This is caused when you have removed a previously mounted T3 volume and created a new one of a different size.

For instance, before removing the T3 volume named "sizetest", format looks like this:

    
Part      Tag    Flag     Cylinders        Size            Blocks
  0       root    wm       0 -    63      128.00MB    (64/0/0)       262144
  1       swap    wu      64 -   127      128.00MB    (64/0/0)       262144
  2     backup    wu       0 - 34144       66.69GB    (34145/0/0) 139857920
  3 unassigned    wm       0                0         (0/0/0)             0
  4 unassigned    wm       0                0         (0/0/0)             0
  5 unassigned    wm       0                0         (0/0/0)             0
  6        usr    wm     128 - 34144       66.44GB    (34017/0/0) 139333632
  7 unassigned    wm       0                0         (0/0/0)             0      

The vol list output looks like this:

volume        capacity   raid   data     standby
      
sizetest       71.6 GB    0     u2d1-4    none 
         

Remove the volume "sizetest" by running

stor-t300-d:/:<9>vol unmount sizetest
stor-t300-d:/:<9>vol remove sizetest

Create a new volume called "sizetest", but make it a different size.� Make sure to initialize it and mount it.�

(Duplicated when "vol init fast" is used...)

Now, vol list shows this:

volume        capacity   raid   data     standby
      
sizetest      143.2 GB    0     u2d1-8    none 
         

In format, do partition>print and the output will look the same as before:

Part      Tag    Flag     Cylinders         Size            Blocks
  0      root     wm       0 -    63      128.00MB    (64/0/0)       262144
  1       swap    wu      64 -   127      128.00MB    (64/0/0)       262144
  2     backup    wu       0 - 34144       66.69GB    (34145/0/0) 139857920

  3 unassigned    wm       0                0         (0/0/0)             0
  4 unassigned    wm       0                0         (0/0/0)             0
  5 unassigned    wm       0                0         (0/0/0)             0
  6        usr    wm     128 - 34144       66.44GB    (34017/0/0) 139333632
  7 unassigned    wm       0                0         (0/0/0)             0
       

This is where the problem is now seen by the customer because the customer is expecting to see a size of 133.38gb in format, but only sees 66.44gb.

The way to fix this is to run format, choose the device and then the "type" option.� You will see something like this:

Specify disk type (enter its number)[20]:

Choose "Auto configure" and you will see an output like this:

c2t2d1: configured with capacity of 133.38 GB
<SUN-T300-0116 cyl 34145 alt 2 hd 32 sec 128>
selecting c2t2d1
[disk formatted]

Next, label the disk and then do "partition>print" and you will now see the correct size in format:
