Invalid UNIX partition

Once the boot program has loaded, it attempts to access the boot disk through the normal UNIX partition information. If this information is damaged, the boot program fails with an error such as:

File just loaded does not appear to be executable

If this message appears during the boot attempt, the system should be booted from an alternate boot disk. While booting, most disk drivers display errors on the console about the invalid UNIX partition information on the failing disk. The messages are similar to this:

WARNING: unable to read label

WARNING: corrupt label_sdo

This indicates that the failure was due to an invalid disk partition. You can attempt to re-add the disk.

See "Re-adding a failed boot disk" on page 50.

However, if the reattach fails, then the disk needs to be replaced.

See "Replacing a failed boot disk" on page 51.
