 For my senario,the fdisk -l shows 3TB hdd connected as /dev/sdb


1. So started parted using ,
           parted /dev/sdb

2.  create gpt disk label,
           mklabel gpt

3. change unit to TB
           unit TB

4.  create 3TB partition
         mkpart primary 0.00TB 3.00TB

5. fdisk -l , shows that a new partition /dev/sdb1 is created of 3TB in size

5.   To format as EXT4 filesystem,

Find HBA WWPN in RHEL / CentOS 5.x

Find HBA WWPN in RHEL / CentOS 5.X

Method1:

1) Run the following command to find the manufacturer of the HBA card


[root@host ~]# lspci |grep -i HBA
07:00.0 Fibre Channel: QLogic Corp. ISP2532-based 8Gb Fibre Channel to PCI Express HBA (rev 02)
0a:00.0 Fibre Channel: QLogic Corp. ISP2532-based 8Gb Fibre Channel to PCI Express HBA (rev 02)

2) To find the WWPN number use the following command and look for port_name

 systool -c fc_host -v

[root@host ~]# systool -c fc_host -v |grep "port_name"
    port_name           = "0x500XXXXXXXXXXX7e"
    port_name           = "0x500XXXXXXXXXXX4a"


Method2:

[root@host ~]# cat /sys/class/scsi_host/host1/device/fc_host\:host1/port_name
0x500XXXXXXXXXXX7e
[root@host~]# cat /sys/class/scsi_host/host0/device/fc_host\:host0/port_name
