CD is IDE (for sure, unless you installed a scsi one in place of the default) then your boot path may have been changed so as not to scan the IDE bus for boot devices. If you know the device path you could try to boot directly off the CD device (again, assuming it's the internal IDE disk!). You could try: boot /devices/pci@1f,0/pci@1,1/ide@3/sd@2,0:a However, if your cd is scsi&on the bus, it should be ID 6 - the normal boot id for CD's on Sun hardware. ....................................................... Thanks again, ( all I've got to do now is reset the partition table, restore 3 file systems and hope the whole thing will still work !!! There's always a first time for everything ) Laurence This message has been scanned by F-Secure Anti-Virus for Microsoft Exchange as part of the Council's e-mail and internet policy.Received on Tue Nov 27 09:53:20 2001
