Verifying Partition Tables

  1. Upon boot up completion, the Target system will be in SINGLE USER MODE, where we can format and partition the target disks in preparation for migration. Run the format command to review our disk configuration.

In this example, Target disk 0 reports c0t1d0. This represents Controller 0, SCSI id 1, device 0. The other outputs from the format command are described below.

Output Description Value
cyl Cylinders 2226
alt Alternate Cylinders 2

sec Sectors per Cylinder 63
  1. Let’s review the partition table configuration of our Target disk. For Specify Disk, enter disk 0 and type yes to label the disk. Charon SSP Connection

  2. Under the FORMAT MENU, type partition then print to examine the partition table of the Target environment. Charon SSP Connection

In order for the migration to be successful, we need to make sure that the size of all Target file systems are of equal or larger than the Source file systems. We also need to ensure that our Target environment has the same geometry and partition layout as our Source environment.

  1. Repeat steps 1 through 3 in the Source system to print its partition table. At this point, it is strongly recommended to keep both Source and Target console sessions side by side as shown in the screenshot below.
