在linux下安装hp多路软件步骤

1、步骤一、确认信#rpm-qa|grep device-#more 步骤一、确认信#rpm-qa|grep device-#more #/sbin/scsi_id-g -u-s #/sbin/scsi_id-g -u-s #/sbin/scsi_id-g -u-s #/sbin/scsi_id-g -u-s 步骤二、安装HPDMMultipath HYPERLINK http:/h/ -devnodehda 2、添加多路径 multipaths multipath devnodehda 2、添加多路径 multipaths multipath multipath multipath #cd /m

2、nt#tar-zxvfHPDMmultipath-4.4.1.tar.gz #cd HPDMmultipath-4.4.1：#/etc/init.d/multipathd restart步骤三、配# vi /etc/multipath.confmultipath 会把所有设备都加入到（devnode *），也就是 #devnode multipath multipath /sbin/scsi_id-g-u-spath_prio_alua /sbin/scsi_id-g-u-spath_prio_alua /sbin/scsi_id-g-u-spath_prio_alua /sbin/scsi_

3、id-g-u-spath_prio_alua /sbin/scsi_id-g -u-s For /sbin/scsi_id-g-u-s For vendor /sbin/scsi_id-g-u-spath_prio_alua）步骤 vendor /sbin/scsi_id-g-u-spath_prio_alua）步骤四：查看结#multipath -db-data02(360014380125d9e2300005000000b0000)dm-1size=800Gfeatures=1_round-robin_3:0:1:2 _4:0:1:2 _round-robin_3:0:0:2 _4:0:0

4、:2 8:80 db-data01)dm-0size=1000Gfeatures=1_round-robin_3:0:0:1 _4:0:0:1 _round-robin_3:0:1:1 _4:0:1:1 8:128db-oracle)dm-3size=200Gfeatures=1_round-robin_3:0:1:4 _4:0:1:4 _round-robin_3:0:0:4 _4:0:0:4 8:1128:48 8:176db-quota(360014380125d9e2300005000000f0000)dm-2#/etc/init.d/multipathdsize=1.0Gfeatur

5、es=1_round-robin_3:0:0:3 _4:0:0:3 size=1.0Gfeatures=1_round-robin_3:0:0:3 _4:0:0:3 _round-robin_3:0:1:3 _4:0:1:3 8:32 8:96 8:224activeready说明设备已经配置完毕，可以看到，4 个设备，设备的位置在/dev/mapper 下。步骤五：multipathd 服务设置成开机自启# chkconfig multipathd#ls -lrt crw-1rootroot 10,6008-2406:26brw-rw-1rootdisk253, 208-2406:58/dev/mapper/db-brw-rw-1rootdisk253, 108-2406:58/dev/mapper/db-brw-rw-1root
