linux 主机挂接EVA 4000存储的操作步骤

环境：

HP DL380(redhat as3 u8)+光纤卡（2*qla2000）+EVA 4000,采用直连方式挂机存储，EVA上的Vdisk已经划分完毕。

具体操作步骤：

1.安装qla2000光纤卡驱动程序.

2.cd /opt/hp_fibreutils ;hp_rescan -a

Sending rescan signal to /proc/scsi/qla2300/0...
Sending rescan signal to /proc/scsi/qla2300/1...
Removing /proc/scsi/qla2300/0, target 0, LUN 32 Scanning /proc/scsi/qla2300/0, target 0, LUN 32

scsi0 00 00 01 HP HSV200 6000 Direct-Access
scsi0 00 00 00 HP HSV200 6000

3.fdisk -l //显示挂机EVA硬盘的硬件路径

isk /dev/sda: 214.7 GB, 214748364800 bytes
255 heads, 63 sectors/track, 26108 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytesDisk /dev/sda doesn't contain a valid partition table

4.对硬盘经行linux LVM格式化

fdisk /dev/sdb
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel. Changes will remain in memory only,
until you decide to write them. After that, of course, the previous
content won't be recoverable.

The number of cylinders for this disk is set to 63741.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)
Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)

格式化完毕，再次通过fdisk -l查看信息如下：

现在就可以对/dev/sdb1硬盘进行pvcreate等卷组和逻辑卷系列的命令操作

[root]# pvcreate /dev/sdb1
pvcreate -- physical volume "/dev/sdb1" successfully created

[root]# vgcreate -s 16 -l 255 /dev/vg_data /dev/sdb1
vgcreate -- INFO: maximum logical volume size is 1023.97 Gigabyte
vgcreate -- doing automatic backup of volume group "vg_data"
vgcreate -- volume group "vg_data" successfully created and activated
