This Linux user ID will have the following minidisks and virtual disks (VDISKs):
Table 8-1 Minidisks to be defined
Minidisk Description
100-101 Minidisks used to create the root file system, plus a logical volume
containing the other file systems of the Linux golden image.
300-301 These are virtual disk (VDISK) swap spaces that are not defined in USER
DIRECT file, but defined by calls to the SWAPGEN EXEC in the user’s
PROFILE EXEC so that when the user ID logs on the VDISKs are created.
► Go back to the top of the file and search for string USER $ALLOC$. Add cylinder 0 of the new
volume (or volumes) to this dummy user ID so they don’t show up as gaps in the USER
DISKMAP report file. In this example, one new volume is being used - UM63A9:
====> top
====> /user $alloc$
USER $ALLOC$ NOLOG

EOJ DIRECTORY UPDATED AND ON LINE
You have now defined the user ID that will be the master Linux image.
8.1.2 Adding RH6GOLD to AUTOLOG1’s PROFILE EXEC
The new Linux ID you defined needs access to the VSWITCH. Just as with the RH6CLONE
user, a SET VSWITCH command with the GRANT parameter will now be added to AUTOLOG1’s
