Solaris 11 disk issue[solved]

I have 2 disks in my system.I recently added a zpool to the disk, but today I changed my mind and deleted the zpool ,
zpool destroy -f extra

The zpool is now deleted and I want to partition the disk, so I delete the only partition on the disk.

Now when I run format again,

Code:
format
Searching for disks...done


AVAILABLE DISK SELECTIONS:
       0. c7d0 <SAMSUNG-S14JJ9DP72414-0001-149.05GB>
          /pci@0,0/pci-ide@1f,2/ide@0/cmdk@0,0
       1. c8d1 <drive type unknown>
          /pci@0,0/pci-ide@1f,2/ide@1/cmdk@1,0

Specify disk (enter its number): 1



AVAILABLE DRIVE TYPES:
        0. other

My issue is I can see the drive but I cannot access it (pressing 1)to partition it,I get the message above.Can anyone help?

Did you try create zpool again?
Code:
# zpool create extra c8d1

It should write new label to disk and then you could destroy pool and modify label with format

What platform is this?

What type of disk is it?

(depending on what type of disk it actually is, I would firstly "set all mode pages to default" using the format command. A disk drive is a highly programmable device and has a large number of on-board registers which define its behaviour. If these are left in a state of limbo by some operation, the drive might exhibit strange behaviour. Also, you should be able to write (or rewrite) a Sun label to the disk using format or even redefine its perceived geometry. Don't forget that you can invoke format with a -e switch (expert mode) which provides much more ammunition to tackle things. In expert mode make damned sure you select the right drive to work on otherwise you could alter working drives.)

Anyway, enough of all that. Post back answers to above questions.

This worked fine, but the issue is I wanted to actually partition the disk then use one partition for NFS ,SMB etc. If I just create back another pool, I have access to the disk , but not able create partitions.

The disks are SATA disks
Thank you all for the replies.I still am back at square one, at how to partition the disk,when I tried the last time, it told me I needed to delete the partition, then create the needed partitions ,but disk became inaccessible when I deleted the only partition.

I understand what you want, but now disk is inaccessible from format command. My advice is to create zpool again. It will write new label to disk. Then you must destroy zpool but label will still exist and disk will be accessible from format command.
Why did you delete partition before? Did you use fdisk subcommnd from format?
I usualy use format in different way.
First I check disk and then from menu select partition, then print and then you can see how disk is partitioned and by selecting number of partition you can change it.
It is x86, so you probably removed solaris main partition which is something different than solaris slice.

Yes, as I said in my previous post, I was able to create the pool again, and it is now online. I can destroy the pool again and then be able to access the disk, but still am stuck at how to partition the disk.

Yes, I used fdisk subcommand, this is the disk after I created a label:
Code:
 Total disk size is 9725 cylinders
             Cylinder size is 16065 (512 byte) blocks

                                               Cylinders
      Partition   Status    Type          Start   End   Length    %
      =========   ======    ============  =====   ===   ======   ===
          1                 EFI               0  9725    9726    100

I want to know how can I create a couple partitions.

It seems you are confusing partitions and file systems here. You certainly can create new file systems in your existing ZFS pool and dedicate them to NFS, SMB or whatever you want.
