RHEL 5中如何使用multipath配置ASMdisk

fdisk查看磁碟

[root@db11g ~]# cat /etc/redhat-release

Red Hat Enterprise Linux Server release 5.9 (Tikanga)

[root@db11g ~]#

[root@db11g ~]#

[root@db11g ~]# fdisk -l

Disk /dev/sda: 32.2 GB, 32212254720 bytes

255 heads, 63 sectors/track, 3916 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes

  Device Boot      Start         End      Blocks   Id  System

/dev/sda1   *           1          13      104391   83  Linux

/dev/sda2              14        3916    31350847+  8e  Linux LVM

Disk /dev/sdb: 17.1 GB, 17179869184 bytes

255 heads, 63 sectors/track, 2088 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes

Disk /dev/sdb doesn't contain a valid partition table

Disk /dev/sdc: 10.7 GB, 10737418240 bytes

255 heads, 63 sectors/track, 1305 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes

Disk /dev/sdc doesn't contain a valid partition table

擷取scsi id

[root@db11g ~]# /sbin/scsi_id -g -u -s /block/sdb

SATA_VBOX_HARDDISK_VB3c0bb909-10aab3a0_

[root@db11g ~]# /sbin/scsi_id -g -u -s /block/sdc

SATA_VBOX_HARDDISK_VB3edd7dc1-fd831bf4_

在RHEL6下使用以下命令

scsi_id --whitelisted --replace-whitespace –-device=/dev/sdb

安裝multipath rpm包

[root@db11g ~]# yum install device-mapper*
