How to add new Iscsi disk

Use the following steps to create a new iscsi disk on sun solaris (10)

1. Define the disk in the storage gui
2. Login as root to the system
3. Enable Iscsi:
   
   iscsiadm modify discovery -s enable
   iscsiadm list discovery-address -v
   
4. Define Iscsi:

1. svcs -a | grep -i iscsi
   you should get : disabled       Jan_22   svc:/network/iscsi_initiator:default

2. iscsiadm list initiator-node
   you should get : Initiator node name: iqn.1986-03.com.sun:01:0003ba321f11.4523d4a8

5. Rescan iscsi to find new disks
1. devfsadm -C -i iscsi
   this command scan for new disks. please note -C is to cleanup old disks definitions , -i is for iscsi only
6. Use format to define new partitions
1. format
   you should get a list of disks like that -
   AVAILABLE DISK SELECTIONS:
   0. c0t0d0
   /pci@1c,600000/scsi@2/sd@0,0
   1. c0t1d0
   /pci@1c,600000/scsi@2/sd@1,0
   2. c2t1d0
   /iscsi/disk@0000iqn.2005-10.com.xivstorage%3A0101230000,0
   3. c2t2d0
   /iscsi/disk@0000iqn.2005-10.com.xivstorage%3A0101230000,1
   4. c2t4d0
   /iscsi/disk@0000iqn.2005-10.com.xivstorage%3A0101230000,2
   5. c2t5d0
   /iscsi/disk@0000iqn.2005-10.com.xivstorage%3A0101230000,3
   Specify disk (enter its number):
2. 3
   choose one of the disks if you get Disk not labeled. Label it now? - put yes
   
3. FORMAT MENU:
   disk - select a disk
   type - select (define) a disk type
   partition - select (define) a partition table
   current - describe the current disk
   format - format and analyze the disk
   repair - repair a defective sector

   analyze - surface analysis
   defect - defect list management
   backup - search for backup labels
   verify - read and display labels
   save - save new disk/partition definitions
   inquiry - show vendor, product and revision
   volname - set 8-character volume name
   ! - execute , then return
   quit
   partition (or p as shortcut)
   print (or p as shortcut)
   quit
   quit (to exit format)
7. Create a new file system
1. newfs /dev/rdsk/c2t2d0s6
   you should get newfs: construct a new file system /dev/rdsk/c2t2d0s6: (y/n)?
   press - y
2. mount /dev/dsk/c2t2d0s6 /oracle
