Hi jmjsgi,

for future reference, if you boot an SGI/IRIX machine from CD into miniroot and/or start an install via PROM then it will clobber your boot disk image.

Looking at the file systems only (by putting disk in another machine) you will likely see that it all looks ok, but on restarting it does not find the boot disk.

The reason is that booting into miniroot changes the disk label headings.

To revert back to the original disk label headings you can:

Boot to FX (or run fx from another machine with disk in it) and go into disk "label".

You need to ensure the disk is labeled as boot: "bootfile = /unix"

Here is log example:

Code:

# fx -x
fx version 6.5, Jul 20, 2006
fx: "device-name" = (dksc)
fx: ctlr# = (0)
fx: drive# = (1)
fx: lun# = (0)
...opening dksc(0,1,0)

fx: partitions in use detected on device
fx: devname            seq owner  state
fx: /dev/rdsk/dks0d1s0    1 xfs    already in use

fx: Warning:  this disk appears to have mounted filesystems.
        Don't do anything destructive, unless you are sure that nothing
        you are changing will affect the parts of the disk in use.


...drive selftest...OK
Scsi drive type == ATA    Samsung SSD 840 114P

Also if you have issues with mount points then you need to look at: /etc/fstab and your disk layout.
