Hello,
I posted a message asking about the following messages :
Bad magic number in disk label!
The file just loaded does not appear to be executable.
I received some responses, but I discoverd that the Sun had a bad fuse !
I just replaced it and everything became fine...
BTW, here are the replies :
1. If the disk is stuck try power up the system while giving the disk a good
smack.
2. Boot up the miniroot to reinstall the boot block :
b sd(0,0,1) vmunix -sw #minirooot
mount /dev/sd0a /a # mount up root partition
cd /usr/mdec
./installboot -vlt /a/boot bootsd /dev/rsd0a
sync
sync
L1-A
The boot block contains the disk label (describes the geometry of the disk)
and the disk partition table (describes where to find the partitions).
3. If it's not a sick device controller or anything else with the disk,
run the format utility to relabel it, seeing before if the format
backup command can find a copy of the old label. Caution : relabelling
a disk from scratch will lose old partitions.
4. If the disk is a large one (more than 2**21 sectors), there is a SCSI
addressing problem. There is a bug in the SunOS SCSI driver : access to
sector (2**21 + N) wraps around to sector N. Solution : boot MUNIX and
miniroot from tape and fix up the partitions tables with format if you
are using too many sectors.
5. If it's a new drive without a installed driver, format the disk using values
supplied by the vendor.
6. Maybe, you forgot to run installboot after regenerating a new root
filesystem or installing a new /boot, or even you ran installboot on the
wrong system.
7. And finally, if anything above can't resolve your problem, maybe you have
to replace the disk !
