Amdump issues

If you have any problem with amdump first make sure that the command amcheck still succeeds. The amcheck command also points you to a much more detailed and to the point problem area than e.g. the amdump error "all disks failed"

Here is list of issues that amdump may encounter:

Amdump: results missing

Amdump: disk offline

Amdump: dumps way too big, must skip incremental dumps

Amdump: infofile update failed

Amdump: cannot overwrite active tape

Amdump: /sbin/dump returned 1
