1. Make sure that the hard disk drive partitions listed match the partitions for your system configuration You can determine the appropriate partitions by examining your Volume ID chart prepared when your system was installed or by reading the applicable information in your n STAR System Administrator s Guide For example if you have a Supermicro 32 with a 60M byte drive having 8 parti tions your screen should look like this A gt TYPE TAPEDISK DAT RETURN BCDEFGJK A Remember that when you run your computer in Diagnostic Mode the A partition of the hard disk becomes the B partition because the diskette becomes the A drive This means that Volumes which reside on the A partition of your hard disk in Multiuser Mode will be located on the B partition while you are 052484 RN9 28 v operating in Diagnostio Mode This is important keep it in mind when you are using the LTAPE program To backup or restore the Multiuser A partition you must specify the B partition In our example above the partitions under Multiuser Mode have the following correspondence Diagnostic Mode Partitions Oc tm t 1 nj Q HH Cc UG 7 Multiuser Mode Partitions Remember that in Multiuser Mode the G H O and P partitions are reserved for diskette operation their corresponding Diagnostic Mode partitions H I P and Q have no purpose when operating in Diagnostic Mode If the partitions l
