Can't use full capcity of 1TB disks

Sorry misspelled Jumper setting..

Please post model Number of drive

Its SATA drive. If I put it as the root disk it configures the full space for my secondary disks. This is SATA (see above), there is no jumper setting on the back like IDE

Thank you

Strange but it sounds like LBA issue. Is LBA enabled on this machine?

Here's a useful bit of examples to read...

And then what you might like to do is use "format -e" and use an EFI label, reportedly it works better with larger disks.

In order for Solaris to support 3rd party disks, you need to add an entry to the /etc/format.dat file.

Here's some pointers:

http://docs.sun.com/app/docs/doc/805-7228/6j6q7uetg?a=view   (Adding a Third-Party Disk to Solaris)
http://docs.sun.com/app/docs/doc/805-7228/6j6q7ueu0?a=view  (search for format.dat)

You need to obtain the correct parameters from the manufacturer's documentation.

EFI labels are required for disks larger than 1 terabyte on systems that run a 64-bit kernel. You could try labelling the disk with an EFI label using the format -e command. EFI labels are only supported from sol9 onwards.

Sounds like the system hasn't been able to figure out the correct disk geometry. If you fire up format and select said disk and type 'inq' at the prompt. You'll get back the vendor, product and firmware revision. Also, get the value of pcyl, nhead, and nsect using the 'ver' option. To roughly get the size of the disk that is in the label do some multiplication.

pcyl * nhead * nsec * 512. Take that number and convert it to gb. Google "nnnn bytes into gigabytes" where nnnn is the number you derived from the previous calc. If you've labelled the disk correctly, you should have a near enough match. If not, your label is wrong. Ensure you define the correct label. Us the 'type' (from within the format -e) and selecting option 'default'.

hth.

It sounds like a partitioning problem.
Please run these commands and post the results.

# format
(select the disk)

type par (enter)
then type pr (enter)

what you should now see is the partition table for the disk, please post this.

Guys,

Thank you for your help so far, here is the output;

As you can see I have 930Gb on the backup partition, however I can't edit that to move to another partition. It just tells me I'm out of range

Thank you

Also,

This is the Gemetry of the disk I believe. I got it off another user of a linux machine
