| 8 | ## Creating a valid Legion disk image | |

| 12 | ## Steps for creating a disk image for simulation use. You | |
| 13 | ## will need to ensure that the amount of disk space used | |
| 14 | ## in your root filesystem is small enough for the disk | |
| 15 | ## you are creating (or the disk is large enough for the | |
| 16 | ## root partition you are cloning).. | |

| 35 | ## Currently, legion needs a valid disk label on your disk image. | |
| 36 | ## It will then overwrite this with the new values for the slices | |
| 37 | ## you specify in your legion conf file and it creates a valid | |
| 38 | ## s2 size to represent the entire disk. | |
| 39 | ## | |
| 40 | ## This needs to be fixed so that legion can create the entire | |
| 41 | ## label on it's own, regardless of what's in the first 512 | |
| 42 | ## byte block of the disk | |
| 43 | ## | |
| 44 | ## Until this is done, you need to add a label to a disk image | |
| 45 | ## as follows: | |

| 53 | ## To make a disk bootable under legion you will | |
| 54 | ## need the following config changes: | |
| 55 | ## note: $BIN is a reference to /home/mo23723/workspace/snapshots/disks/bin | |

| 59 | - Add [hsimd "SUNW,legion-disk"] to /mnt/etc/driver_aliases | |
| 60 | - Add [hsimd 246] to /mnt/etc/name_to_major (ensure number not already in use) | |
| 61 | - Add hsimd driver as follows: | |
| 62 | # cp $BIN/hsimd /mnt/platform/sun4v/kernel/drv/sparcv9/hsimd | |
| 63 | # cd /mnt; cpio -icdB < $BIN/devices.cpio XXX Show list of devicesto create XXX | |
| 64 | # cp $BIN/vfstab /mnt/etc/vfstab | |
| 65 | - remove root passwd | |
| 66 | - comment out smf startup line in /etc/inittab | |
