linux 主機掛接EVA 4000儲存的操作步驟
環境:
HP DL380(redhat as3 u8)+光纖卡(2*qla2000)+EVA 4000,採用直連方式掛機儲存,EVA上的Vdisk已經劃分完畢。
具體操作步驟:
[@more@]1.安裝qla2000光纖卡驅動程式.
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 //顯示掛機EVA硬碟的硬體路徑
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.對硬碟經行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)

Changed system type of partition 1 to 8e (Linux LVM)
Command (m for help): p

Command (m for help): w
The partition table has been altered!
Calling ioctl() to re-read partition table.
Syncing disks.
格式化完畢,再次透過fdisk -l檢視資訊如下:
Disk /dev/sdb: 524.2 GB, 524289048064 bytes
255 heads, 63 sectors/track, 63741 cylinders

Device Boot Start End Blocks Id System
/dev/sdb1 1 63741 511999551 8e Linux LVM
現在就可以對/dev/sdb1硬碟進行pvcreate等卷組和邏輯卷系列的命令操作
[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
