B.10 Resizing LUNs Greater Than 1 Tbyte

When a LUN is created larger than 1 Tbyte, the Solaris operating system identifies the LUN as an EFI drive. If the LUN is later rebuilt to less than 1 Tbyte, it retains the EFI label. If you want the LUN to revert back to SMI labeling, the format -e label command is required.

To relabel a LUN to less than 1 Tbyte, perform these steps:

Note – In this example, the LUN being relabeled is c1t2d3.

1.Type the format command in a terminal window:.

#format -e devicename

2.At the format> prompt, type label.

#format -e c1t2d3

format> label

Two menu items are displayed and you are prompted to choose between them:

#format -e c1t2d3 format> label

[0]SMI Label

[1]EFI Label

Specify Label type[0]:

3. Select option 0 (SMI).

Specify Label type[0]: 0

4. Respond to the on-screen prompts to relabel the device.
